Waterproofing Costs vs. Repeat Water Damage in Myrtle Beach, SC
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.

Sump Pump Installation and Repair in Myrtle Beach, SC
Sump pumps are a key 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.
Crawl Space Vapor Barriers in Myrtle Beach
Many homes in Myrtle Beach 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 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.
Commercial Wall Waterproofing in Myrtle Beach
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 found.
Shower Wall Waterproofing in Myrtle Beach
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.
Basement Wall Sealing in Myrtle Beach, SC
Basement wall sealing is a critical part of walls waterproofing. Long, hot and humid summers are the main stress on South Carolina plumbing, driving condensation on cold lines and heavy use of air conditioning drains. 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, healthier environment in your Myrtle Beach, SC basement.
Exterior Foundation Waterproofing in Myrtle Beach
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. Clay that swells when wet and shrinks in dry spells can shift buried sewer lines over time, leading to sags, separated joints and root intrusion. Proper drainage solutions, such as French drains, are also added to divert water away.

Foundation Crack Repair & Sealing in Myrtle Beach
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.

Frequently Asked Questions About Walls Waterproofing in Myrtle Beach
Shower wall waterproofing with a membrane system typically 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.
While minor DIY fixes like patching small cracks are possible, complete 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 ineffective results, wasted money, and worse water damage over time.
When professionally installed using high-quality materials, walls waterproofing can last for many decades, often 20 to 50 years or even longer. The lifespan depends on the materials used, the quality of installation, and environmental factors like soil movement and water exposure. Modern membranes and sealants are designed for lasting durability.
A shower wall waterproofing project typically 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, KBN Plumbing stands behind the quality of our walls waterproofing services. We offer full warranties on our materials and workmanship, giving you peace of mind. Warranty details will be provided with your project proposal, spelling out the coverage and duration of your waterproofing system.
Look for bubbling paint, soft drywall, stained baseboards and musty odors. White crust on block or stucco walls is another sign of moisture moving through. Loose tiles or cracked grout in a shower also suggest water is getting behind.
Shower remodels that change plumbing or drain locations often require a permit. Simple membrane replacement may not. We check local requirements and pull permits when needed.
Damp proofing is a less durable 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 the right choice.
