How French drains work
A French drain is a trench filled with gravel and a perforated pipe, wrapped in a membrane, that collects water and carries it away.
We position drains to intercept water, connect them to a suitable outlet and reinstate the surface.
In Forest Hill, French drains along the house wall can stop water pooling against it.
