Walls Waterproofing in Kennewick, WA

Professional Walls Waterproofing Services in Kennewick, WA

Shower Wall Waterproofing in Kennewick

Tile and grout are not waterproof on their own, so water reaches the backer board in every shower. If the walls were built without a proper membrane, moisture soaks into studs and drywall. We remove failing tile, install cement board or foam board and apply a membrane such as Schluter Kerdi, RedGard or Hydro Ban. Seams, corners and niches get extra attention before new tile is set.

Exterior Foundation Waterproofing in Kennewick

Exterior foundation waterproofing involves excavating around the foundation to apply a waterproof membrane or coating directly to the wall. This is often the most reliable method for preventing water from entering the basement or crawl space. We use high-quality asphalt-modified polyurethane membranes or polymer-based coatings that resist hydrostatic pressure and soil movement. Crawlspaces and basements are both common in Washington homes, and a damp crawlspace is often the first sign of a drainage or plumbing problem. Proper drainage solutions, such as French drains, are also added to divert water away.

Waterproofing for Older Homes in Kennewick, WA

Older homes, especially those built before modern waterproofing standards, are particularly prone to water intrusion. Mid-century homes often have galvanized supply lines and cast iron drains, while some 1980s and 1990s homes were plumbed with gray polybutylene. Many older foundations may lack adequate exterior drainage or proper sealing. We specialize in assessing and upgrading waterproofing systems for these properties, often combining exterior excavation with interior drainage solutions. We respect the existing structure while installing modern, effective waterproofing, with attention to the challenges of older brick and stone foundations.

Exterior Block Wall Waterproofing in Kennewick, WA

Block and stem walls often show efflorescence, which is the white mineral crust left when water passes through masonry. Irrigation and sprinklers aimed at the house are common culprits. We adjust or reroute irrigation, clean the wall and apply a breathable masonry sealer or elastomeric coating. Proper grading and drip line placement help keep the wall dry for good.

Crawl Space Vapor Barriers in Kennewick

Many homes in Kennewick have crawl spaces, which are highly susceptible to moisture issues. Installing a heavy-duty vapor barrier on crawl space walls and floors is a key waterproofing strategy. This thick polyethylene sheeting stops ground moisture from evaporating into the crawl space, protecting subflooring and joists and improving indoor air quality. It's an affordable way to control humidity and prevent wood rot.

Foundation Crack Repair & Sealing in Kennewick

Even minor cracks in foundation walls can allow serious water intrusion. Our services include crack repair using epoxy or polyurethane injection to seal these entry points permanently. This method fills the entire depth of the crack, restoring strength and preventing water penetration. We address both vertical and horizontal cracks, knowing that horizontal cracks can indicate structural issues that need a thorough assessment before sealing. Addressing these early prevents further water damage and expensive future repairs.

Basement Wall Sealing in Kennewick, WA

Basement wall sealing is a key part of walls waterproofing. Washington has two very different climates, with long, wet and mild seasons in the west and hot, dry summers and cold winters in the east. We apply high-quality sealants to porous concrete and masonry walls to prevent moisture from wicking through and causing dampness, mold, or musty odors. This service can be performed alone or as part of a larger waterproofing system, offering a drier and healthier environment in your Kennewick, WA basement.

Shower Pan Leak Repair and Waterproofing in Kennewick, WA

A cracked or poorly sloped shower pan often causes wet baseboards and stained ceilings below. We test the pan by plugging the drain and flooding it to verify the leak. Then we rebuild the pan with correct pre-slope, a new liner or bonded membrane and a properly clamped drain. A second flood test proves the pan is watertight before tile.
