What Is a French Drain?
A French drain is a simple but highly effective drainage system designed to redirect water away from a building’s walls and foundations. It usually consists of a gravel-filled trench with a perforated pipe, which allows water to flow away from the property and into a safe drainage area.
For homes in Chester, where heavy rainfall and clay soils can keep moisture sitting against external walls, French drains are an excellent way to prevent damp before it starts.
How French Drains Prevent Damp
When rainwater collects around the base of a property, it can penetrate external walls, causing lateral damp and damage to internal finishes. A French drain solves this by:
✅ Redirecting excess water away from walls
✅ Relieving hydrostatic pressure in the soil
✅ Keeping external ground levels dry near the property
✅ Reducing the risk of moisture ingress into basements and ground floors
When Is a French Drain Needed?
Consider installing a French drain if you notice:
-
Persistent damp patches on lower walls
-
Water pooling around your home after rainfall
-
High external ground levels against the house
