Waterproofing in Cupertino, CA

Cupertino's housing stock includes a large number of homes that have been substantially remodelled or rebuilt, which means we are often working alongside a general contractor on an active project rather than repairing an old failure. Getting waterproofing into the right point in the schedule — before backfill, before the topping slab, before tile — avoids opening finished work later.

Under-tile waterproofing is a frequent request on these projects. Showers, balconies, and terraces all need a bonded membrane between the slab and the tile assembly, with reinforced detailing at corners, curbs, and drains, and a flood test before any tile is set.

Epoxy garage floors are the other steady call. Every slab is diamond ground rather than acid etched, moisture tested before coating, and repaired at cracks and pits so the finish has a sound surface to bond to.
