If a picture is worth a thousand words, video must be even better right? Check out this brief video demonstration explaining how we raise sunken concrete with our modern polyurethane injection system.

Utilizing the benefits of modern technology, Acme Concrete Raising and Repair is the first concrete raising contractor located in the Chicagoland area focused specifically on raising sunken concrete with polyurethane injections.

Polyurethane easily lifts concrete slabs and provides a very strong support structure under the raised concrete. Our lifting foams will not shrink or expand due to moisture changes, nor will they wash out like aggregate-based slurries used by mudjacking companies.

Our repair process is neat, clean and non-invasive to surrounding areas.

Step 1 – DRILL

First, we drill small, ⅝ inch diameter holes through the sunken concrete at strategic locations and install temporary injection ports.

Step 2 – FILL

Next, we inject a two-part expanding foam polymer through the injection ports.  This fills voids while raising, thus leveling the sunken slab.

Step 3 – PATCH

Finally, the injection ports are removed and the holes are patched with cement, leaving the repair virtually unnoticeable.
