Raising Concrete with Confidence
When pumping a light-weight material beneath a slab, you need the confidence that it is strong enough for the application. How strong is strong enough? This is a commonly asked question by contractors that are new to slab jacking with polyurethane (also known as poly jacking or foam jacking). Foams only need to be as strong as the dirt beneath, but they’re actually stronger than crystalline bedrock.
Foam Compared to Clay and Bedrock
To put that into perspective, the National Home Builders Association and the International Building Code lists stiff clay at 4000 psf and crystalline bedrock as having 12000 psf of load bearing capacity. Consider the job site conditions where the foam will be injected into a confined area. Testing data in the lab shows that our lifting foams will increase in compressive strength: In a space confined 25% by volume there will be an increase of 31% in psi and in a space confined by 75% there will be a 79% increase in the psi.
Slab Jacking for Any Job with the Right Foam
Today polyurethane lifting foams are used to level airport slabs supporting jumbo jets, equipment and building slabs supporting tremendous loads, and even railway sleepers that support the heaviest freight trains. So don’t let the word “foam” fool you. These resins cure to strengths beyond what is needed to support any structure.

SUNKEN, UNEVEN OR CRACKED
CONCRETE? POLYPRO HAS THE SOLUTION.
We can repair your sinking slab
What if you could raise a cracked or sunken slab back to its proper level in less than an hour, with no “down” time waiting for new concrete or mortar to cure? This fast, affordable repair is possible with the PolyPro concrete leveling system. The PolyPro process involves drilling one or more small holes in the low area of the slab, then injecting an expanding polyurethane foam beneath.
As the foam expands due to a chemical reaction, it pushes the slab back towards its original position. An experienced PolyPro technician can gauge the expanding action of the foam, controlling the injection process for just the right degree of slab-raising action.
Because the injected polymer material cures quickly, the restored slab can return to its full weight-bearing function within a matter of minutes. Slab repair costs through the PolyPro system are far less than replacing the concrete slab altogether. Get a Free Estimate today!
The Right Strengths for Concrete Lifting
Slab lifting foams are rated on density (weight per cubic feet) and compressive strength. This testing and rating is based on the foam in a free rise state; the parts A and B are mixed together and allowed to expand freely. Our structural lifting foams, for example, will weigh from approximately 2 lbs (RR201) to 5 lbs (RR501) per cubic foot. But they have a compressive strengths of 50 psi and 100 psi in a free rise state. That’s equal to 7,200 to14,000 lbs per square ft of support, just in a free rise state.
