NV Waterproofing & Foundation Repair Before & After Photos

A homeowner in Fort Washington, MD was dealing with an uneven concrete driveway at the garage entrance, creating a safety hazard for vehicles and a frustrating daily inconvenience — a common issue across Northern Virginia, Maryland, and Washington, DC. Our concrete leveling specialists used the PolyLevel® polyurethane foam system to lift and stabilize the sunken slab with precision, restoring proper alignment and creating a smooth transition into the garage without the disruption of full concrete replacement.

To protect the repair and prevent future settling, we sealed the joints and cracks with NexusPro®, blocking water intrusion that often causes concrete to shift over time. The result is a safer, more functional driveway with improved curb appeal and long-lasting durability. If your garage entrance or driveway is uneven in VA, MD, or DC, professional concrete lifting and sealing offers a fast, affordable solution that extends the life of your concrete.

Flipping a house in La Plata, MD, often presents a range of challenges, especially when dealing with basement foundation cracks and persistent water issues. In this particular project, the basement required a complete overhaul to address both interior and exterior waterproofing concerns to ensure long-term stability and dryness.

To tackle these issues head-on, our expert team at NV Waterproofing and Foundation Repair implemented a comprehensive solution. We installed the WaterGuard Perimeter Drainage System around the foundation to efficiently collect and channel water away from the basement. In addition, we used CleanSpace Crawl Space Encapsulation to create a moisture-resistant barrier that keeps the area dry and free from harmful humidity. To top it off, we added the high-performance TripleSafe Sump Pump to provide reliable, year-round water removal, ensuring the basement stays dry even during heavy rainfall.

The results speak for themselves: the after shot reveals a transformed basement—completely dry, structurally sound, and ready for its next phase. With these smart, durable solutions, the basement is not only protected from future water damage but also reinforced for years to come. This dependable waterproofing system makes the property a solid investment for any house flipper in La Plata, MD.

A homeowner in Burtonsville, Maryland reached out to us after noticing their concrete front stoop had started to slope and sink. There were clear voids underneath the porch, which caused the surface to become uneven and raised concerns about safety and long-term damage.

After taking a look, we recommended concrete leveling to lift and stabilize the porch. Using PolyLevel, we were able to raise the stoop back into place while filling the empty space below to properly support it. We also sealed the cracks with NexusPro to help prevent water from getting in and causing further issues.

This concrete repair gave the homeowner a safe, level entryway again—without the need to replace the entire structure. If you’re dealing with something similar, our concrete porch leveling solutions can help restore your concrete quickly and effectively
