Oklahoma City French Drain Specialist, Norman, Moore, Edmond

Too much of anything is never good, especially water.  Standing water can cause damage to sidewalks, driveways, and foundations.  Water can also seep into floor vents and under homes.  During a hard rain water can even run inside homes and business when Drainage is poor. If water is causing damage to your home or business, CMG can help.  We provide free estimates up to 100 miles from Oklahoma City.

Installing French Drain along foundation of home in Norman

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 of French Drain Pipe.   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 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 some times 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 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 stepping stones 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 stepping stones or landscaping rocks.  Many French Drains are hidden under rock walk ways.IF YOU NEED WATER DRAINED AWAY FROM YOUR HOME OR BUSINESS CALL CMG.  405-226-0629  CMG Sprinklers and Drains installs all types of Drainage Systems and French Drains.

rain freeze sensor

If you own a sprinkler system or are considering installing one, you should consider a RAIN/FREEZE SENSOR.  A RAIN/FREEZE SENSOR turns off your sprinkler system when no one is available to turn it off.  For example: if you are on vacation, and it rains a lot while you're away, your RAIN/FREEZE SENSOR will turn off the sprinkler system and turn it back on again when it is dry enough to irrigate again.  The RAIN/FREEZE SENSOR will also turn off the system it gets too cold.
CMG also designs and installs drainage systems.  If you have water standing in your yard after a thunder-storm or if your sidewalk turns into a moat after a hard rain you should consider a drainage system.  CMG has experience with many different types of drainage problems.  We utilize: French Drains, Surface Drains, Channel Drains, Basin Drains, Trench Drains, Basement Drains, and Sump Pumps.

My name is Blane Callen. I have owned and operated CMG Sprinklers and Drains since 1993.  I take great pride in my work.  The Letters "CMG" stand for the first letter of the first name of each of my children.  ( Chance, Melissa, Garrett )  = CMG
I have amassed a great deal of experience designing and installing sprinkler systems,  repairing sprinkler systems, and designing and installing drainage systems.  Like all things in life, I have made mistakes, but I have learned from them.  As a result I get calls from time to time from other sprinkler and drainage companies that have run into a problem that they can't handle.  I am always glad to help.


I usually don't take money up front for Sprinkler Installation, Sprinkler Repair, or Drain Installation.  I prefer that the customer pay me when the job is complete and they are happy with the work.  In a few cases on very large jobs I request a draw or outlay for parts.  The parts are delivered from my supplier to the address where the job is being done and equal the amount of the draw.  The parts stay on the premises until they are installed.
