Serving Northern Virginia, D.C., and Suburban Maryland
Before & After
In Upper Marlboro, MD, one homeowner found themselves facing a familiar but frustrating issue—a sinking front entryway sidewalk. What once offered a welcoming path had become uneven and unsafe, casting doubt on both the home’s appearance and its structural integrity.
That’s where NV Waterproofing and Foundation Repair stepped in with innovative, lasting solutions. Our team used PolyLevel®, a high-density polyurethane foam, to gently lift and level the sunken concrete—restoring the walkway without the need for messy demolition or costly replacement. To protect that repair for the long haul, we applied NexusPro®, a UV-resistant joint sealant designed to keep water out and prevent soil erosion.
Now, the front entryway isn’t just level—it’s resilient, attractive, and built to withstand Maryland’s changing weather.
At NV Waterproofing and Foundation Repair, we don’t just fix concrete—we deliver confidence, curb appeal, and safe footing for years to come. If your sidewalk is sinking or cracked, let us help you reclaim the path forward with precision and care.
