Leveled Patio in Broad Run, VA

In Broad Run, VA, a homeowner was faced with the frustrating challenge of an uneven patio, a common issue that not only disrupts the functionality of outdoor spaces but also poses risks of discomfort, safety concerns, and potential long-term damage to the property. The unlevel surface, as clearly shown in the before photo, had become a significant problem, making the patio less enjoyable and creating an eyesore in an otherwise beautiful outdoor area. Recognizing the need for a reliable and lasting solution, the homeowner turned to our experienced team at NV Waterproofing & Foundation Repair. We stepped in with our expertise and utilized the innovative PolyLevel system to address the issue. This advanced technique allowed us to stabilize and lift the sunken concrete slabs with precision, using high-strength polyurethane foam to restore the patio’s balance and structural integrity. But we didn’t stop there. To ensure the problem wouldn’t resurface, we applied the NexusPro Joint Sealant, a durable and water-resistant solution designed to prevent water from seeping into the joints and impacting the soil beneath the patio. This extra step not only protects the foundation but also extends the lifespan of the repair.   The results speak for themselves. As shown in the after photo, the transformation is nothing short of remarkable. The once uneven and problematic patio is now level, secure, and ready to be enjoyed for years to come. Thanks to our proven methods and attention to detail, the homeowner can now take pride in their outdoor space, knowing it’s both functional and protected against future issues.

Basement Waterproofing Success in Catlett, VA: From Wet to Worry-Free

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.
