What Is a French Drain?

A French drain is a type of in-ground drain system that moves water through the soil and away from the foundation of a structure to prevent damage and flooding. French drains are common in areas where precipitation can be heavy, and in homes with basements or crawl spaces that flood regularly.

To install a French drain, the soil is removed and replaced by a perforated PVC pipe. Water flows into the pipe as the ground becomes saturated, then the water is transported through the drain and away from the structure. The soil-retention fabric prevents the drain from filling with soil, which stops sinkholes from forming in the area and also prevents the drain from clogging.

Components of a French Drain System

  • A trench is dug deep into the soil to collect the water that exists in the soil around the perimeter of the structure.
  • The trench is lined with filter fabric to prevent soil from entering the drain.
  • A rock field is used to allow for water flow to the perforated pipe. The rock field also creates a barrier that prevents soil from entering the pipe.

Where Are French Drains Installed?

French drains are typically installed around the exterior of the building, home or structure, because this is where water can penetrate the foundation and cause flooding and other damage. Sometimes French drains are installed in low points in the lawn when large puddles tend to develop following rain. This prevents boggy water from damaging plants and also makes the lawn more useful to homeowners. Some French drains are placed inside the house to protect basements and crawl spaces that naturally fill with water.
