A French drain is a channel lined with stone or solid material, possibly with a perforated section, designed to collect surface drainage water from below the earth’s surface. Drainage systems that use French drains are relatively inexpensive and easy to install if you are prepared and have the appropriate materials. They can be used for many different applications where you need to channel ground water away from foundation walls or other structures. For this article, we’ll look at some common uses of a French drain along with some general guidelines for selecting a French drain system.
The best type of French drain is made of earth or stone and perforated to channel away surface runoff. There are two basic types of French drains. One types are actually part French drainage system, the other part of a trench. A French drain trench is simply a long, narrow trench filled with loose soil or gravel of one type of material and perforated for draining away surface water. Sometimes the trench is lined with soft soil to hold in the weight of the debris.
The primary materials used to make French drains are: rubber (either polyethylene or epoxy), metal mesh, stone, or thick aggregate. Some French drains are constructed so that they attach to a post. These posts are usually not made of stone but may be welded together with epoxy or aluminum.
French drains can be installed in a variety of ways. You can dig a ditch that is lined with gravel several inches deep and wide enough to accommodate the French drain. The French drain then travels through the slope toward the outlet. Some drainage systems are built inside the walls of a home, while others are installed just outside the wall.
If a French drain is used inside a wall, first the dirt excavated from the wall is pumped back into the ditch. Then the pvc pipe or any other pipe is inserted where the French drain is to be located. The French drain then attaches to the pipe. This method eliminates the need for digging an excavation, lining the pipe with dirt, and then pouring the surface water onto the soil. All of this work has the benefit of creating a waterproof surface along the exterior wall of the home.
Once the French drain filter fabric is in place inside the wall, another layer of soil is installed around the outer edge. This second layer provides additional footing on which to spread the concrete mix. After the concrete mixture has dried, it is poured into the inlet. After the inlet is completely dry, the French drain filter fabric is removed and the trench is lined with PVC pipe.
Today’s drainage systems are much more sophisticated than the original French drainage systems that date back centuries ago. Modern French drains incorporate hydrostatic pressure in their design that requires no ground source for the water to drain. A French drainage system consists of a number of different elements such as French drain material, French drains, a pressure tank, and an inlet grate or French drain opening. A French drain is another way of saying a trench in your yard.
A French drain kit is a fantastic option for any homeowner who wants to avoid digging and putting in a foundation footer drain for their yard. If you encounter drainage problems in your yard that are causing you a lot of time and frustration, consider installing a French drain in your yard. You will eliminate a large amount of time and frustration from dealing with drainage problems. Installing a French Drain will also increase the value of your home and add curb appeal to your yard.
