Shower Wall Waterproofing in Florence
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.

Basement Wall Sealing in Florence, SC
Basement wall sealing is a critical part of walls waterproofing. Warm weather for most of the year means water heaters, irrigation lines and outdoor fixtures in South Carolina see year-round use with little seasonal rest. 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 Florence, SC basement.
Shower Pan Leak Repair and Waterproofing in Florence, SC
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 confirms the pan is watertight before tile.
Plumbing Leak Behind Walls in Florence
A slow drip from a shower valve, supply stub or drain fitting can soak a wall for months before you notice. We locate 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.
Below-Grade and Basement Wall Waterproofing in Florence
Homes built in the 1980s and early 1990s may still have gray polybutylene supply lines, which are known to fail and are worth replacing. 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.
Drainage System Integration in Florence, SC
Lasting walls waterproofing often requires a robust 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 Florence, SC properties, so water is efficiently managed and moved away from your home's vulnerable areas.
Crawl Space Vapor Barriers in Florence
Many homes in Florence 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 effective way to control humidity and prevent wood rot.

Laundry Room and Utility Wall Waterproofing in Florence, SC
Washing machine hoses, utility sinks and water heaters can all leak into nearby walls. We replace burst-prone rubber hoses with braided stainless hoses and install leak pans and shutoff valves. Walls around water heaters and laundry boxes can be sealed to resist water damage. These small upgrades prevent costly drywall repairs.

Frequently Asked Questions About Walls Waterproofing in Florence
The cost of walls waterproofing in Florence, SC can vary a lot, typically ranging from $3,000 for interior crack sealing to $15,000 or more for extensive exterior foundation waterproofing with drainage systems. Factors like the size of the area, severity of water damage, chosen methods, and accessibility all affect the final price. We provide detailed, upfront quotes after a thorough inspection.
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.
When professionally installed using high-quality materials, walls waterproofing can last for 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 long-term durability.
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.
Yes. Sealing a wall with an active leak behind it traps water and causes more damage. We always fix the leak and dry the cavity first.
We commonly install Schluter Kerdi, Custom RedGard, Laticrete Hydro Ban and similar systems. The right choice depends on your shower design and tile. We follow each manufacturer's installation steps to keep the warranty valid.
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 a few days.
KBN Plumbing works with reputable manufacturers known for high-quality waterproofing products. We commonly use products from brands like Xypex, Tremco, and Sika for their proven effectiveness and durability, from crystalline admixtures to elastomeric membranes and sealants. We select the best product for your foundation type and site.
