Before & After Photos

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.

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.

A homeowner in Culpeper, Virginia, contacted us with a pressing concern about their front sidewalk. The concrete slabs had sunk and become uneven, creating both an eyesore and a safety hazard. Understanding the need for a reliable and durable solution, the homeowner trusted our expertise in concrete repair to restore their walkway to its original condition.

After scheduling an inspection, our System Design Specialist conducted a comprehensive evaluation of the property. It was determined that the concrete slabs needed stabilization and lift to eliminate the hazard and restore the sidewalk's appearance. To achieve this, we recommended our proven concrete repair solutions, including the use of PolyLevel® and NexusPro®.

On the day of the repair, our skilled production team, led by an experienced foreman, arrived promptly to tackle the issue. We began by carefully drilling small, minimally invasive holes into the affected concrete sections. Using the PolyLevel® system, we injected high-strength polyurethane foam beneath the slabs. The foam expanded and lifted the sunken concrete back to its proper height, ensuring stability and leveling the sidewalk seamlessly.

To further protect the repaired surface, we applied NexusPro® Joint Sealant. This advanced sealant filled in cracks and joints, preventing water and moisture from seeping in and causing further damage. Designed for long-term durability, NexusPro® offers superior resistance to UV rays and harsh weather, making it ideal for Culpeper's climate conditions.

Once the repair was complete, our team cleaned the site thoroughly, leaving the walkway not only functional but attractive as well. The homeowner was thrilled with the results, enjoying a safer and more stable sidewalk that enhanced both the safety and curb appeal of their property.

Take a look at the before photo of this Aldie, VA home, and you’ll notice a common but serious issue—an uneven sidewalk and a leaning, broken patio step. These problems not only created an unsafe entrance but also detracted from the home’s curb appeal. Uneven concrete can be a hazard for trips and falls, especially in high-traffic areas like sidewalks and entryways.

To address this, our team implemented a straightforward yet highly effective solution: the PolyLevel system. This advanced technique allowed us to lift and stabilize the sunken concrete slabs, expertly realigning them to their original position. But we didn’t stop there. To ensure the repair would stand the test of time, we applied NexusPro Joint Sealant. This durable sealant filled in cracks and created a waterproof barrier, preventing water from seeping in and causing future shifting or damage.

The after photo tells the full story of the transformation. The sidewalk and patio step are now level, safe, and fully functional, restoring both safety and visual appeal to the home’s entrance. Thanks to our team’s expertise, these outdoor spaces are ready to be enjoyed for years to come.
