This wasn't your everyday basement waterproofing job. The homeowner was facing issues due to water infiltrating their underground living space, requiring an innovative and effective solution. After contacting our Customer Care team, we scheduled a home inspection to better understand the nature of their dilemma. Our System Design Specialist visited the home, conducting a thorough analysis of the situation.

A homeowner in Frederick, MD recently faced a common yet serious issue of bowing walls in their basement. This concern led them to contact us at NV Waterproofing & Foundation Repair, recognizing a potential sign of foundation failure that needed immediate attention.

Unlevel sidewalks are a common concern for homeowners in Knoxville, MD, due to their potential to cause safety hazards and legal liabilities. This issue not only detracts from a property's curb appeal but also poses a serious risk of trips and falls. When one local homeowner noticed the uneven concrete slabs around their property, they chose NV Waterproofing & Foundation Repair for a solution they could trust. After a seamless consultation with our Customer Care Specialist, a detailed inspection by a System Design Specialist revealed the best approach to lift and stabilize the slabs involved using the industry-leading PolyLevel® system, supplemented by NexusPro® Joint Sealant for long-term durability.
To tackle the uneven surfaces, our skilled production team began with the precision-based PolyLevel® technique. This innovative method involved drilling small, strategically placed holes into the affected sidewalks and filling them with high-strength polyurethane foam. As the foam expanded beneath the concrete, it gently lifted the slabs back to their original, level position. This process was quick, non-invasive, and provided a permanent solution to counteract future settling. To enhance the effectiveness of the repair and protect the concrete against water infiltration, NexusPro® Joint Sealant was carefully applied. This advanced sealant creates a durable barrier that resists cracking and erosion caused by weather variations, ensuring the sidewalks remain level and intact for years to come.
The result was a smooth, even sidewalk that restored the homeowner's peace of mind and the property's visual appeal.
