French Drains
French drains are versatile drainage tools. HSRC helps homeowners understand common designs.
French drains use perforated pipe in a gravel bed to collect and move water. They can be installed inside a basement perimeter, outside along foundations, or in yards to move surface water.
Key Takeaways
- Interior perimeter systems collect groundwater.
- Exterior French drains manage surface or foundation water.
- Discharge must go somewhere useful.
- Silt and roots can clog drains over time.
- Design and slope matter.
Overview: French Drains
Interior systems often feed a sump. Exterior systems can discharge to daylight where terrain allows.
Poorly designed drains can fail or move water to the wrong place.
What Homeowners Should Consider
