Oklahoma is famous for it’s powerful thunderstorms and heavy downpours. Storm-water runoff causes a variety of DRAINAGE PROBLEMS for Home and Business owners.

This front yard needs a french drain!

DRAINAGE PROBLEMS come in a wide variety of forms. You might have water standing in your backyard after a thunderstorm. Water from your gutter-downspouts may be turning your sidewalk into a “Moat.” Or, worst of all, Standing Water may be seeping into your home. WE can help!

Drainage solutions sometime require one or several types of drains to solve the problem. Oklahoma Drainage and Sprinkler Repair has been successfully solving DRAINAGE PROBLEMS since 1993. We can quickly diagnose your DRAINAGE PROBLEM and design a DRAINAGE SYSTEM to solve your DRAINAGE PROBLEMS. WE UTILIZE: FRENCH DRAINS, SURFACE DRAINS, CHANNEL DRAINS, BASIN DRAINS, TRENCH DRAINS, BASEMENT DRAINS, AND SUMP PUMPS.

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, does water seep into your foundation and duct work after a thunderstorm.  Theses are just a few of the Drainage Problems that Oklahoma Drainage can help with.

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 BasinStorm-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.  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.

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

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.
