NV Waterproofing & Foundation Repair Before & After Photos

A backyard pool should be a place for summer fun and relaxation, but for one homeowner in Manassas, VA, the enjoyment was overshadowed by safety concerns when their concrete pool deck began to sink and settle, creating uneven surfaces and significant tripping hazards. In the "before" state, sections of concrete had settled at different rates, resulting in raised edges and uneven joints that posed a threat to barefoot guests, intensified by the risk of falls and injuries. The homeowner recognized additional problems like water pooling in sunken areas, which not only created slippery spots but also sped up the deterioration of both the concrete and the supporting soil, as well as the erosion caused by water seeping through open joints and cracks. These issues compromised the foundation and threatened to drive down property value—a serious concern for future resale. Wanting more than a cosmetic fix, the homeowner turned to our team for a solution that was effective, durable, and minimally disruptive compared to total replacement. Our assessment led us to recommend the PolyLevel® system, a high-strength, lightweight polyurethane foam that is injected through small holes in the affected slabs. As the foam expands, it fills voids beneath the slabs, gently lifting them back to their proper position, all while being waterproof and quick to cure, allowing for immediate use. This process restored a smooth, level surface to the pool deck and eliminated the dangerous ledges. To protect the repair and prevent further damage, we applied NexusPro® Joint Sealant to all joints and cracks. This silicone-based, flexible sealant withstands harsh weather, UV, and seasonal expansion, creating a watertight barrier that keeps moisture from eroding the soil beneath the slabs. The “after” effect was a safe, visually appealing pool deck, free of tripping hazards, with sealed joints protecting the foundation and restoring the homeowner’s peace of mind. By choosing these advanced concrete solutions, the homeowner avoided the expense and upheaval of deck replacement and regained a beautiful, secure backyard oasis that will last for years to come.

In Reston, VA, a local homeowner was dealing with a driveway riddled with cracks and uneven concrete slabs. These issues not only created an unsightly first impression but also presented a serious tripping hazard and risk of further structural damage. Uneven concrete is often the result of shifting soils and erosion beneath the surface—problems that can worsen over time if left untreated.

To address these concerns, our team utilized the innovative PolyLevel system, a high-performance polyurethane foam that is injected beneath the slabs to gently lift and level the concrete without the mess or cost of full replacement. Once the surface was restored to its proper elevation, we applied NexusPro Joint Sealant to seal all cracks and joints. This premium sealant is designed to withstand extreme weather conditions and helps prevent future water infiltration and soil erosion.

Now, as clearly seen in the after photo, the driveway is level, clean, and visually appealing. The transformation not only enhances curb appeal but also ensures long-term durability and safety.

For homeowners in Quantico, VA, persistent water seepage in the basement is more than an inconvenience; it’s a serious issue that can lead to moisture damage, mold growth, and structural problems. One such homeowner faced these challenges in their older property, which had suffered from water intrusion for years. Determined to resolve the issue, they turned to NV Waterproofing & Foundation Repair for an effective, long-lasting solution.

Our experts began by addressing cracks in the foundation that allowed water to seep into the basement. By injecting these cracks with advanced sealant materials, we stopped water intrusions at the source, ensuring the home’s structural integrity and reducing future risks. Foundation crack injection is a critical step in any waterproofing effort, as it targets vulnerabilities that can worsen over time.

To provide comprehensive protection, we installed a waterproofing system on both the exterior and interior of the property. On the exterior, we applied a robust waterproof membrane to create a barrier against water trying to infiltrate the foundation. On the interior, we installed the WaterGuard drainage system beneath the basement floor’s perimeter. This innovative solution effectively captures any water that manages to enter and channels it away to a sump pump. With the addition of the CleanSpace encapsulation system, we provided an extra layer of defense, shielding the space from direct moisture contact and eliminating the damp conditions that encourage mold growth.

The basement transformation was dramatic. What was once a water-damaged, unusable area now stands as a dry, protected, and functional space. The exterior and interior waterproofing measures, combined with foundation crack injection, offer lasting peace of mind to the homeowner. They no longer worry about water intrusion or the damaging effects of mold, and the improved structural stability has increased the value and safety of their property.
