Waterproofing in Redwood City, CA

Redwood City's mixed-use and multi-family growth has produced a lot of podium construction — occupied space directly beneath a plaza or courtyard level. That assembly only works when the between-slab waterproofing is detailed correctly, because once the topping slab is poured, the membrane is inaccessible.

We install hot fluid-applied and sheet systems on these decks with electronic leak testing before the topping goes down, and we coordinate directly with the concrete crew so terminations, drains, and penetrations are sequenced right the first time. On existing buildings where a podium deck is already leaking, we start with detection to locate the breach before proposing any repair.

Residential work across Redwood City covers the familiar range: foundations, basements, balconies, planters, and garage floors. The neighbourhoods closer to the bay see more groundwater pressure, and the systems we specify there reflect it.
