NV Waterproofing & Foundation Repair serving Quantico, VA

A homeowner in Quantico, VA contacted NV Waterproofing & Foundation Repair after noticing sitting water in the crawl space, musty smells coming from under the home, and sagging, bouncy floors inside the rambler-style house. These symptoms can be signs of a damp crawl space, poor moisture control, wood rot, and weakened floor support.

To find the source of the problem, one of our Design Specialists completed a full crawl space inspection. During the inspection, our Design Specialist found standing water in the crawl space and discovered that the floor joists and beams were beginning to rot. As the wood weakened, the floors above started to slope, sag, and feel bouncy when walked on.

To protect the home from future crawl space moisture problems, our team installed a complete crawl space encapsulation system. This included CleanSpace vapor barrier to help seal the crawl space, drainage matting to direct water, a crawl space sump pump to remove water, and SilverGlo insulation to improve energy efficiency and protect the space from outside temperatures. We also installed a SaniDry dehumidifier to help control humidity and improve the air conditions inside the home.

To address the sagging floors, our crew added new steel beams and SmartJacks to provide additional floor support. This system helped lift and stabilize the floors above while giving the crawl space the structural support it needed.

With the crawl space sealing, moisture control, sump pump system, and floor support installed, the homeowner was happy with the outcome of the project. The home now has better protection against standing water, musty smells, wood rot, poor air quality, and sagging floors.

A homeowner in Quantico, VA began noticing sections of her concrete sidewalk were sinking and becoming uneven, creating cracks and raised edges along the path leading to her front door. What started as minor settlement had developed into a noticeable tripping hazard, especially concerning with neighbors and guests frequently walking up to the home. The uneven concrete not only posed a safety risk but also hurt the overall appearance of the property. Wanting a professional sidewalk repair solution without tearing out and replacing the slabs, she contacted NV Waterproofing and Foundation Repair for a free estimate on concrete repair and concrete leveling in Quantico, Virginia.

After a detailed inspection, our team determined that soil erosion beneath the sidewalk was causing the concrete to settle and shift. We recommended lifting and stabilizing the slabs using PolyLevel® polyurethane foam — an advanced concrete leveling system designed to precisely raise sunken concrete. Once the sidewalk was restored to its proper height, we sealed the joints and cracks with NexusPro® joint sealant to help prevent water intrusion and future settlement. The completed sidewalk repair eliminated tripping hazards, improved curb appeal, and provided long-lasting protection, restoring both safety and peace of mind for the homeowner.

In Quantico, VA, a homeowner was dealing with a patio that had seen better days. Cracks had spread across the surface, and the entire slab was leaning toward the house, creating a recipe for trouble. Not only was it an eyesore, but the slope also posed a real risk of water pooling near the foundation, which could lead to costly damage down the road.

Our team at NV Waterproofing and Foundation Repair got to work with a plan to fix the problem for good. First, we used our PolyLevel system to lift and level the patio, eliminating the dangerous slope and restoring its stability. Then, we sealed the cracks with NexusPro Joint Sealant, ensuring water couldn’t seep in and cause further damage.

The result? A patio that’s level, sturdy, and ready for use again—plus, the homeowner can rest easy knowing their foundation is protected from water intrusion. If your patio is cracked, sloping, or causing headaches, NV Waterproofing and Foundation Repair has the tools and expertise to make it right.

With our reputation for delivering solutions backed by a remarkable customer experience, we were ready to tackle this challenge head-on. Upon receiving the call, our Customer Care team quickly scheduled a house visit. Our System Design Specialist conducted a thorough examination of the basement. Realizing the urgency and intensity of the water intrusion, they recommended a comprehensive solution; installing WaterGuard along the basement's perimeter, a TripleSafe sump pump to efficiently remove collected water, CleanSpace liner to encapsulate the area and ensure its dryness, and an IceGuard to prevent freezing and blockages in colder months. Our dedicated production team, led by a skilled foreman and supported by proficient installers, swung into action, meticulously installing each component. The WaterGuard system was strategically integrated into the basement's layout to capture water at its entry point. Next, the TripleSafe sump pump—a standout for its reliability and performance—was set up, promising round-the-clock protection against basement flooding. The CleanSpace liner provided an additional protective layer, isolating the living space from moisture and pests.

When a homeowner in Quantico, VA, noticed their front porch was sinking and pulling away from the house, they knew immediate action was needed. The unstable porch not only posed a safety hazard but also risked further damage to the home's structure. After inspecting the problem, we identified that weak, shifting soil had caused uneven settling, leaving the porch in urgent need of support.

Our team quickly got to work. First, we carefully excavated beneath the porch, ensuring access to the unstable areas creating the problem. Then, we installed Smart Jacks—an adjustable, high-strength support system specifically designed to stabilize and lift sunken structures. Using precision tools, we incrementally lifted the porch back to its original position, restoring both its functionality and appearance.

The results were outstanding. The once-sinking porch was now solid and level, offering the homeowner peace of mind and a welcoming entrance once again. Thanks to the Smart Jacks installation, the porch was protected from future settling, ensuring long-lasting stability and safety.
