Before & After Photos

Ground settlement causing porch to separate. Crews used Poly Level 400 to lift the porch and provide the homeowner with a level porch and a happy experience.

This homeowner tripped one time too many over their cracked, uneven porch slab and finally had enough. It was time to level out their concrete porch, so they didn't have to watch their step anymore!

Our experienced foreman insert Polylevel into the slab.
The PolyLevel method for lifting and stabilizing a sidewalk or other exterior concrete slab is to inject structural polyurethane foam under the sunken section of concrete. The force of the expanding foam will fill all voids and consolidate weak soils. When the voids are filled, the upward pressure of any additional foam will raise the slab to its original level position.

We also recommend sealing the crack with NexusPro, which 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.

This customer had issues with ground settlement and washouts. These things caused voids in the ground under the concrete, thus causing cracking on the sidewalk. Our crew used Polylevel 400 to lift as much as the structure would allow, and stabilization was guaranteed. Once the voids are filled, the cracks are repaired and sealed using Nexus Pro. Once the repairs are done & the excess Polylevel foam has been trimmed, the customer will be responsible for filling the exposed area with dirt or filler to ensure the erosion does not return.

There is no job too big for Frontier! Our PolyLevel has high-capacity lifting strength, typically lifting from 2000 to 4000 lbs. per square foot.
