  • PolyLevel Assists in Home Improvement Efforts in Inman, SC
    PolyLevel Assists in Home Improvement Efforts in Inman, SC

    Tim W. has been a resident and homeowner in Inman, SC for most of his adult life. He and his wife recently retired which gave them extra time on their hands. Through the years they were not able to do everything they wanted in regards to renovations on their home. Working full time and raising children did not leave much time for home improvement. Tim and his wife have been enjoying finally doing different projects around their home. Tim had noticed a while ago that their back concrete porch was sinking. He did not want the hassle of completely replacing the concrete slab so he looked for alternatives. One morning while watching the news Tim saw a commercial for Cantey Foundation Specialists. He called in to see if Cantey could help him with his porch. System Design Specialist Ryan Holloway came out for an inspection and found that the PolyLevel process that Cantey offers would be the right solution. Ryan explained to Tim that small holes would be drilled through the slab. These would be the places that the PolyLevel would be injected. The PolyLevel would come out as a liquid effectively filling any voids underneath the concrete. Within 15 minutes the liquid would solidify and as it did it would be constructing a solid foundation and lifting the concrete slab. Production Team Leader Roberto Buchner came out and successfully injected the PolyLevel process. Tim and his wife are more than pleased with their porch and are now recommending Cantey to all their friends.

    PolyLevel Saves Children from Tripping Hazard in Inman, SC

    Vic and Tricia B. have been homeowners in Inman, SC for the last few years. They bought a new home where they plan to stay to raise their children. The kids love playing outside so Vic and Tricia specifically bought a home that had a huge front and backyard. Recently, one of the kids tripped over the sidewalk leading up to the front steps. Vic and Tricia had not previously noticed that their concrete slab leading up to the door had started to sink. They were concerned about the safety of their children as they played outside. Immediately Vic began to look for a company that could solve this tripping hazard. During his search online he came across Cantey Foundation Specialists and their PolyLevel process. Vic and Tricia decided they would make an appointment to have someone come out and inspect. System Design Specialist Ryan Holloway arrived for the appointment and inspected the area in question. Ryan sat down with Vic and Tricia to let them know that he thought the PolyLevel process was the right solution for them. The PolyLevel process would begin with small holes being drilled through the concrete slab. These would be the injection sites for the liquid PolyLevel that would find all the voids and fill them. Once the PolyLevel was injected, it would take 15 minutes to harden. As the PolyLevel sets, it lifts the concrete slab above while stabilizing underneath the slab. Vic and Tricia now have the peace of mind that their children are safe to play outside once again thanks to Cantey's PolyLevel solution.

How PolyLevel® Works

The causes of concrete settlement and sinking are the same whether it's a driveway, walkway, patio, garage floor, or pool deck. As soil underneath a concrete slab shrinks, settles or washes away, this leaves empty space, or voids, beneath the slab. With the soil no longer supporting the slab, the concrete will sink, creating an uneven surface.

PolyLevel uses a high-density polyurethane foam to fill voids and stabilize and lift sinking concrete slabs. The expanding properties of the two-part urethane formula allows for accurate leveling of the slab. The result is a waterproof repair that's much more permanent than mudjacking and other common concrete repair methods.

PolyLevel step 1: drilling injection holes


Small 5/8" holes are strategically drilled in the slab.

PolyLevel step 2: installing injection ports


Injection ports are installed.

PolyLevel step 3: injecting polyurethane foam


Polyurethane foam is injected beneath the concrete to fill voids and raise the slab.

PolyLevel step 4: sealing holes and control joints


Holes and control joints are sealed.

PolyLevel® Applications

Traditional Concrete Lifting vs PolyLevel®

Before PolyLevel, there were two basic options for lifting and leveling concrete: mudjacking and slab replacement. Both approaches have limitations and disadvantages. PolyLevel offers many advantages over traditional concrete leveling methods:


Foam Injection
Mudjacking or Slabjacking
Cure Time 15 minutes 24 hours or more
Material Weight 2 lbs per cubic foot 100 lbs per cubic foot
Hole Size 5/8" (size of a penny) 1" (size of a quarter)
Waterproof Yes No

Concrete Replacement

Replacing a concrete slab is both expensive and disruptive. Concrete slabs can take days - or even weeks - to cure. Pouring new concrete over bad soil often delays future problems and leaves unsightly patchwork. PolyLevel material is lightweight, so it won't add weight to weak soil. Best of all, PolyLevel allows for use of concrete within hours, not weeks.

If your concrete is structurally-sound, why replace it? Replacing the concrete won't fix the soil problem that's causing the settlement. Concrete leveling is the answer.
