Exterior Foundation Waterproofing in Fargo
Exterior foundation waterproofing involves excavating around the foundation to apply a waterproof membrane or coating directly to the wall. This is often the most reliable 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. Frost heave can shift soil around sewer lines and misalign joints, which often shows up as slow drains or backups. Proper drainage solutions, such as French drains, are also added to divert water away.

Drainage System Integration in Fargo, ND
Lasting walls waterproofing often requires a solid 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 Fargo, ND properties, so water is efficiently managed and moved away from your home's vulnerable areas.
Interior Walls Waterproofing in Fargo, ND
Interior walls waterproofing focuses on managing water that has already passed through the foundation walls. This usually 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 effectively stops it from pooling inside your living space. This solution is less disruptive than exterior excavation and works well where exterior access is limited.
Shower Pan Leak Repair and Waterproofing in Fargo, ND
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 confirm 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 proves the pan is watertight before tile.
Commercial Wall Waterproofing in Fargo
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.
Foundation Crack Repair & Sealing in Fargo
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 indicate structural issues that need a thorough assessment before sealing. Addressing these early prevents further water damage and costly future repairs.

Frequently Asked Questions About Walls Waterproofing in Fargo
The cost of walls waterproofing in Fargo, ND can vary a great deal based on the method used, the extent of the damage, and the size of your foundation. Basic crack sealing might range from $300 to $800 per crack, while a full exterior foundation waterproofing project could be $8,000 to $20,000 or more.

Absolutely. By preventing water intrusion through your walls, waterproofing significantly 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.
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 in force.
Interior waterproofing addresses water after it has entered the foundation, typically managing it with sealants and drainage systems inside the basement or crawl space. Exterior waterproofing prevents water from reaching the foundation walls in the first place, usually by excavating and applying membranes or coatings to the outside of the foundation.
Yes, HPN 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, outlining the coverage and duration of your waterproofing system.
Waterproofing prevents the moisture mold needs to grow. Existing mold should be removed and the area dried before sealing. We remove affected materials when needed and recommend remediation for larger growth.
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 warning signs, as they often point to ongoing water intrusion.
For extensive walls waterproofing projects that involve excavation, major structural changes, or changes to drainage systems, a permit from the Fargo 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.
