    How Does a French Drain Work?

    French drains are typically placed around the exterior of the foundation and are used to divert water from standing or pooling that can cause structural damage. Similar to a roof gutter where rain water is directed to a downspout, French drains manage surface water at ground level. The simple design consists of a sloped trench filled with gravel and perforated pipe. As rainwater and other surface water soaks into the ground, it is filtered through the gravel into the pipe and channeled through the trench to a collection point away from the foundation. Occasionally, an existing system may fail, allowing water to infiltrate the foundation. In this instance, an interior French drain system may be installed under the basement floor. The principal is similar to an exterior system with a sloped trench, piping and gravel. The water is re-routed to a sump pump and then transported through pipes to an exterior storm sewer.

    How to Install a French Drain?

    Step 1: Dig a trench

    A trench should be at least 12 inches wide and 18 to 24 inches deep. A recommended slope of one inch for every eight feet should be used to direct water away from the foundation. It should be positioned below floor level if being used to prevent basement moisture or a wet foundation.

    Step 2: Pour the gravel

    Gravel placed in the bottom of the French drain acts as a natural filter. It allows the water to drain freely without clogging from leaves, branches or other organic material. The best gravel choices are granite or river gravel as they won’t break down over time. The gravel should be one-half inch to one inch in size and line the bottom of the trench to a depth of two or three inches. It should also be washed to prevent dust and particles from blocking water flow.

    Step 3: Lay the pipe

    There are two types of pipe that can be used for this purpose. Rigid PVC pipe with pre-drilled holes is more durable and can be snaked or pressure cleaned. Flexible pipe with slits is easier to work with and less expensive. Before laying the pipe, cover the stone or wrap PVC pipe with landscaping fabric to prevent weed and root growth and obstruction. PVC holes should also be oriented downward to allow water to flow from below and prevent clogging. Another suggestion for future maintenance of PVC piping is to attach a joint that remains above ground and accessible as a clean-out.

    Step 4: Backfill the trench

    A few options are available for covering the pipe. You can cover the pipe by filling the trench with gravel to grade, use a combination of gravel and course sand, or gravel and dirt with sod. The latter will be utilized to conceal the French drain completely; while the other options will allow for easy access or maintenance.

    As with most large projects, planning is critical to be sure everything runs smoothly. Some things you need to do before starting construction are:

    • Contact the local utility companies to have all underground lines located and marked.
    • Determine a location for leftover dirt. Most of the soil removed for the French drain trench will not be needed.
    • Start the trench at the end of the drainage system so adjustments can be made to the slope if an obstruction is encountered along the path.
