Why is My Basement Damp?

Unlike above-ground walls, basement masonry is under constant "hydrostatic pressure." This means groundwater is actively pushing against your home's foundations. Without a professional waterproofing system, moisture will eventually find its way through even the smallest cracks or porous bricks.

Hydrostatic Pressure

Ground water being forced through the walls and floor.

Capillary Action

Moisture "wicking" through porous brickwork or stone.

Lack of Ventilation

Causing condensation and black mould in poorly aired cellars.

Sump Pump Failure

If an old drainage system is no longer functioning.

The Two Primary Methods of Waterproofing

METHODHOW IT WORKSBEST USED FOR...
Type A: Tanking (Slurry)A physical, waterproof coating applied directly to the internal walls to block water.Smaller cellars, solid masonry, and preventing "damp smells."
Type C: Cavity DrainageA studded membrane that allows water to flow behind it into a hidden drainage channel and sump pump.Larger conversions, high-water-table areas, and creating habitable rooms.
