Over time, a homeowner in Williamstown, NJ, grew increasingly worried about the risks posed by concrete settlement around their driveway and front sidewalk. The uneven slabs were not only affecting the curb appeal of their property but also creating potential tripping hazards for family and visitors. Realizing the issue could worsen over time, they reached out to Quality 1st for a reliable, long-term solution to restore safety and appearance.

Our team responded promptly and implemented a proven repair strategy using our ultra-stabilizing PolyLevel Foam Injections to lift and level the sunken concrete. This high-density foam expands beneath the surface to fill voids and support the slab, ensuring a durable and even result. To further protect the area, we sealed joints and cracks with NexusPro, a UV-resistant joint sealant designed to prevent water intrusion and erosion.

The combination of these two advanced systems effectively stopped further settlement and restored the driveway and sidewalk to a smooth, safe, and visually appealing condition!

Recently in Williamstown, NJ, a homeowner grew increasingly concerned as their driveway began to show signs of persistent concrete settlement. Uneven surfaces and widening cracks created not only an eyesore but also potential safety hazards. Wanting a permanent and effective fix, the homeowner reached out to Quality 1st for help. We quickly scheduled an inspection, and one of our System Design Specialists conducted a thorough evaluation of the driveway to determine the root cause and develop the most efficient solution.

Based on the inspection results, our team implemented a customized repair plan utilizing two of our most trusted products: PolyLevel Foam Injections and NexusPro Joint Sealant. PolyLevel was injected beneath the sunken slabs to lift and stabilize the concrete, providing a strong, long-lasting foundation. To further protect the repair, we sealed the joints and cracks with UV-resistant NexusPro, which blocks out moisture and prevents future erosion.

The result was a smooth, level, and durable driveway that not only resolved the settlement issue but also gave the homeowner peace of mind knowing the problem was fixed for the long term!

Concrete slabs sink and settle when the soil beneath it can no loner support the weight. Our concrete lifting and leveling solution known as PolyLevel, provides the concrete with the additional support it needs to prevent future settlement.
