Need a Big Bang for Your Buck? Consider Repairing Your Sidewalk.

 

poly repair

Fixing your sidewalks is one of the best home improvement projects you can make. It’s been listed as one of the top 10 improvements you can do to your home. We know it’s not an improvement that is as alluring as some of the others on your list, but it does go a long way toward improving the safety and look of your home.

Pouring new concrete may not be necessary. 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 Davenport Foundation Repair, 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 roads and slabs to be put back into service right away. The speed of polymer injection repairs is another huge advantage over mortar pumping.

In addition to lifting and realigning settled and/or shifted concrete, polymer injection can be done prior to construction to improve soil stability and strength. Injections as deep as 20ft.-30ft. are possible.
