Overview

What you should know about bathroom & kitchen waterproofing

Bathrooms and kitchens are wet every day: water on the floor, splashes on walls, and drains and pipes penetrating the slab. Any untreated point, especially around the drain or at the floor-wall junction, becomes a path for water.

We apply the waterproofing as a continuous layer over the floor and up the walls, seal drains and pipe outlets with reinforcement pieces, then flood-test before the tiler starts.
