Tuff-n-Dri and Warm-n-Dri Waterproofing in Ottawa

Tuff-n-Dri is a spray-applied flexible polymer-enhanced waterproofing membrane that seamlessly bridges foundation settling cracks and seals out water penetration providing a minimum of 40 ml of protection when cured. When used as a two-part system, Warm-n-Dri board assists in drainage, reduces interior condensation and channels unwanted water to the weeping tile.

Some builders in the Ottawa area use this product as an upgrade product, while others use it as their standard to ensure that the houses they are selling are waterproofed below grade.
