PolyLevel Evens Out Walkway in Kentwood, MI

Sinking sidewalks occur when the pressure from concrete slabs are too much for the soil underneath to bear. Notice how in the before picture the slab appears to slant downwards as it reaches the wall. Most methods for treating sinking slabs are temporary, be they replacing the concrete or slab jacking – pumping a mixture of mud and cement below the slab. These methods don’t treat the root cause of sinking concrete, the soil below; and, often times, the resulting repair may be as uneven as before. That is why here at Ayers we use the PolyLevel injection system. By pumping an expanding polymer foam below the surface of the concrete, we can provide a more stable support system to sidewalks like these.

The crew injected the PolyLevel directly into each of the settling slabs and pumped the polymer until it filled in the voids left by the settling soil. Once the waterproof polymer raised the slab to a leveled height, the injection was ended and the clean-up process began. Thanks to a simple 2-day injection, this walkway will remain at a leveled height without the threat of sinking any lower.
