Foundation Waterproofing Report

For underfloor slabs on grade in a below grade condition, Division Seven 1st performs a site review to verify the subsurface drainage has been put in properly. We then install a pre-applied waterproof membrane system which forms a chemical bond to the concrete when it is placed. Below grade foundation walls are cleaned and primed.

Decks Report

Waterproofing a deck over a living space requires one vital result - no leaks. Division Seven conducts a site review and visually inspects all deck substrates prior to installing our waterproofing. We apply multi-coat, 2-component urethane waterproofing systems that have excellent durability and waterproofing characteristics.

We use the most current, but demonstrated effective waterproofing materials. New products, and new forms of established products, are carefully evaluated by our Production Managers to be sure the real applications are going to be successful on the job. Call 707-224-9599 for a quote!
