Concrete Repair Before & After Photos

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.

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.
