Before & After Photos

This customer had issues with ground settlement and washouts. These things caused voids in the ground under the concrete thus caused cracking on the sidewalk. Our crew used Polylevel 400 to lift as much as Structure will allow, stabilization 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.

This Nashville homeowner noticed the concrete sidewalk outside of his home sinking more and more every year. It was a huge tripping hazard that  he did not want to worry about anymore, so he decided to find a company that could lift and seal it once and for all.. and for a good price! 

After our inspector came to look over the sinking slab and discussed our trusted solutions, our very experienced foreman came to repair the sidewalk! 
We used PolyLevel to lift the slab up and used NexusPro Joint Sealant to seal the cracks so water would not infiltrate the slab! 

Details about our products:

PolyLevel is an expanding polyurethane foam that is injected beneath the concrete to fill the gaps caused by soil erosion and raise and stabilize the concrete surface.

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.

This homeowner now has a peace of mind and lifted concrete slab! 

Most concrete problems are caused by poor soil. Soil can soften due to excessive moisture, shrink due to drought or become unstable because of inadequate initial compaction. These situations cause voids to form, which in turn allows the heavy concrete above to sink and become uneven. As concrete slabs sink, they can crack and break, creating jagged, raised edges that are not only an eyesore but also potentially dangerous.

Our team used PolyLevel to lift the sunken slab and NexusPro to seal the crack.

A large porch is a staple in the South. where tons of heart to hearts and memories are made. In Cookeville this large patio porch had began to sink and needed a lift. PolyLevel concrete injection is a permanent solution to raise the concrete preventing trip hazards or pooling water; safer for the structure and the family.
