A common question among some of our customers is, “What are French drainage systems?” A French drain is the most common type of outdoor drainage system. It directs water to a drain rather than dispersing it within the landscape.

What are French Drainage Systems?

French drainage systems provide an easy channel for water to flow through. Water runs into a gravel-filled trench, then into perforated pipe at the bottom of the trench. The water then empties a safe distance from your house.

With a French drain, there’s a slope on the trench bottom of about 1 inch for every 8 feet in the direction you want the water to flow. Depending on your property, you can divert the water to one of the following:

  • A low-lying area of your property
  • A drainage ditch
  • A dry well
  • The street
