Below-Grade and Basement Wall Waterproofing in Atlantic City
New Jersey has a lot of older housing, and many prewar homes still carry galvanized supply pipe and cast iron drains that are nearing the end of their life. 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.

Plumbing Leak Behind Walls in Atlantic City
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.
Exterior Block Wall Waterproofing in Atlantic City, NJ
Block and stem walls often show efflorescence, which is the white mineral crust left when water passes through masonry. Irrigation and sprinklers aimed at the house are common culprits. We adjust or reroute irrigation, clean the wall and apply a breathable masonry sealer or elastomeric coating. Proper grading and drip line placement help keep the wall dry for good.
Cost-Effective Waterproofing Solutions in Atlantic City, NJ
We believe in providing transparent and cost-effective walls waterproofing solutions without cutting corners on quality.

From detailed estimates to explaining the long-term savings of preventing water damage, we make sure you understand your investment.

Commercial Walls Waterproofing in Atlantic City
Beyond residential properties, GLN Plumbing also offers walls waterproofing services for commercial buildings in Atlantic City. Protecting commercial basements, equipment rooms, and underground parking garages from water damage is essential to business operations. We understand the need for minimal disruption and efficient project completion for commercial clients. Our team works with property managers and business owners to implement robust waterproofing solutions that fit the demands of commercial structures and their code requirements.
Shower Wall Waterproofing in Atlantic City
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.
Exterior Foundation Waterproofing in Atlantic City
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. Sandy soils near the shore drain quickly but shift easily, which can stress buried water lines and sewer laterals over the years. Proper drainage solutions, such as French drains, are also added to divert water away.

Foundation Crack Repair & Sealing in Atlantic City
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 permanently. 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.
