How Does a French Drain Work?

A French drain is a drainage system installed around a building’s foundation.

It collects water that builds up near the walls and directs it away to an area where it will not cause infiltration issues inside.

Installing this system helps prevent foundation damage caused by moisture.

Which Type of French Drain Should You Choose: Exterior, Interior, Rigid, or Flexible?

  • The exterior French drain is the most common. It is installed around the outside of the foundation and works well for most homes and soil types (clay, sand, gravel).
  • The interior French drain is mainly used when exterior installation is not possible (limited space or renovations). It captures water that has already entered the basement.
  • The rigid drain (usually perforated PVC) is recommended for clay or unstable soils because it resists pressure and ground shifting more effectively.
  • The flexible drain (corrugated polyethylene) can be suitable for small projects or softer soils, but it is less durable in clay or rocky conditions.
