Foundation Waterproofing in Vancouver, BC

With the foundation wall excavated, the wall itself can be sealed. This is the highest-value moment in any drainage project, and it is the reason waterproofing and drain tile replacement are so often quoted together. Vancouver's pre-1970s housing stock still runs on original clay or concrete perimeter drain tile, and heavy winter rainfall on dense city lots makes full-perimeter replacement one of the most common drainage jobs in the city.

Systems used

Spray-applied damp-proofing, self-adhered rubberized membranes, and dimple board drainage mats that direct water down to the new drain tile.

Crack and cold-joint repair

Polyurethane or epoxy injection seals structural and non-structural cracks before the membrane goes on.

Why it lasts

An exterior system stops water at the outside face of the wall, which protects rebar, prevents efflorescence and keeps finished basements dry.
