Sidewalk Lifting and Repair in Leesburg, VA

A homeowner in Leesburg, VA, was dealing with a frustrating and all-too-common issue: a sinking concrete step. This uneven step created an awkward and potentially dangerous drop from the main stoop, making it less than ideal for welcoming family and guests. To solve the problem, we turned to our reliable PolyLevel® system, which uses high-strength, strategically-placed foam to lift and level the concrete step back into place. But we didn’t stop there! To ensure long-lasting protection, we applied NexusPro® Joint Sealant, which prevents moisture from seeping in and causing further damage. The result? A perfectly level, safe, and welcoming step that restores both functionality and peace of mind. If you’re dealing with a sinking concrete step in Leesburg, VA, contact us today to learn how PolyLevel® and NexusPro® can provide a durable and effective solution!

Driveway Repair in Aldie, VA: Reliable Concrete Leveling & Waterproofing Solution

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. At NV Waterproofing and Foundation Repair, we addressed the issue using our trusted NexusPro Joint Sealant—a highly effective, waterproof solution that fills joints and helps prevent water from seeping beneath the surface. By sealing the gaps and improving water runoff, we help protect the driveway and surrounding foundation from future erosion. The after photo shows a clean, level surface that reflects our commitment to quality results and long-term protection for homes throughout Aldie and the surrounding area.
