Cracks and voids plagued this Brandywine, MD, homeowner's basement entryway. This could lead to water invasion and soil movement, endangering the property's foundation. As you see in the before photo, the concrete was no longer stable. Our expert team employed the PolyLevel® system, injecting high-strength polyurethane foam to stabilize and lift the slabs. Coupled with NexusPro® Joint Sealant, these solutions effectively sealed the cracks, preventing future soil erosion. Notice in the after photo, the entryway is once again level and secure, demonstrating our commitment to quality concrete repair.
A homeowner in Bowie, MD, was repeatedly dealing with water entering their basement during heavy rains. This ongoing problem created a damp, unusable space and raised concerns about potential mold growth and long-term structural damage. Tired of temporary fixes, they sought a reliable, permanent solution for basement waterproofing in Bowie MD to protect their home and investment.
Following a thorough home inspection, our System Design Specialist identified the key points of water intrusion and recommended a comprehensive interior waterproofing system. Our production team began by installing the WaterGuard® drainage system beneath the basement floor. This innovative system intercepts water at the wall-floor joint and channels it away, preventing it from ever reaching the basement floor.
The collected water is then directed to our TripleSafe™ Sump Pump System. This powerful unit provides three levels of protection, including a battery backup pump, ensuring the basement stays dry even during a power outage. To complete the system, we installed an IceGuard® discharge line to prevent freezing and blockages during cold weather. The result was a completely dry, secure basement, giving the homeowner lasting peace of mind and reclaiming their valuable lower-level living space.

A homeowner in Upper Marlboro, MD, was dealing with a frustrating issue—water pooling in the corners of their concrete driveway near the garage door. Over time, the driveway had settled unevenly, causing the corners to sink and creating low spots where water would collect after every rain. Not only was this an inconvenience, but the standing water also posed a risk of long-term damage to the concrete and the garage foundation.
To resolve the issue, NV Waterproofing and Foundation Repair provided expert concrete leveling services. Using our advanced PolyLevel system, we lifted and stabilized the sunken corners of the driveway with precision. This process restored the driveway to its proper slope, allowing water to drain away from the garage door instead of pooling. The PolyLevel system is not only quick and effective but also provides a long-lasting solution that prevents further settling.
The homeowner was thrilled with the results. Their driveway is now level, functional, and free of water pooling issues, protecting both the concrete and the garage from future damage.
