French Drain Trench Liner – Pipe Filter

Oklahoma Drainage and Sprinkler Repair – 405 203 9419

A Trench Liner is a semi-permeable fabric that lets water pass through it into the French Drain.

It is placed in the empty French Drain Trench before the French Drainpipe or Gravel are installed.

The Trench Liner’s purpose is to Maintain the integrity and functionality of the French Drain without allowing Debris to enter or clog the Perforated Pipe.

Debris typically is Mulch or Grass Clippings.  It can even be sand or dirt.

Installing a Trench Liner is the Key to ensuring that the French Drain will work correctly for a long time.  I have installed French Drains in 1993 that still work.

The white fabric in the picture above is the Trench Liner.  The black fabric around the pipe is the Pipe Filter.  They work together to make the French Drain last.

Many “Weekend Warriors,” or Landscape Companies that don’t specialize in French Drain Installation, skip installing Trench Liner and Pipe Filter.   It may save a small amount of time or money.

Big mistake!

In a short amount of time the French Drain will clog up and quit working.

A French Drain is one part of a Drainage System.

Drainage Systems have three parts, an “INTAKE,’ A “TRANSITION,” and an “EXIT.”

A French Drain takes water in through a perforated pipe.  This is the, “Intake,” portion mentioned above.  The French Drain is how the water gets into the Drainage System.

The Perforated Pipe is placed at the bottom of the Drainage Trench.

The French Drain takes in water and places it into the Drainpipe.  The Drainpipe is in a Drainage Trench that crosses a large area that has water problems.
The French Drainpipe is connected to a solid drainpipe.  The water moves through the French Drainpipe into the solid Pipe.  The Solid Drainpipe is the TRANSITION.  It takes the water where you want it to go.

The EXIT is the place where water leaves the Drainage System and goes on its way.

The need for Drainage Systems is increasing in Oklahoma.  During heavy thunder storms,  homes and business need a way to drain water away.  Storm water can cause many kinds of damage.  Here are just a few:

1.  Driveways and Sidewalks can crack and deteriorate

2.  Foundations can crack move or shift

3.  Vents and ducts can fill with water

4.  Mold can be allowed to grow

5.  Trees and Plants and grass can be damaged or drown

Too much water is never a good thing!

Oklahoma Drainage can quickly diagnose your Drainage Problem and provide a free quote for a Drainage System.  With twenty years of experience, we realize that Drainage Problems may be very complex and difficult or very straight forward and simple.  Every Drainage Problem is unique to a certain degree.  Don’t kid yourself,  Experience Counts!

What is the Primary Water Problem?

We take many things into account when providing a Drainage Diagnostic for a Customer.  We determine:

1.  What is the Primary Water Source to the problem?  Where is the water coming from?

2.  Is there a Secondary Water Source?  Other Places that water may be coming from.    All Drainage Problems have more than one source!

3.  How many Subsequent Water Sources are present?   Some complex Drainage Problems have many water sources.

4.  What exit points are available for gravity to move water away from the problem area?  Where are we trying to take the water to, and how is it

going to be released?  Is more than one exit point possible to increase capacity?

5   How much water must be moved?  What Size Drainpipe is necessary to lessen the chance of being overwhelmed by flooding?    This is a tough

consideration.  (Larger Pipe – Larger Cost to Install)

These are just a few of the considerations for any Drainage System Diagnostic.

The Drainage System shown in the three above pictures consisted of the following:

Three Gutter Downspouts in the front yard were connected to 4-inch ADS solid Drainpipe with Large Drainage Gutter Connections.  Three lateral 4-inch Pipes were run from each gutter to one outflow pipe moving the water to two exit Pop Up Emitters. One of the Drainpipes ran under the sidewalk to reach the Exit Drainpipe.

This Drainage System had two exit points.  One Pop-Up Emitter was on the edge of the driveway in the front yard.  The other Pop-Up Emitter was installed in the back yard near the property line.  Two exit points allows for a much larger Water Drainage Capacity.  (During Heavy Rains the Drainage System Can Move More Water Faster)

The back yard Exit Pipe

then connected to 55 feet of 4-inch French Drain that was installed along the SW corner of the house.  The French Drain provided a protective barrier for that room of the house where water had previously been leaking into the floor vents.  Two Gutter Down Spouts were also connected in the back yard to the Drainage System.

A few days later a heavy rain came in.  No water stood on the sidewalk near the front door, and nor water seeped into the floor vents in the back bedroom.

French Drain Installation

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.  The Drainpipe should have a neoprene sock around the Perforated Drainpipe.   This is to ensure that the Drainpipe 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 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.  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 Every time!

Large Water Volume

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 Downspouts connected to it.
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 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.

DECORATIVE STONE CAN BE USED TO COVER A FRENCH DRAIN AND THEY LOOK GREAT AND LAST A LIFETIME.

French Drains Can Look Great!
