Waterproofing

Blindside membranes are installed against shoring or lagging before the foundation wall is poured, for sites where there is no room to work on the outside face of the wall after the pour.

Where the excavation allows access to the outside face of the foundation, the specified membrane, protection and drainage board are applied directly to the wall before backfill.

Crystalline systems are applied to or mixed into concrete as specified and react with moisture in the concrete to reduce water passage through the substrate.

Podium slabs, plaza decks and other horizontal surfaces over occupied or parking space receive the specified membrane system, detailed at drains, curbs, penetrations and terminations.

Traffic-bearing coating systems for parking decks, ramps and similar surfaces are applied to the specified build-up for the expected pedestrian or vehicle traffic.
