Four Decades of Waterproofing Across Los Angeles County
Waterproofing isn’t one service among many for WICR — it’s the entire business, and has been since the company was founded in 1985. That’s why LA-area HOAs, property managers, and builders bring us the work that has to hold up: new-construction decks that need to be right from day one, and aging structures where the original waterproofing has quietly failed.
We work the full LA metro, including the San Gabriel Valley, the condominium- and townhome-dense communities of the eastern county, the Westside and West Hollywood, the South Bay, and the Santa Clarita Valley.

Why LA-Area Structures Need a Waterproofing Specialist
The Los Angeles region packs an enormous inventory of condominiums, townhomes, and multi-family buildings — many built in the deck-and-balcony boom decades ago and now well past the service life of their original waterproofing. Elevated wood balconies and shared deck structures across the county are exactly the assemblies that fail from water intrusion once the membrane ages out.
LA’s pattern of long dry stretches followed by concentrated winter rain is deceptively hard on decks: coatings dry out and crack in the heat, then the first heavy rains drive water straight into the openings. Four decades of LA-area work means we know how these systems fail here — and how to build them so they last.
Basement & Below-Grade Waterproofing in Los Angeles
Subterranean parking is everywhere in Los Angeles, and so is below-grade water intrusion. Floor-to-wall cold joints, pour strips, and retaining walls under hydrostatic pressure leak in ways that surface patching will not solve.
WICR performs blind-side and curtain injection with hydrophobic polyurethane resin, negative-side coatings, and full podium and planter membrane systems. At a West Los Angeles condominium community, we treated approximately 920 linear feet of leaking floor-to-wall cold joints and 2,957 square feet of below-grade retaining walls across a two-level subterranean garage — without excavation.
What Working With WICR Actually Looks Like
The waterproofing itself is rarely what worries a board. The worry is six weeks of resident complaints, what turns up once the deck is opened, and the change order that follows.
We assess before we bid. On a 365-deck community we evaluate deck by deck rather than pricing off a sample. Serviceable decks get an overlay; only what needs rebuilding gets rebuilt. Your bid reflects the actual condition of the property.
We phase around residents. For most units an elevated deck or walkway is the only way in. Work is sequenced to maintain access and finish building by building.
We tell you what we find. When we open an assembly and find damage the assessment couldn’t see, you get photographs and a written explanation before anything changes.
We document for your reserve study. A record of what was installed and where it sits in its service life — for your reserve analyst now, and for the board that replaces you.
