Waterproofing service in Riverside, CA

A large portion of Riverside's single-family homes were built between 1940 and 1999 using mortar-bed shower floors that were originally waterproofed with hot mop. When contractors open those showers during a remodel, replacing the pan with the same hot mop method keeps the system consistent with how the home was built. It also provides a seamless waterproof barrier that protects the slab or wood subfloor below.

Yes. Hot mop waterproofing works on both slab-on-grade and wood-framed subfloors, which are both common in Riverside's housing stock. The mortar pre-slope is built first to direct water toward the drain, then the asphalt-and-felt layers are applied over it to create a watertight membrane. This method conforms to the existing shower footprint regardless of the foundation type.

Riverside's hot, dry summers cause building materials to expand and contract repeatedly. Grout lines and tile can develop micro-cracks over time, allowing water to seep through to the shower floor below. A hot mop pan creates a seamless, flexible asphalt membrane that stays watertight even as the surrounding materials move with temperature changes.

Yes. Hot mop is installed after the mortar pre-slope is set and before tile goes down. Contractors typically schedule the hot mop crew between those two phases. Because the asphalt cures quickly, tile work can usually follow without a long delay, keeping the remodel timeline on track.
