FRENCH DRAINS PROTECT FOUNDATIONS

When homes are sold many times a “Structural Engineer” is required to inspect a home.  Many times, when water damage has occurred a Structural Engineer will recommend a French Drain Installation to protect foundations, Driveways, and Sidewalks.  It can protect them from further water damage.

A French Drain protects foundations, and anything else made of concrete when installed correctly.

 

 

 Standing water can cause many types of property damage ranging from foundation problems to cracked sidewalks and dead plants and shrubs.  If you have need of French Drain or Surface Drain, give us a call.  We provide free estimates for all of central Oklahoma.

French Drain in Edmond Oklahoma

French Drain in Edmond Oklahoma

The most common Drain that we install is the French Drain.  This is because the French Drain is versatile.  It can handle Surface Water Problems or Underground Water Problems (sub-surface).

A huge mistake that many people make is assuming that water gets to a Problem Drainage Area by flowing over the surface only.  For example, if water is flowing downhill underground toward your home’s foundation, the only way to stop or intercept it is with a French Drain.  Water can flow laterally into a perforated French Drainpipe.  It is then diverted away from the Problem Drainage Area to an Exit Point.

 

French Drain or Surface Drain

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

A trench is dug that is slightly wider than the French Drainpipe that is being used.  There are several sizes of French Drainpipe.   Three Inch, Four Inch, and Six Inch are the most common sizes of French drainpipe.

Gravel Or Limestone

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 limestone.  It is the most economical option in my area.  Pea Gravel or some other type of small stone can work just as well.

The limestone or gravel is placed in the trench on top of the perforated Drainpipe 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 Drainpipe or the Gravel are installed.  This helps maintain the integrity of the trench over time.  Pipe running to street form French Drain in back yard.

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.

Downfall of a French Drain

The main downfall of a French Drain is that they, for the most part isn’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 limestone.  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 French Drain.
In some cases, thick grass growing up through the French Drain will create a natural “Thatch” filter.  This makes the French Drain invisible.  The trick is to allow the grass to grow over the French Drain Gravel without covering it up with dirt.  Grasses such as Bermuda which grow well in the sun will put out runners and new roots and will grow up and through the French Drain.  This will not affect the performance of the French Drain.  The problem is that sometimes depending on the type of soil involved, it may take a long time to completely cover up the French Drain.  Sprinkling grass seed down in the gravel will speed up the process.

Don’t Cover a French Drain with Dirt!

DON’T 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.

If you install a French Drain in a sunny area, you can:

                                         A.  Leave the French Drain as-is and allow grass to grow over it in time.
                                         B.  Add grass seed directly to the French Drain gravel with (Light Hand Watering) to speed the growth process
                                         C.  Leave the French Drain as-is but decorate it with steppingstones and landscaping rocks (leaving large cracks between stones to allow water to get into the French Drain,

If you install a French Drain in a shady area, you can:
                                        A.  Leave the French Drain as-is, it will work well and look as it did for many years.

                                        B.  Leave the French Drain as-is but decorate it with steppingstones or landscaping rocks.  Many French Drains are hidden under rock walkways.

French Drain, Dry Floor Vents, Keeps Water out of AC Ducts.

 

A FRENCH DRAIN CAN KEEP WATER OUT OF AIR CONDITIONING DUCTS

 

French Drain Installation can prevent water from getting into your air conditioner floor ducts.

 

 

A common Drainage Problem

for people in Central Oklahoma is ground water seeping into floor air conditioner  ducts.  This can cause very costly damage to a home or business.  Water-proofing Ducts, or even worse, trying to remove mold from duct work can cost big bucks.   Structural Engineers typically recommend French Drain Installation to keep water out of ducts.

French Drains catch and remove sub-surface water that is traveling underground toward a foundation. It is intercepted by the French Drain before it can seep under the building in question.   Because this water is not usually seen, it may not be taken into consideration when diagnosing drainage problems.  Surface Water traveling to a problem area is obvious as it flows on the surface in plain sight.

We have 32 years of experience Diagnosing Drainage Problems.  We always check for sub-surface water flow into any Problem Drainage Area.  Again, French Drains are intended to handle water moving both underground and above ground.

 

French Drains

can also be used to remove water that is standing in a large area such as up against a foundation or along a fence.  French Drains don’t do so well in tight small areas.  These areas are best suited for a Surface Drain with a grate.  Many times, we install French Drains along foundations after a homeowner has spent large amounts of money on foundation repair.

Several Foundation Repair companies and Duct waterproofing companies recommend Oklahoma Drainage.   Typically, we install a French Drain by itself or as part of a Drainage System  after they have completed their repairs to the foundation or duct work.

Oklahoma Drainage provides quality service for central Oklahoma.  If you live in Norman and need a French Drain, or if you live in Oklahoma City and want a Channel Drain installed across your driveway, give us a call.

We have installed Drainage Systems and French Drains in:  Oklahoma City, Edmond, Moore, Midwest City, Norman, Yukon, Mustang, Del City, Blanchard, Newcastle and all surrounding areas.

Recently we installed a French Drain in Norman.

Our customer had water running down the hill from his neighbor’s Sprinkler System into the North wall of his house.  Over time the ground became saturated and water seeped under the wall and into his floor air conditioning vents.

We installed a 4-inch French Drain along the North wall of his house to provide a barrier to the continuous water flow.  In a few days the moss that was growing on the side of his house began to die from lack of water.  A Duct company came in and cleaned out is vents.  The French Drain removed the surface and sub surface water that was flowing into his home.   Problem solved.

IT MAY TAKE A FEW HOURS FOR US TO GET THERE BUT WE WILL COME TO HELP.

 

One Common problem is that they continue to run and won’t shut off.  In most cases this is a problem with a sprinkler valve that has “Stuck” in the on position.

This can be temporarily solved by shutting of the Emergency Shutoff Valve.  The problem is that some sprinkler systems don’t have one to turn off or if they do the homeowner doesn’t know where it is.

It may be on the back-flow valve which may be located on the side of the house under a big plastic fake rock.

Many sprinkler systems in Oklahoma have them. (50 % ?)  Under the plastic rock is a back-flow valve with two shut off handles.  Usually, they have blue or green or tan handles.  Turn one of the handles and it should shut off the water to your sprinkler system.

Other times the Emergency Shutoff Valve is in a box in the ground out by the curb near your water meter.  The valve box will have a green lid.  Sometimes they are difficult to open.  Many times, I had to pry them open with a flat head screwdriver.

 

Inside the valve box is a plastic handle that can turn off the water to the sprinkler system.  It can be blue or red or grey in color.

Many times, the valve box will be full of dirt, and you can’t turn or even see the handle until some of the dirt has been dug out by hand.

 

Water might be shooting up in the air somewhere on your property.  This can be caused by a broken sprinkler pipe or sprinkler valve.

SHUT OFF THE SPRINKLER WATER IF YOU CAN AND GIVE US A CALL.

Recently

Oklahoma Drainage and Sprinkler Repair Installed a French Drain as part of a Drainage System in Mid-West City Oklahoma.

Our customer had a back porch Sunroom.  Every time he had a hard rain, Water would run in one door and out the other.  An indoor creek across his Sunroom.

French Drain protects sidewalk

French Drain keeps water off of sidewalk

We installed a French Drain in front of the South Door.  It was 26 feet long and ran from a gutter downspout which it was connected to,  in front of the South Door and along the house covering the entire “Low” Area.  Then we connected 4-inch ADS Solid Drainpipe to the French Drain and ran down hill around the corner of the house to the street.

Once the 4 inch solid drainpipe was connected to the French Drain and the two gutter down spouts, a pop-up emitter was installed to release the water at the street.

The next step

was to cover the drainpipe with dirt and put the sod back in place on top of the pipe.   There was about 8 wheelbarrows of dirt left over that was displaced by the drainpipe and the French Drain.  The extra dirt was scooped up and hauled away.

While installing the drainage system, it was necessary to move two sprinkler heads that were in the way of the drainpipe installation.  This was no problem.  Installing drainage systems and French drains for folks who have a sprinkler system is very common.  Moving Sprinkler heads or pipes sometimes is necessary.  We always leave the sprinkler system in complete working order and we discuss any changes in the sprinkler system with the customer before we do it to make sure that everyone is on the same page.  In most cases the customer can’t tell that we made any changes to the sprinkler system at all.

Harsh weather

in Oklahoma seems to become more common.  In 2013, Norman Oklahoma had 4 inches of rain in two hours.  That’s the most rain in a short time that I can remember.  Storm-Water runoff can cause damage to all types of property and buildings.  Water getting inside your house is never a good thing.  A Drainage System that utilizes a French Drain can help.

Drains can protect your home and property from water damage.

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.

Complex Drainage System

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 Drainpipe that is connected to the Drain.

Simply put,

a Drainage System is one or a group of underground Drainpipes 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 Drainpipe to move the water away from the Drain, and an Exit Point for the water to be released out of the Drainpipe.

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 Drainpipe required for the Drainage System.  A good rule to follow is, “If in doubt, install a larger Drain and Drainpipe.”  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 Drainpipes —

3 inch, 4 inch, and 6 inch French Drains —

French 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

Determine Drainpipe Size

Once the type and number of drains is determined and what size Drainpipe 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 Drainpipe 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 Drainpipe.  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.

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.

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.

Surface Drain and Drain Pipe

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

Channel Drain

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.

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.

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 thedrain.
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.

3 inch, 4 inch, and 6 inch Drain Pipes —

3 inch, 4 inch, and 6 inch French Drains —

French 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.
