Concrete Leveling & Repair with PolyLevel

Concrete can settle when the soil beneath a slab shifts, compresses, or washes away. Warning signs include uneven sidewalk sections, sinking steps or patios, widening cracks, water draining toward the home, and gaps beneath the slab. These conditions can create trip hazards and often worsen if the underlying void is not addressed.

Blackburn uses PolyLevel® expanding foam to lift and stabilize eligible concrete slabs. The material is injected through small holes and expands beneath the concrete to fill voids and carefully raise the surface. A professional inspection determines whether lifting is appropriate and how much correction can safely be achieved.

PolyLevel expanding foam can reach voids beneath eligible slabs through small injection holes. As the material expands, trained installers carefully control the lift to help restore a safer, more even surface. Because the foam cures quickly, many repaired areas can return to service sooner than with traditional concrete replacement.

Traditional concrete-lifting methods may use heavy grout or other materials beneath a slab. PolyLevel® uses lightweight expanding foam that can reach voids through small injection holes, allowing trained installers to control the lift while adding less weight to the supporting soil. It also cures quickly, so many repaired areas can return to service sooner.

The right repair depends on the slab’s condition, the cause of settlement, and the surrounding drainage. Blackburn’s concrete specialists inspect the area and explain whether PolyLevel, crack and joint sealing, surface protection, or replacement is the most appropriate option.

Protect Your Concrete from Soil Erosion with Nexus Pro®

NexusPro® is a silicone-based sealant for joints and cracks specially engineered to provide long-lasting flexibility and to stand up to harsh weather conditions. Unlike traditional polyurethane sealants, NexusPro resists UV rays, which means it won’t crack, bubble or dry. It fits into homeowners’ busy lifestyles, too – drying time is a fraction of that needed for other urethane-based caulking products.
