Shower Wall Waterproofing in Grants Pass
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 reinforcement before new tile is set.

Drainage System Integration in Grants Pass, OR
Effective walls waterproofing often requires a solid drainage system to divert water away from your foundation. This can include interior perimeter drains that channel water to a sump pump, or exterior French drains that collect surface water. Our team designs and installs custom drainage solutions for Grants Pass, OR properties, so water is managed well and moved away from your home's vulnerable areas.
Commercial Wall Waterproofing in Grants Pass
Restaurants, gyms, salons and offices often have restrooms, locker rooms and kitchens with constant water exposure. We waterproof commercial showers, mop sink walls and restroom wet walls with durable membranes. Work can be scheduled after hours to limit downtime. We also repair the plumbing behind those walls when leaks are discovered.
Foundation Crack Repair in Grants Pass
Even small cracks in your foundation walls can allow water to seep into your basement or crawl space. Our walls waterproofing service includes foundation crack repair using specialized epoxy or polyurethane injection techniques. These materials fill and seal cracks, preventing future water entry and often strengthening the foundation. Addressing cracks early in Grants Pass homes is important to avoid larger, more costly structural issues.
Below-Grade and Basement Wall Waterproofing in Grants Pass
Oregon has a mix of older homes with galvanized supply pipe and cast iron drains alongside newer homes plumbed with PEX. Wherever a home has a basement or below-grade walls, heavy rain and snowmelt can push water through foundation walls and cracks. We seal cracks with injection products, apply interior or exterior waterproofing and install drainage where needed. A sump pump may be added if groundwater builds up.
Waterproofing for Older Homes in Grants Pass, OR
Older homes, especially those built before modern waterproofing standards, are particularly prone to water intrusion. Oregon has a mix of older homes with galvanized supply pipe and cast iron drains alongside newer homes plumbed with PEX. 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 take care to respect the existing structure while installing modern, effective waterproofing, with attention to the challenges of older brick and stone foundations.
Waterproofing Costs vs. Repeat Water Damage in Grants Pass, OR
Waterproofing a shower or wall costs much less than repeated drywall, cabinet and flooring repairs. Ignoring moisture also invites mold, which can be expensive to remediate. A typical shower wall waterproofing project falls in the low thousands, while exterior block sealing varies with wall size. We give you a written quote so you can compare options clearly.

Foundation Crack Repair & Sealing in Grants Pass
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 for good. 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 signal structural issues that need a thorough assessment before sealing. Addressing these early prevents further water damage and expensive future repairs.
