When Determining what type of Drain you need for your Drainage System.  In our last blog, we talked about Surface Water and Sub-Surface water and why you need to understand them before designing your Drainage System.  If you need to review, click below.  If you have a question or comment please leave it at the bottom of the page. I will respond as quickly as I can.

Before we get into Water Movement, we need to discuss Surface Drains.

Surface Drains come in many shapes and sizes.  The two most common are Basin Drains and Channel Drains.

A Basin Drain has a Square Grate and it sits on top of a catch basin.  It will have a single pipe connected to it or it will have a drain pipe running into it and a pipe running out of it.  We used this picture in a previous blog, but I want to show it to you again.

Surface Drain Connection

Surface Drain connected to a Transition Pipe

Below is a Basin before the pipe is connected to both sides.  The pipe is cut and connected to one side.   Another piece of Drain Pipe is connected to the other side.  The Drain pipe does not run straight through the basin.  Water must have a way to enter the Drain Pipe.  The Surface Drain in the picture is the most common size used in residential applications.  The Drain Pipe connecting to it is 4 inch ADS Solid Drain Pipe.

For a Surface Drain to work well it must be placed in a low lying area of standing water.  It is not intended to intercept moving water or to drain away Sub-Surface water.

 

In review, detecting Surface Water is straight forward.  You can observe how it flows into the Problem Drainage Area.

Sub-Surface water is not so easy.  You can’t see it move into the problem area.  So What do you do?

First take a look at your soil.  What type of soil do you have?

Soil with a lot of clay will have less Sub-Surface Water, Maybe none at all.  If you do have some it will move into the area slowly.  If you have sandy soil the underground water will move there in a hurry.  Most people will have something in between.

To be sure, a few simple tests can help.

Next check the problem drainage area when there is no water standing in it.  Is it soft and mushy when the surrounding area is more firm?  This is an indication that Sub-Surface Water is still flowing into the area.  Another way to collect information is to dig a small hole about a foot deep in the area. Check it every day for several days.  If water is standing in the hole, you have a Sub-Surface Water issue.  How fast it flows into the hole is also important.

OK, you have Sub-Surface water along with Surface Water in your problem drainage area.  Your Choice for the correct “Intake” for your Drainage System should be a French Drain.

OK, You have no Sub-Surface water. You only have Surface Water flowing into the problem area.  You need a French Drain If you are trying to intercept the water as it comes into the area.  Many times water will run around the surface drain and still flood the area.  Also the Surface Drain is much more easily overwhelmed and water will run past it that way too.  Again, this is very important,  If you are trying to intercept water before it gets to where its going, don’t use a Surface Drain.

A Surface Drain should be used in a Medium to Low Volume Water situation.  The water needs to be stationary or moving very slowly.  It should be placed in an area that is the lowest point in the Problem Drainage area.  They also work well in smaller confined areas such as pool decks, along sidewalks, or in flower beds.

More than one Surface Drain can be connected to one drain pipe in a “Daisy Chain” of Drains if you have several low spots in a larger area.

In many cases a small french drain can be installed in almost every place that a Surface Drain might be installed.  People opt for a Surface Drain over a French Drain because they like the way the Surface Drain looks more than the way the French Drain looks.  For some People, Looks are more important than functionality.

Channel Drains are set in concrete or dirt but dirt is not always the best idea.  Setting a channel drain in dirt should only be done when a shallow surface drain is needed and that is the only option.

Setting a Surface Drain in Concrete such as a driveway or a Sidewalk is a good application for a Surface Drain.  Many times it is better to install a French Drain in your yard over a Surface Drain.  What ever makes you happy!

French Drains can be made to look very decorative.

French Drains can be decorated with many types of stone

In conclusions,

French Drains are used for :  1.  Higher water volume situations  2.  Intercepting moving Surface Water  3.  Solving Sub-Surface water problems

Surface Drains are used for: 1.  Smaller water volume situations  2.  Standing Surface Water that has reached its destination   3.  Smaller and more confined areas  4.  Set in concrete such as sidewalks or Driveways

A French Drain is just a part of a Drainage System.  Many people refer to basically any type of Drain in or around their home as a French Drain.  This actually in not correct.

Gutter to French Drain

Connecting Gutter to French Drain

Before you can really understand what a French Drain is, you first must be familiar with a Drainage System and what it involves.

A Drainage System has three parts.  It has an “Intake” to bring water into the Drainage System.  It is placed in a low area where water is standing or is in area where water sometimes runs across it over the surface or under the surface or both.  An “Intake” will be a French Drain, Surface Drain or Sump Pump.

In a Simple Drainage System there will only be One “Intake.”  In a Complex Drainage System there will be several Intakes.  They may vary in type and size.  For Example, You may have a Drainage System with a Surface Drain, and a French Drain and a Sump Pump all as separate  Intakes in the Drainage System.  The Intakes will vary in number and type depending on what water issues you are trying to fix.

The “Transition” is the second part of the Drainage System which is the Drain Pipe that moves the water out of the area that is flooded.  It is your water “High Way, ” as it were.  Typically there are two types of Transition Drain Pipes that will be covered later.

Finally you have an “Exit” which releases the water from the drainage system.  It must be in an area that is lower than the French Drain or Surface Drain that is you “Intake.”

Connecting Gutter Down Spout to French Drain Under Sidewalk

A French Drain  is a perforated pipe that is basically full of slits or holes.  A trench is dug across the problem drainage area.  The dirt from the trench is hauled away.  The perforated pipe is placed in the trench.  The Drainage trench is dug deep enough so that the perforated French Drain Pipe is several inches below ground level when placed in the trench.  Next gravel or some type of crushed stone is placed on top and around the French Drain perforated pipe until the trench is full.

 

Once a French Drain is completed you will see gravel on the surface in a place where dirt use to be.

A French Drain is designed to take in and move a large amount of water.  It covers a large area with water standing on or moving across the area.  It needs to have some “Slope” or “Fall” to drain the water.  The pipe needs to run down hill to the exit point to release it from the Drainage System.  If it is up hill in all directions from the French Drain then there is a problem.  We all know that water will not flow up hill.  Some times this can be overcome when it is only slightly up hill by digging the trench deeper as you go up hill.  Still the exit point in the Drainage System must be lower than the French Drain where the water is taken into the drainage system, or the water will never drain.

In conclusion, a French Drain is a perforated Pipe in a trench covered in gravel.  It is the “Intake” part of a Drainage System.  It covers a wide area and needs to be higher than the exit point of the Drainage System.

This is the first in a series of blogs about French Drains and all other types of Drains as well.  If you would like to learn more just Click on the “Next Blog” below.

FRENCH DRAIN AS PART OF A DRAINAGE SYSTEM

 

 

Drainage Systems can be made up of one drain or a combination of many drains.  Drainage  problems can be very complex.   Complex Drainage Problems may require a combination of several different types of drains all inter-connected and working together.  Other times the drainage problem may be simple and straight-forward requiring only one drain or several of the same type of drain connected together.

An example of a complex drainage system would be:  A French Drain in the back yard connected to a Surface Drain near a flower bed connected to several gutter downspouts, which are connected to a Channel Drain going across a driveway, which is connected to additional Surface Drain in the front yard, which runs to a Curb Fitting that lets all the water drain out on to the street.

A simple Drainage System might consist of a Surface Drain that is connected to a second Surface Drain which runs to aPop-up Emitter which lets water drain over the curb and into the street.

Oklahoma Drainage Installs all types of Drainage Systems.

Today we installed a 6 Inch French Drain at an apartment complex near Lake Heffner.  The French Drain started in the back yard of one unit.  The Drain Pipe went under the fence and into the adjoining unit’s back yard.  The French Drain then looped around their patio and out under their fence to the west.  To get the 6 inch Drain Pipe to the correct Exit Point, we had to cut out 30 feet of sidewalk and run the French Drain Pipe under the sidewalk.  Next, we replaced the sidewalk with new concrete.  Finally, we dug a drainage ditch across the front yard to the parking lot.  We covered the Drain Pipe with sod that we carefully removed when digging the trench.  At the edge of the parking lot a 6 inch Pop-Up Emitter was installed to release the Storm water.  Seven Gutters were connected directly into the Drainage System along the way.

This particular Drainage System was made up of 55 Feet of 6 inch French Drain, 78 Feet of Solid ADS Solid Drain Pipe, Seven Gutter Connections, and one 6 inch Pop-Up Emitter.

We Install Drainage Systems to fit various needs for home owners an businesses.  A Drainage System, can utilize French Drains, Surface Drains, Channel Drains or Sump Pumps as the intake part to the Drainage System.  The Drain or Sump Pump brings water into the Drain Pipe.  The Drain pipe takes the water to the ” Exit.”  Which is Either a “Curb Outlet” or a “ Pop Up Emitter.”

The Three parts of A Drainage System are:   THE  INTAKE ( French Drain or Surface Drain ) etc.  The TRANSITION ( The Drain Pipe ) which can be many sizes or type. The EXIT ( A Curb Outlet or Pop Up Emitter )

The Drainage part of our company name means that we solve water problems for people in Oklahoma.  Heavy rain is becoming more common.  Back in 1993 when I first started, a hard rain was considered to be about an Inch per/hour.  It was fairly rare but not too uncommon.  Today things are different.  A weather report of rain fall at or above 4 inches per/hour was not uncommon in 2019.  Excess water causes all types of damage to property both residential and commercial.

Our Drainage Systems drain water away from places you don’t want it to be.  You might have water standing along the foundation of your house, or inside your basement.  You might have water on your driveway or flowerbed too.

Designing a French Drain or a Drainage System

When I talk to a potential customer while doing a Drainage System estimate, I take a lot of things into consideration.  First I have the Customer show me where water is standing or where it is going that it shouldn’t.  This is part of defining the specific problem area.  Sometimes the Water Problem Area is larger and more involved than the customer realizes.  Once the Water Problem Area is clearly defined,  the next step is to determine how the water is getting to the problem area.  Many times there is more than one Water Source to the Water Problem area.  A big mistake in Drainage System Design is to stop once the most obvious  Water Source is found.  A Drainage System Designer must be a detective to some degree.  For Example:  Water running down the hill and onto the back patio might be the most obvious water source.  Sub-surface water or a neighbor’s new gutter downspout could also be contributing.  Most of the time water gets into the problem area from more than one source.

This is a good place for a French Drain

Next you must decide where to take the water.  This is determining an Exit Point for the Drainage System.  If possible you want your exit point to be down hill from the problem area.  If it is up hill in all directions from the problem area, then the only solution is a Sump Pump.

Once an exit Point is determined, you must ask yourself if there is any way to install two exit points.  Usually this can only work when an exit point can work on both ends of a Drainage System.  The benefit of two Exit Points in a Drainage System is it greatly increases the water capacity for the Drainage System.  It can move much more water faster during a heavy rain than a system with just one Exit Point.  Most Drainage Systems can only utilize one Exit Point.  In 21 years of Drainage System Installation,  I would say 10% of our Drainage Systems have two Exit Points.

Next we have to decide what type of drain to install in the problem area.  If it is a small area with one water source, Usually a Surface Drain is best.  If the water problem area is large with one or several water sources, a French Drain is usually installed.

If you have several problem drainage areas you must use larger Drain Pipe if you want to connect them together  to one exit point.  Large French Drains should have their own exit point without attaching other Surface Drains or Gutters to them.  It is very common to connect too many drains or gutters into a Drainage System.  A hard rain can overwhelm the Drainage Systems Water Flow Capacity.  When that happens, water backs up and the problem area floods.

I just shake my head when I see 3 French Drains and 5 gutters connected into one exit drain pipe. I see this type of design all the time.  Why spend money for a Drainage System that won’t work?  Lots of Cheap Builders and Fly-By-Night Drainage Companies cut corners on Drainage Systems and French Drains on new home construction.

For a French Drain or a Surface Drain or any type of Drainage System,  If in doubt, use a larger Drain Pipe.  Four Inch Drain Pipe is the most common. Six inch Drain Pipe is always better.   If you are going to connect a French Drain and Surface Drain together, use 6 inch Drain Pipe.

When Installing a French Drain as part of a Drainage System, there are many things to consider.

What is the primary source of water coming into the problem drainage area.

Are there secondary sources of water entering the area.

What are they and how many.

How fast does water enter the area and how often.

What are the potential exit points for the water,  Where do we want to take the water too.  Is there more than one potential exit point to increase drainage capacity.

Does the customer want a Drainage System or a Flood Prevention System and does he understand the difference.

Just what is a “French Drain?” Many times people incorrectly

French Drain can protect your foundation!

use the phrase, “French Drain,” when they mean “Surface Drain” or “Channel Drain.”

A basic French Drain consists of a Perforated Drain Pipe in the bottom of a trench. The French Drain Trench runs through a Problem Drainage Area that needs to be drained.   The French Drain Pipe is perforated (Full of Small Holes) and has Neo-Prene Soc around the pipe.  This soc helps prevent debris from clogging the French Drain Pipe.

The dirt that was taken out to make the trench is hauled away. It is replaced by some type of small stone or gravel depending on what is desired or available. I prefer crushed 1 inch lime stone. It is the most economical option in my area. Pea Gravel or some other type of small stone can work just as well. The lime-stone or gravel is placed in the trench on top of the perforated Drain Pipe and filled all the way to the surface (ground level). In some cases where the French Drain needs to be deep or is being placed in sandy soil, a special trench liner must be placed in the trench before the perforated Drain Pipe or the Gravel are installed. This helps maintain the integrity of the trench over time. It also increases the cost of the French Drain and the amount of time to install it. I install a trench liner in a French Drain about 20% of the time. Most of the time a liner in not needed.

French Drain Gravel

Oklahoma Drainage recently diagnosed a Drainage Problem in  South Oklahoma City.  The Home owner had a sump Pump in their basement that was fed from a French Drain outside the Basement Wall.  The French Drain was 14 feet down along the Stem wall of the house.  The French Drain Pipe was cheap and had collapsed.  We brought in a Mini Excavator and dug up the pipe and replaced it with Durable ADS 4 inch perf/soc French Drain pipe.  In the end, we were able to dig up the pipe and Replace it.

French Drain Installation

Oklahoma Drainage  has been diagnosing and solving Drainage Problems since 1993.  Water has the ability to get into places around your home where you really don’t want it to be.  Some drainage problems are easy to solve.  Typically water enters the problem drainage area one way from one source.  The really tricky drainage problems occur when water enters the problem drainage area from multiple directions and from multiple sources.  Sometimes a secondary water source can’t be seen or identified until the primary water problem source is eliminated.

An example of this occurs when water is running into a problem area in an obvious way over the ground where you can see it.

Simple enough.

French Drain walk way

A drainage system is installed with a surface drain as the “intake” with drainage pipe running to an exit point.  Initially the water drains away and everything looks great.  The next day water is back and is all around the surface drain, but below the edge and it hasn’t rained at all, so no additional water ran over the surface of the ground to flood the area.  The primary water source was solved, ( The surface water run off ) but the secondary water source was not.  Which was sub-surface water, (ground water) running into the area.  A surface drain can’t drain “ground water.”  A French Drain should have initially been installed instead of a Surface Drain.  A French Drain can drain both Surface Water and Ground Water.

Keep water off your driveway with a channel drain

 Standing water comes from many sources.  It causes damage to  sidewalks, driveways, and foundations not to mention plants, trees, and  grass.  Does the side of your house flood because your neighbor doesn’t  have gutters, or does your sidewalk turn into a moat after a heavy rain,  or worst of all, is water seeping into your foundation and duct work  after a thunderstorm?  Theses are just a few of the Drainage  Problems that Oklahoma Drainage and Sprinkler Repair can help with.

We can design a Drainage  System to fit your specific needs.  We install many types  of Drains  to solve many types of problems.    French  Drains, Surface  Drains, Channel  Drains, Basement  Drains, Trench Drains, Basin Drains, and Sump  Pumps are utilized.

FRENCH DRAIN  CONNECTED TO GUTTERS

Many different types of Drains can be hooked together by one Drain Pipe.  The Drain Pipe then running to an Exit Point makes up a Drainage System.  One common type of Drain used in a Drainage System is A “French Drain.”  Many times a French Drain is installed close to a building foundation or in a low area next to a home or business.  This puts the French Drain in close proximity to Gutter Down Spouts.  Rather than have water come off the roof and out the Down Spout and on to the ground below, many times it is much better to tie a Gutter Down Spout Directly into a French Drain or near by Drain Pipe depending on the Drainage System Design.   Connecting The Down Spouts Directly into a French Drain is much  more efficient and causes suction to occur in the French Drain.  Connection of Gutter Down Spouts to a French Drain makes the Drainage System work better.

French Drains can protect your home and property from water damage.  Oklahoma Drainage and Sprinkler Repair installs a wide variety of Drains in many different places.  A Drain or Group of Drains with Drain Pipe going to an exit point is a “Drainage System.”

Drainage Systems can be made up of one drain or a combination of many drains.  Drainage  problems can be very complex.   Complex Drainage Problems may require a combination of several different types of drains all inter-connected and working together.  Other times the drainage problem may be simple and straight-forward requiring only one drain or several of the same type of drain connected together.

An example of a complex drainage system would be:  A French Drain in the back yard connected to a Surface Drain near a flower bed connected to several gutter downspouts, which are connected to a Channel Drain going across a driveway, which is connected to additional Surface Drain in the front yard, which runs to a Curb Fitting that lets all the water drain out on to the street. A simple Drainage System might consist of a Surface Drain that is connected to a second Surface Drain which runs to a Pop-up Emitter which lets water drain over the curb and into the street. An “Exit Point” is the term used for where all the water leaves the Drainage System.  Determining the Exit Point is very critical.  It is one of the first things we do when diagnosing a Drainage Problem. Drainage Systems can: 1.  Keep water away from foundations — A French Drain is best because it can move Surface Water and Sub-Surface Water (water moving under ground) away from the foundation.  Many times less experienced companies install Surface Drains to keep water away from foundations.  This can be a big mistake.  A Surface Drain can’t move or drain Sub-Surface Water.   Also A Surface Drain often can’t move enough water fast enough and easily becomes overwhelmed during a heavy rain.  A Surface Drain also can’t cover or protect a broad enough area. Surface Drains should be designed in a Drainage System to be located in smaller Drainage Areas moving moderate amounts of water.  Surface Drains look better than French Drains.  If ,”appearance” is more important than Drainage Capacity, Go with the Surface Drain.  Just know what you are getting into and what your expectations should be. One side of a foundation alone,  can be over 100 feet.  A 4 inch or 6 inch French Drain is best when protecting a large area such as a foundation. 2.  Keep water away from small or enclosed areas.  This might be a low area just through a gate on the side of a house, or the low area between a flowerbed and the wall of a house, or standing water on or near a sidewalk or driveway.  These types of Drainage Problems are best served with Surface Drains.  A Surface Drain can move water away from a low area that is relatively small.  This can occur in yards, flowerbeds, sidewalks and driveways.  A surface Drain is designed to move Surface Water away from a problem area to a predetermined exit point.  Surface Drains are available in many sizes.  How quickly they remove standing water is usually determined by the size of the pipe that is connected to the drain. Simply put, a Drainage System is one or a group of underground Drain Pipes that take water away from a place that has water standing on it or flowing across it.  The water that is in the problem area, can be causing damage or may be inconvenient or both.  (Usually Both)  A simple Drainage System is a Drain for the water to enter, a Drain Pipe to move the water away from the Drain, and an Exit Point for the water to be released out of the Drain Pipe. Drainage Systems quickly can become more complicated.  Considerations must include: How does the water get to the problem area?  There may be one or many sources. Water Sources: 1.  It falls from the sky directly 2.  It flows down hill over the surface (surface water) 3.  It flows underground under the surface (sub-surface water) 4.  It flows from the edge of a roof ( There may be many roofs near the problem area, neighbors etc.) 5.  It flows from a gutter downspout 6.  It flows over the edge of a gutter because the gutter is too small is is clogged 7.  It flows up from the ground (seeps and springs are common in Oklahoma) 8.  It flows from a sprinkler system use ( yours or your neighbors) 9.  It flows from a leaking pipe ( water mains, water meters, water lines, sprinkler pipes, sprinkler valves) There are other reasons for Drainage Problems, the above reasons are just the most common. Once the number of water sources is determined, a rough estimate of the amount of water that needs to be drained away on average must be estimated.  This can be simplified down to “SMALL, MEDIUM, OR LARGE AMOUNTS OF WATER TO BE DRAINED AWAY.  You don’t have to be an engineer trying to calculate fluid dynamics.  Experience at diagnosing drainage problems helps however.  How much water needs to be moved will help determine the type and size of the Surface Drain or French Drain that needs to be installed.  It also helps to determine the size of Drain Pipe required for the Drainage System.  A good rule to follow is, “If in doubt, install a larger Drain and Drain Pipe.”  Unused Drainage Capacity is better than property damage caused by a Drain that is overwhelmed by too much water. For home and small business use typical materials used are: 6 inch, 9 inch, and 12 inch Surface Drains – 3 inch, 4 inch, and 6 inch Drain Pipes — 3 inch, 4 inch, and 6 inch French DrainsFrench Drains move more water than Surface Drains — French Drains move Surface Water and Sub-Surface Water Surface Drains move Surface Water only Surface Drains look nicer than French Drains in most cases Once the type and number of drains is determined and what size Drain Pipe will connect them, an exit point must be selected.  (Where is the Drainage System going to take the water to and release it?) The Drainage Curb Fitting is installed when the desired exit point for the French Drain will release the Drainage Water into the Street.   The Drainage Curb Fitting is rectangular in shape and made to be installed through the curb.  A small section of Curb is cut out with a concrete saw.  The Section is a few inches wider than the Drainage Curb Fitting.  We then install new concrete around the curb fitting.  Once the concrete has dried, the Drain Pipe coming from a French Drain or Surface Drain is connected to the Drainage Curb fitting and then covered with dirt.

The Drainage Pop-Up Emitter is connected to the end of a Drain Pipe.  It is downhill from a French Drain or a Surface Drain.  It is a small release basin with a green pop-up lid.  When releasing water, it pops up about an inch to release the water from the French Drain or Surface Drain.  When the Storm Water has moved through the Drainage System and out of the Pop-Up Emitter, the green lid closes back to its original closed position.  The emitter is designed to release water out into a yard or down a hill or other desirable Drainage Exit Point where there is no curb.

Drainage System installation and design is a big part of our business.  Does your sidewalk turn into a moat after a hard rain?  Does part of your yard look like a pond after a thunderstorm?  Worst of all, are you experiencing concrete deterioration to your foundation, sidewalk, or driveway.  We can design a Drainage System to solve your Drainage Problems Our Drainage Systems can be simple or complex.  We utilize, French Drains, Surface Drains, Channel Drains, Basin Drains, Basement Drains, Trench Drains, and Sump Pumps.  Estimates are free!

Just what is a “French Drain?”  Many times people incorrectly use the phrase, “French Drain,”  to apply to many different types of Drains  that could be used in a Drainage System.   The term is widely used and many times incorrectly connected to “Surface Drains,” or “Channel Drains.” A Surface Drain has a grate that sits on top of a basin.  The basin is underground.  A Drain Pipe is connected underground to an outlet on the Drain Basin. Storm-Water Drains through the grate into the Drain Basin.  Once in the Drain Basin, water travels out of the basin through a Drain Pipe.  The Storm-Water continues downhill in an underground Drain Pipe to an exit point.

A Surface Drain may come in many different shapes or sizes.  It is a Drain Basin with a Drain Grate on top and a Drain Pipe connected on the side.  The Drain Grate may be round or square.

A Channel Drain is a type of Surface Drain and many times is installed in concrete across sidewalks or driveways.  It is long and narrow with a grate on top.

A French Drain is completely different from a Surface Drain.  A basic French Drain consists of a Perforated Drain Pipe in the bottom of a trench.  A  Trench Liner is sometimes used depending on the Drainage System Design and the type of soil.   The Drain Pipe should have a neoprene sock around the Perforated Drain Pipe.   This is to ensure that the Drain Pipe does not become clogged.

A trench is dug that is slightly wider than the French Drain Pipe that is being used.  There are several sizes.  Three Inch, Four Inch, and Six Inch are the most common sizes of French drain Pipe. The dirt that is taken out to make the trench is hauled away.  It is replaced by some type of small stone or gravel depending on what is desired or available.  I prefer crushed 1 inch lime stone.  It is the most economical option in my area.  Pea Gravel or some other type of small stone can work just as well.    The lime-stone or gravel is placed in the trench on top of the perforated Drain Pipe and filled all the way to the surface (ground level).   In some cases where the French Drain needs to be deep or is being placed in sandy soil, a special trench liner must be placed in the trench before the perforated Drain Pipe or the Gravel are installed.  This helps maintain the integrity of the trench over time.  It also increases the cost of the French Drain and the amount of time to install it.  I install a trench liner in a French Drain about 20% of the time.  Most of the time a liner in not needed.

A French Drain is designed to handle a large volume of water and cover a large area. The Drain is anyplace the trench goes. It has many applications and can be used in many situations.  It can be installed by itself or incorporated into a Drainage System with Surface Drains or Gutter Down-Spouts connected to it.
The main downfall of a French Drain is that they, for the most part aren’t very pretty.  They don’t look very nice in a yard once they are completed.
Depending on the area the French Drain is installed and the type of grass around the French Drain, will dictate whether grass grows over the lime stone.  Grass can grow up and through the gravel in the French Drain over time eventually covering the gravel.  This is OK.  It won’t have a measurable effect on the performance of the drain.
DONT COVER THE GRAVEL IN THE FRENCH DRAIN WITH DIRT.  THE FRENCH DRAIN WON’T WORK IF THE TRENCH IS CLOGGED WITH DIRT.  DON’T EVEN INSTALL IT IF YOU ARE GOING TO COVER IT UP WITH DIRT.

French Drain Installation In Downtown Oklahoma City

A little bit North of Downtown Oklahoma City,  Oklahoma Drainage and Sprinkler Repair installed a 6 inch French Drain between two businesses which were less than three feet apart.  The French Drain went between a Law Firm and a Tire shop.  Water was leaking through the walls of both businesses.  Gutters between the two establishments were dumping a huge amount of water.  We installed a 6 inch French Drain between the two.

It took a long time to get the dirt out of the trench for the French Drain.  It was a very tight fit.  We had to use a little red wagon to haul out the dirt for the French Drain and haul back in the crushed limestone for the French Drain.  It looked a little silly, but it was the only thing we could find that was narrow enough to fit between the buildings.  A French Drain that normally would take 1 day to install took three.

The French Drain had a Double Exit Point.  This means that once water entered the French Drain Pipe, it could run South to the street or it could run North to the alley.  To exit points greatly increases the water capacity for any French Drain.

Along the course of the French Drain, we connected two large gutters directly into the Drain Pipe.

Once in place, the French Drain eliminated all the water that was leaking into the two buildings.

Drainage Problem Solved!

French Drain Installation is a primary focus for Oklahoma Drainage and Sprinkler Repair

 

We install a variety of other types of Drains.  Our Drainage Systems may utilize: French Drains, Surface Drains, Channel Drains, Trench Drains, Basin Drains, and Sump Pumps.  In the past 21 years, we have installed French Drains to keep water away from home and business foundations, Surface Drains to keep water away from sidewalks and driveways,  Trench Drains, and French Drains to keep standing water out of flowerbeds and yards, and Sump Pumps to remove water from basements and outdoor low lying areas.

Oklahoma Drainage and Sprinkler Repair has been diagnosing and solving Drainage Problems since 1993.  Water has the ability to get into places around your home where you really don’t want it to be.  Some drainage problems are easy to solve.  Typically water enters the problem drainage area one way from one source.  The really tricky drainage problems occur when water enters the problem drainage area from multiple directions and from multiple sources.  Sometimes a secondary water source can’t be seen or identified until the primary water problem source is eliminated.

An example of this occurs when water is running into a problem area in an obvious way over the ground where you can see it.

Simple enough.

A drainage system is installed with a surface drain as the “intake” with drainage pipe running to an exit point.  Initially the water drains away and everything looks great.  The next day water is back and is all around the surface drain, but below the edge and it hasn’t rained at all, so no additional water ran over the surface of the ground to flood the area.  The primary water source was solved, ( The surface water run off ) but the secondary water source was not.  Which was sub-surface water, (ground water) running into the area.  A surface drain can’t drain “ground water.”  A French Drain should have initially been installed instead of a Surface Drain.  A French Drain can drain both Surface Water and Ground Water.

 French Drains as part of a Drainage System – 

Many times people use the term ” French Drain” as general name for a Drain used in or around your home.  French Drains are designed to move a lot of water over a large flooded area.  They are also designed to take water in on the surface of the ground or below the surface of the ground.  This is very important if the water coming into the flooded area is moving through the ground or coming up from underneath.  ” Sub Surface Water Movement.”  The picture below is not a French Drain!

A French Drain looks like this

A French Drain Can Handle Standing Water

A French Drain can take in water in a broad area.  It can move a much larger volume of water compared to a Surface Drain.  Also, it can move sub surface water moving into the area where a Surface Drain won’t move any water at all.

Surface Drains are designed to move surface water only on a smaller scale in confined areas.

Each solves specific drainage problems.  A Drainage System may use one or both together or even several using many types of drains.

Do you have standing water in a large area in your yard?  Typically this calls for a French Drain.  A French Drain is a great way to control standing water in a large grassy area.  It can also protect areas from flooding to a certain degree.  As long as the French Drains capacity to move water is not exceeded.  If the French Drains capacity is exceeded then water will stand in the drainage area until the rain stops and the drain has time to catch up.  A good way to prevent this is to install a bigger French Drain with a larger pipe.  The difference between a 3 inch French Drain and a 6 inch French Drain is huge.

Another way to beef up a French Drain is to connect gutter down spouts in front of the French Drain.  The water coming off the roof causes suction in the French Drain Behind it.  This greatly increases the French Drains ability to move water without increasing the size of the French Drain Pipe.

In the above picture no landscaping or special stone was used for the French Drain.  Initially it won’t look great, but in this case the French Drain was in an area that got a lot of sun.  The grass will spread and put out runners and eventually cover the French Drain.  This is a good thing.  It produces a “Thatch” filter on top of the drain and helps keep the drain from clogging and greatly increases the longevity of the Drainage System.  The trick is not to put dirt on top of the French Drain Gravel.  This is a big mistake and will reduce the effectiveness of the French Drain.  Just be patient and the grass will cover.  We had a customer that had success speeding up the growth process by sprinkling grass seed into the French Drain Gravel.

Since 1993 we have gained a lot of experience addressing drainage problems Drainage problems can be complicated.  The solution is not always clear to the untrained eye. Oklahoma Drainage and Sprinkler Repair has repaired or overhauled many french drains and drainage systems that were installed by, “weekend warriors, a brother-in-law, or a landscaping company that also installs drains.”  They all can install Drainage Systems, Just not very well.  We have  over 26 years of experience Diagnosing Drainage Problems.  This ensures that a Drainage System that we install won’t have Drain Pipes that are too small, or Surface Drains installed where French Drains Should be placed, or Exit Points that allow water to Stand and become stagnant.  The above examples are just three of many “Pit – Falls” that our experienced Drainage System Experts can easily avoid.

Surface Drain installed in Oklahoma City

Recently we installed a French Drain inside the court yard of a rest home in Norman.  We had several interesting challenges to overcome that were not typical for a French Drain Installation.  The court yard was in the center of the home and was a secure area for the patrons.  We had to put down painters tarps to run our wheel barrows over.  We took out 44 loads of dirt and brought in 52 loads of Crushed one inch lime stone for the French Drain.  Each trip was over a hundred yards from the trailer in the parking lot, in the front door, down the hall, making two turns along the way.  Each time we had to be escorted by security.  Needless to say, the installation of this particular drainage system took a while.In the above picture, the French Drain runs along the low area crossing all the areas where water would stand each time it rained.

When a French Drain is installed, a big mistake that is made by many people is to cover up the gravel with dirt.  This is a big mistake.  Basically it is ” Putting the cork back in the bottle.”  If the French Drain is in full sun and has a type of grass surrounding it that spreads on its own such a ” Tift” or “Bermuda” , Grass will grow over it and the French Drain will eventually disappear.  Grass covering a French Drain is a good thing if it grows across the drain without adding dirt.  The Grass thatch acts a water filter preventing clogging and extending the life of the Drainage System.

When a French Drain is in Full Shade, or the surrounding grass will not spread on its own, such as with Fescue,  other steps must be taken.  One option is to just leave it alone.  If you don’t mind how it looks, it will drain a large amount of water for many years.  Many times a French Drain can be a landscaping focal point.  They can be dressed up with all kinds of Rocks and Stones and Plants.

 

Just what is a French Drain?”  Many times people incorrectly

A French Drain can protect your foundation!

use the phrase, “French Drain,”  to apply to many different types of Drains that could be used in a Drainage System.  The term is widely used and many times incorrectly connected to “Surface Drains,” or “Channel Drains.”

A Surface Drain has a grate that sits on top of a basin.  The basin is underground.  A Drain Pipe is connected underground to an outlet on the Drain Basin Storm-Water Drains through the grate into the Drain Basin.  Once in the Drain Basin, water travels out of the basin through a Drain Pipe.  The Storm-Water continues downhill in an underground Drain Pipe to an exit point.

THIS IS NOT A FRENCH DRAIN!

A Surface Drain may come in many different shapes or sizes.  The Drain Grate may be round or square.  Here is a picture of a common Surface Drain.

A Channel Drain is a type of Surface Drain and many times is installed in concrete across sidewalks or driveways.

A French Drain is completely different from a Surface Drain.  A basic French Drain consists of a Perforated Drain Pipe in the bottom of a trench.  The Drain Pipe should have a neoprene sock around the Perforated Drain Pipe.   This is to ensure that the Drain Pipe does not become clogged.

French Drains Can Look Great!

Oklahoma Drainage and Sprinkler Repair recently diagnosed a Drainage Problem in  South Oklahoma City.  The Home owner had a sump Pump in their basement that was fed from a French Drain outside the Basement Wall.  The French Drain was 14 feet down along the Stem wall of the house.  The French Drain Pipe was cheap and had collapsed.  We brought in a Mini Excavator and dug up the pipe and replaced it with Durable ADS 4 inch perf/soc French Drain pipe.  In the end, we were able to dig up the pipe and Replace it.

Next we installed a new exit for the water by installing a curb fitting.

No more flooding in the customers basement.  A few weeks later our customer was able to lay carpet in the basement with no problems.

FRENCH DRAIN  CONNECTED TO GUTTERS

Many different types of Drains can be hooked together by one Drain Pipe.  The Drain Pipe then running to an Exit Point makes up a Drainage System.  One common type of Drain used in a Drainage System is A “French Drain.”  Many times a French Drain is installed close to a building foundation or in a low area next to a home or business.  This puts the French Drain in close proximity to Gutter Down Spouts.  Rather than have water come off the roof and out the Down Spout and on to the ground below, many times it is much better to tie a Gutter Down Spout Directly into a French Drain or near by Drain Pipe depending on the Drainage System Design.   Connecting The Down Spouts Directly into a French Drain is much  more efficient and causes suction to occur in the French Drain.  Connection of Gutter Down Spouts to a French Drain makes the Drainage System work better.
