Shower Wall Waterproofing in Minot AFB
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.

Crawl Space Encapsulation in Minot AFB
Crawl space encapsulation involves sealing the crawl space entirely with heavy-duty vapor barriers and often includes a dehumidifier. This not only waterproofs the walls but also controls humidity, preventing mold growth and wood rot in the crawl space. Big swings between summer heat and winter cold make pipes shift, which slowly loosens fittings over the years. An encapsulated crawl space can significantly improve indoor air quality and energy efficiency by keeping moisture from moving up into the home. We use durable, reinforced poly sheeting for walls and floors, sealed at all seams and penetrations.
Shower Pan Leak Repair and Waterproofing in Minot AFB, ND
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.
Commercial Wall Waterproofing in Minot AFB
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 reduce downtime. We also repair the plumbing behind those walls when leaks are discovered.
Exterior Foundation Waterproofing in Minot AFB
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. Heavy, expansive clay soils are common in North Dakota, and they swell and shrink with moisture and frost, stressing foundations and buried pipe. Proper drainage solutions, such as French drains, are also integrated to divert water away.
Crawl Space Vapor Barriers in Minot AFB
Many homes in Minot AFB have crawl spaces, which are very prone to moisture issues. Installing a heavy-duty vapor barrier on crawl space walls and floors is a key waterproofing strategy. This thick polyethylene sheeting prevents ground moisture from evaporating into the crawl space, protecting subflooring and joists and improving indoor air quality. It's an effective way to control humidity and prevent wood rot.
Waterproofing for Older Homes in Minot AFB, ND
Older homes, especially those built before modern waterproofing standards, are especially prone to water intrusion. Older homes may still have galvanized supply lines or cast iron drains, which can rust and restrict flow with age. 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.

Plumbing Leak Behind Walls in Minot AFB
A slow drip from a shower valve, supply stub or drain fitting can soak a wall for months before you notice. We find the leak with moisture meters, thermal imaging and pressure tests. The damaged section of pipe or valve is replaced, and wet drywall is cut out and dried. Once the cavity is dry, we restore the wall and seal any wet-area surfaces.

Frequently Asked Questions About Walls Waterproofing in Minot AFB
Shower wall waterproofing with a membrane system usually runs $1,200 to $3,500 including demolition and backer board, not counting new tile. Exterior block wall sealing often costs $800 to $3,000 depending on size. Below-grade foundation waterproofing generally ranges from $2,500 to $8,000.
Walls waterproofing is generally not recommended as a DIY project due to its complexity and the high importance of a sound foundation. It often involves heavy excavation, specialized equipment, precise material application, and knowledge of drainage principles and local building codes. Improper waterproofing can lead to more severe and costly damage down the line, so professional help is the smart choice.
For extensive walls waterproofing projects that involve excavation, significant structural changes, or changes to drainage systems, a permit from the Minot AFB building department may be required. We will advise you on any necessary permits and help with the application process so all work complies with local codes.
Walls waterproofing is a primary step in preventing future mold growth by eliminating the moisture source. However, it does not remove existing mold. If mold is already present, it will need to be professionally remediated before or along with the waterproofing process. Once the area is dry and mold-free, waterproofing will help keep it that way.
Waterproofing prevents the moisture mold needs to grow. Existing mold should be removed and the area dried before sealing. We remove affected materials when needed and recommend remediation for heavier growth.
Look for signs such as damp or wet spots on basement or crawl space walls, a musty odor, visible mold or mildew growth, efflorescence, a white powdery residue, on concrete or brick, and standing water. Cracks in foundation walls or bowing walls also indicate potential water entry issues. If you notice any of these, it's wise to get a professional inspection.
Damp proofing is a less robust solution, typically a spray-on asphalt coating that resists soil moisture but isn't designed to withstand hydrostatic pressure. Waterproofing uses stronger membranes, coatings, or drainage systems built to prevent liquid water from entering, even under pressure. For basements or crawl spaces in areas with high water tables or heavy rainfall, waterproofing is essential.
While minor DIY fixes like patching small cracks are possible, full walls waterproofing is best left to professionals. It involves specialized knowledge of drainage, foundation mechanics, and proper material application. Improper DIY work can lead to poor results, wasted money, and worse water damage over time.
