Shower Wall Waterproofing in Prairieville
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.

Sump Pump Installation and Repair in Prairieville, LA
Sump pumps are a critical part of many interior waterproofing systems, particularly in homes that see heavy rainfall. We install high-capacity sump pumps designed to handle large volumes of water, keeping your basement dry even during flash floods. Our services include primary sump pump installation, battery backup sump pump systems for power outages, and routine maintenance or repair of existing units. We make sure the discharge line is routed correctly so water does not circulate back toward the foundation.
Below-Grade and Basement Wall Waterproofing in Prairieville
Homes from the late seventies through the mid nineties may contain gray polybutylene supply pipe, which is prone to failure. 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 collects.
Waterproofing Costs vs. Repeat Water Damage in Prairieville, LA
Waterproofing a shower or wall costs far 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.
Plumbing Leak Behind Walls in Prairieville
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 walls.
Commercial Wall Waterproofing in Prairieville
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 found.
Interior Walls Waterproofing in Prairieville, LA
Interior walls waterproofing focuses on managing water that has already penetrated the foundation walls. This typically involves installing an interior drainage system, often called a French drain, along the perimeter of the basement floor. Water is collected and channeled to a sump pump, which then sends it safely away from the foundation. While not preventing water from entering the wall, it stops it from pooling inside your living space. This solution is less disruptive than exterior excavation and is suitable where exterior access is limited.

Exterior Foundation Waterproofing in Prairieville
Exterior foundation waterproofing involves excavating around the foundation to apply a waterproof membrane or coating directly to the wall. This is often the most effective 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. Much of Louisiana sits on soft, expansive clay that swells and shrinks with moisture, which can shift slabs and crack buried pipes. Proper drainage solutions, such as French drains, are also integrated to divert water away.

Frequently Asked Questions About Walls Waterproofing in Prairieville
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 usually ranges from $2,500 to $8,000.
Sprinklers and drip lines aimed at the house are the most common cause. Heavy storms and poor grading also send water toward walls. Masonry absorbs that water and leaves mineral deposits as it dries out.
The duration of a walls waterproofing project varies depending on its scope. Minor crack repairs might take a few hours, while an interior drainage system could take 1 to 3 days. A full exterior foundation waterproofing project, involving excavation around the entire home, could take 3 to 7 days or more. We provide a clear timeline during our initial consultation.
Key signs you need walls waterproofing include damp or wet basement walls, visible mold or mildew growth, a musty odor in your basement or crawl space, efflorescence on concrete walls, cracks in the foundation, or standing water after heavy rains. Don't ignore these indicators, as they often point to ongoing water intrusion.
A shower wall waterproofing project usually takes two to four days, including drying time between coats. Exterior block sealing can often be completed in a day. Larger foundation jobs may take several days.
Yes. Sealing a wall with an active leak behind it traps water and causes more damage. We always repair the leak and dry the cavity first.
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.
Absolutely. By preventing water intrusion through your walls, waterproofing greatly reduces the moisture and humidity levels in your basement or crawl space. This creates an environment less friendly to mold and mildew growth, improving air quality and protecting your belongings from moisture damage.
