LongCrete Polyurethane Concrete Lifting

Working in this field, often we find that many of our seemingly small jobs like this one actually have quite the void underneath the concrete. It is important to take any area of sinking concrete seriously, as this is most often caused by ongoing issues such as misdirected water drainage or sewer leaks. In these cases, the consequences of waiting can be expensive and can even get so bad that replacement becomes the only option available.

The use of rebar as a structural support to prevent shifting, cracking and sinking . Often when concrete begins to sink this rebar has either failed completely or is at the beginning stages of failure. Rebar often fails due to a void that puts extra stress on the rebar. In the case that rebar fails, it is possible the broken pieces will need to be cut to prevent the concrete from catching as it is lifted. Many of our clients fear cutting the rebar will cause the concrete to fail again, however it is important to note that if we are at the point where we need to cut the rebar it has already failed. That’s why our polyurethane is engineered to be able to fill the void beneath, and compact the dirt around to provide for a stable, secure foundation.

In the case of either rebar or our polyurethane foam, both can fail to support the concrete if a water drainage issue creates a void underneath the structural support. Our foam does not wash out from water however the soil around it is still susceptible to erosion if a water drainage issue is not fixed after our services. Our warranty does not cover concrete failing due to any water drainage issue, etc that were not fixed the first time around.
