NV Waterproofing & Foundation Repair Before & After Photos

What was once a damp, cluttered space in an Arlington, VA basement has now been completely transformed into a dry, neat, and reliable part of the home. The homeowner had been dealing with persistent moisture issues, so they turned to NV Waterproofing and Foundation Repair for a long-term solution—one that didn’t just mask the symptoms but addressed the root of the problem.

We installed our WaterGuard® interior drainage system along the perimeter to effectively capture and redirect incoming water before it could reach the floor. To further protect the space, our team applied the CleanSpace® vapor barrier, sealing the walls against moisture and creating a brighter, cleaner environment. We also installed the powerful SuperSump® system to ensure consistent water removal, even during heavy storms.

But we didn’t stop there—we completed targeted exterior drainage improvements to reinforce protection and make certain water stays out for good.

Today, that Arlington basement isn’t just cleaner—it’s confidently protected. At NV Waterproofing and Foundation Repair, we believe peace of mind begins from the ground up.

A homeowner in Manassas, VA, quickly realized their dream backyard pool was at risk when the surrounding concrete pool deck began to show serious problems. Uneven and sunken slabs created tripping hazards and unsightly cracks, making both safety and aesthetics a challenge for anyone using the space. Additionally, water from rain and pool use was pooling in low spots, causing slippery surfaces and further soil erosion beneath the deck. These issues not only threatened the safety of family and guests but also compromised the value and enjoyment of the home.

Seeking an effective solution, the homeowner reached out to our team for a professional assessment. We identified the main cause of settlement: soil erosion under the slabs—a common issue in Manassas due to its clay-rich ground and fluctuating moisture. To address both the immediate hazards and prevent future damage, we recommended our two-part approach: the cutting-edge PolyLevel® concrete leveling system and NexusPro® Joint Sealant.

The repair process began with drilling small holes into the affected concrete slabs, allowing us to inject high-strength PolyLevel® polyurethane foam beneath the surface. As the foam expanded, it filled voids, stabilized the soil, and gently lifted the slabs back to their original positions. The process was quick, clean, and minimized disruption, giving the pool deck a level, safe surface once again. PolyLevel® foam is waterproof and lightweight, reducing the risk of future settling and ensuring long-term durability, even in a wet poolside environment.

To provide further protection, we sealed all cracks and joints with NexusPro® Joint Sealant. This flexible, weather-resistant sealant prevents water from seeping beneath the slabs, protecting the soil and concrete from additional erosion. The result was a clean, finished appearance that not only improved the look of the deck but also safeguarded it for years to come.

Thanks to modern concrete leveling technology, the homeowner’s pool deck was transformed from a liability into a safe and attractive outdoor gathering space. The project was completed in a single day, with minimal mess and immediate results, giving the homeowner peace of mind and renewed pride in their backyard. If you’re facing similar issues with your pool deck in Manassas, VA, the PolyLevel® system and NexusPro® Joint Sealant offer a fast, effective, and lasting

A homeowner in Aldie, VA was facing a sunken and uneven driveway that allowed water to pool, creating a risk for long-term damage and safety hazards. The issue was evident in the unlevel concrete, which is a common problem in Northern Virginia due to shifting soil and drainage concerns.

At NV Waterproofing and Foundation Repair, we addressed the issue using our trusted NexusPro Joint Sealant—a highly effective, waterproof solution that fills joints and helps prevent water from seeping beneath the surface. By sealing the gaps and improving water runoff, we help protect the driveway and surrounding foundation from future erosion.

In Catlett, VA, a homeowner was dealing with a persistent and potentially damaging issue—water intrusion in the basement. Every time it rained, water would seep into the space, creating damp conditions and raising serious concerns about mold growth, structural damage, and indoor air quality. The before photo clearly shows signs of moisture and the beginnings of what could become long-term basement problems if left untreated.

When the homeowner reached out to NV Waterproofing & Foundation Repair, our expert team promptly scheduled an inspection and developed a customized waterproofing plan to permanently resolve the issue. Our goal was to turn the damp, vulnerable basement into a dry, healthy, and usable part of the home.

To accomplish this, our crew installed a full interior waterproofing system starting with the WaterGuard® drainage system, which discreetly captures water seepage at the base of the walls and under the floor. From there, water is funneled directly into the SuperSump® system, a powerful and reliable sump pump designed to keep basements dry under even the harshest weather conditions. For added protection during winter months, we installed IceGuard®, a discharge line system that prevents water from backing up if the pipes freeze.

In addition, we applied the CleanSpace® vapor barrier along the interior basement walls. This heavy-duty liner acts as a moisture and mold barrier, dramatically improving the overall air quality while giving the basement a clean, finished appearance.

To further protect the entry point of the basement, where surface water was entering near the door, we installed a trench drain. This feature helps capture and redirect rainwater before it has a chance to enter the basement—an essential defense in properties with exterior basement doors or sloped landscapes.

As shown in the after photo, the transformation is striking. The basement is now completely dry, well-protected, and safe for storage or future finishing. Thanks to NV Waterproofing’s professional team and proven waterproofing systems, this Catlett, VA homeowner can enjoy peace of mind knowing their basement is secure for years to come.
