French drain

Ask a question

Traditional French drains have been used to help manage water around properties and to prevent ground and surface water from penetrating or damaging building foundations since the 1920's.  Over the last 20/30 years however, they have also been used to assist with basement waterproofing projects and to help keep water out of a newly finished cellar or basement conversion.  It has for years been an excellent solution, but it is not without its problems.

How a French drain works

A French drain works by burying a pipe around the outside of the footing or bottom of the walls. Small, crushed stones are then placed around the French drain and the soil that is displaced when digging the hole is then pushed back on top of the French drain. The French drain then works by collecting the water that gets through the stone and into the drain. The water is then directed safely away from the basement or cellar.

Modern French drains

In recent years, drainage systems have been developed which are far more effective and are not prone to the problems associated with traditional French drains. Each of our basement drainage systems are designed to address a different problem that you may be facing in your property. These basement drainage systems are installed inside the property as opposed to on the outside and concentrate on managing the water rather than preventing it getting in.  To find out more, read the information links below.

Water Guard - the new French drain

Water Guard

The Water Guard drainage system is installed along the walls of a basement along with a membrane on the wall. This ‘catches’ all the water as it enters a basement or cellar and directs the water to a sump pump for safe removal.

DryTrak - a modern French drain system


The DryTrak drainage system is the only basement drainage system that can be used if the wall and floor joists are joined up. The water enters the DryTrak drainage system and then is directed to a sump pump for safe removal.
