The Importance Of A French Drain System

French Drain System

French Drain System | Texas tends to have a lot of rain, when the rainy season comes, especially in Dallas and Houston area. Some houses tend to get their yard soggy when it rains, and when that occurs a French drain system is the solution. In the following paragraphs, we will explain how they work, when to use them, the different types of french drain.

Water tends to find the easiest route, and it’s usually downhill. With that in mind, comes the basic concept behind a French drain system. Installing a pipe that diverts water away from your houses, with a lightly sloped trench filled with round gravel is the concept of a proper designed French drain system.

Oh, in case you were wondering, the French drain system name isn’t name after the county. It was name after Henry French, a judge and farmer in Concord, Massachusetts, who promoted the idea in an 1859 book about farm drainage.

French Drain System At Work

A French drain provides the homeowner an easy channel for water to flow through to eliminate an overflow of water in the yard. French drain system works by the process of water running into a gravel-filled trench, then into perforated pipe at the bottom of the trench. The water will be emptied into a safe distance of the home, as the water travels freely through a pipe.

By sloping the trench bottom about 1 inch for every 8 feet, it will go into the direction you want the water to flow. Areas where the water can be diverted to include, but not limited to:

  • Drainage ditch
  • Dry well
  • Low-lying area of your property
  • The street

When Do You Need a French Drain System

  • The water is getting into your home
  • When a building is on a retaining wall on a hillside

Surface Water Problem

The solution for surface water problem is to install a shallow French drain system. The shallow French drain is also known as a curtain drain, as it extends horizontally across your home. I will be places on the uphill of the area that needs to be dry out. It will capture water and push it around the wet spot. The common size for the shallow French drain system is about 2 feet deep and 1.5 feet across.


Retaining Wall on a Hillside

When it comes to installing a retaining wall, you must add a French drain system behind the first stacks of stones. If it’s not done properly, it will lead to water that is going down the hill will build up behind the wall. You many use some cloths to avoid any clogging with silt.
