Concrete is a heavy material and so are the structures that concrete slabs and footings are expected to support. Sometimes, the combined weight of concrete and what it supports causes concrete settlement to occur. The soil beneath the concrete compresses and can cause major problems, including tripping hazards.
PolyLevel® is designed specifically to repair this type of problem in Portsmouth, Lewiston, Waterville, Dover, Auburn, Biddeford, South Portland and other nearby areas.
We can help you eliminate tripping hazards with our quick and reliable interior slab leveling solution, as seen in this garage.
In the past, contractors often raised settled concrete by pumping a liquid mortar beneath the settled section (called mud jacking). But this pumping process is hard to control, and the added mass of the mortar puts even more weight on the soil.
Fortunately, foundation and concrete repair specialists now have a new technique that's more effective at raising settled concrete. Polymer injection harnesses the expansive force of a structural grade geopolymer to provide fast concrete leveling, fill voids in soil and strengthen soil that has poor load-bearing qualities.
The polymer consists of two separate liquids that are combined right at the injection nozzle to trigger a chemical reaction that turns the blended ingredients into expanding, high-density foam. The foam flows into voids and between loose soil particles, expanding to about 15 times its initial volume. This expansive action effectively lifts settled concrete. An experienced technician, like those at TC Hafford Basement Systems, can control the application to create just the right amount of raising pressure.
The polymer begins to harden quickly after doing its raising work. Within just 30 minutes, it reaches 90% of its final strength, enabling damaged concrete slabs to be put back into service right away. The speed of polymer injection repairs is another huge advantage over mortar pumping.
