Concrete rests on subgrade, which is a fancy term for the earth below.  When the subgrade begins to weaken and settle, the Concrete loses its support.  This can be caused by a variety of factors…weather, rain, leaks, excess weight to name a few.  While the root causes may vary, the end result is always the same.  Structural damage.

Over time, often in months, concrete begin to stress, then crack and, eventually, break apart and sink.  This leads to trip hazards, unsightly appearance and a reduction in property values.  This damage is structural – not cosmetic.  Neither patching nor a new surface will solve the problem.

At Poly Lift USA we offer customers an environmentally safe, affordable, long-term resolution.

Our Foamjection technology has enabled thousands of property owners in Florida, Georgia and Texas to repair their damaged driveway and save thousands in replacement costs.  Our typical repair is well under 50% less than cost of replacement.

Here’s how Foamjection technology works:

1. Penny size holes are drilled through the damaged slab at 5-foot intervals.
2. Specially formulated polyurethane foam is pumped through the slab reaching the subgrade underneath.
3. The liquid foam fills voids and expands rapidly to compact the earth beneath the slab.
4. As the foam hardens it locks the slab in place.  We call this stabilization.
5. When lift is required, additional foam is pumped using carefully calibrated pressure gauges until the slab is raised to the desired height.
6. Drill holes are filled with sanded concrete.
