Exterior Foundation Waterproofing in Jersey 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 strain buried water lines and sewer laterals over the years. Proper drainage solutions, such as French drains, are also integrated to divert water away.

We believe in providing transparent and cost-effective walls waterproofing solutions without cutting corners on quality.

We use durable materials and proven techniques to provide lasting protection, reducing the chance of future repairs. Our goal is to deliver value and peace of mind.
Foundation Crack Repair in Jersey City
Even small cracks in your foundation walls can allow water to seep into your basement or crawl space. Our walls waterproofing service includes foundation crack repair using specialized epoxy or polyurethane injection techniques. These materials fill and seal cracks, preventing future water entry and often strengthening the foundation. Addressing cracks promptly in Jersey City homes is important to avoid larger, more costly structural issues.
Foundation Crack Repair & Sealing in Jersey 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 costly future repairs.
Commercial Wall Waterproofing in Jersey City
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.
Exterior Block Wall Waterproofing in Jersey 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 frequent 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.
Interior Walls Waterproofing in Jersey City, NJ
Interior walls waterproofing focuses on managing water that has already passed through 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.

Crawl Space Encapsulation in Jersey City
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. Hot, humid summers and cold winters put New Jersey plumbing through wide seasonal swings that stress joints, valves and water heaters alike. An encapsulated crawl space can noticeably 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.

Frequently Asked Questions About Walls Waterproofing in Jersey City
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 generally ranges from $2,500 to $8,000.
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.
Yes, GLN Plumbing stands behind the quality of our walls waterproofing services. We offer comprehensive warranties on our materials and workmanship, giving you peace of mind. Warranty details will be provided with your project proposal, outlining the coverage and duration of your waterproofing system.
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 essential.
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.
Yes. Our workmanship is warrantied, and many membrane systems carry their own manufacturer warranty when installed correctly. We explain the coverage in your written estimate.
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.
For extensive walls waterproofing projects that involve excavation, major structural changes, or changes to drainage systems, a permit from the Jersey City building department may be required. We will advise you on any required permits and help with the application process so all work complies with local codes.
