How PolyRenewal® Concrete Lifting Works

PolyRenewal® concrete lifting is an expansive, polyurethane foam that is injected underneath sunken concrete slabs. Small holes are drilled through the sunken concrete slab and the pressurized PolyRenewal® foam is sprayed into the hole through a specialized hose and nozzle. The foam quickly expands to fill any empty space below the slab.

As the PolyRenewal® expands, it lifts the sunken slab. The foam is injected through a series of small holes to ensure that the slab is properly lifted. After injection, the drilled holes are filled with a concrete mortar, hiding any evidence of work done. The foam quickly cures, creating a strong foundation for the concrete. The cured foam can easily handle the weight of your car on your driveway. That’s it, you have even concrete.

The Benefits of PolyRenewal Concrete Lifting over other methods

Concrete Grinding

Concrete grinding is a well-known and advertised technique here in Indianapolis. While it may be effective in certain circumstances it is not a good idea for sunken slab repair. Concrete grinding involves taking a disk grinder and shaving off the level concrete slab so it meets the sunken slab. While this does get rid of any exposed edge it also weakens the concrete. It also does nothing to prevent the sunken concrete slab from continuing to sink.

Concrete Resurfacing

Concrete Resurfacing is simply adding a fresh layer of concrete on the sunken slab to create a level surface. Not only is this the most expensive option but it places additional weight on the slab. This is especially an issue for concrete over a weak soil base. The additional weight causes the originally sunken slab to now sink even faster.

Traditional Mudjacking (slab jacking, slab leveling, grout pumping)

PolyRenewal is an updated form of mudjacking. Traditional mudjacking also requires holes to be drilled into the sunken slab, but the holes are much larger. This is because instead of pumping a foam underneath the slab, a thick mud slurry is used instead. The pressurized mud slurry lifts the sunken slab. While this does work, the heavy mud slurry can place additional stress on weak soil bases, resulting in the sunken slab sinking even faster.

PolyRenewal™ is a much lighter but equally strong material for mudjacking. PolyRenewal™ also cures much faster. While you will have to wait days for your driveway to cure with traditional slab jacking, you can park your car in under an hour with PolyRenewal™.
