Frequently Asked Questions About PolyLevel

Frequently Asked Questions About PolyLevel - Image 1

TerraFirma’s PolyLevel foam is a one-of-a-kind technology that helps homeowners with their uneven sidewalk, driveway, or patio. Injecting polyurethane foam under a slab that’s settled is a new approach to concrete repair, so it’s understandable that a homeowner would have some questions about PolyLevel and its effects. 

To be transparent and clear up any confusion, we’ve compiled a list of frequently asked questions about PolyLevel.

Is PolyLevel environmentally friendly?

Yes. The polyurethane foam within PolyLevel uses recycled material that is waterproof and won’t deteriorate over time. No harmful chemicals disperse during installation, and the foam doesn’t hurt your soil at all.

How expensive is PolyLevel?

Because TerraFirma provides custom solutions, there is no set price on how much PolyLevel will cost. It is cheaper than completely replacing your concrete, and it is free to have a TerraFirma System Design Specialist come out to your home and inspect your uneven driveway, sidewalk, or patio.

How long does it take for the PolyLevel to work? 

PolyLevel cures quickly, and in most cases, you can drive your car over a driveway slab just 15 minutes after it is lifted with PolyLevel.

How strong is PolyLevel? 

Along with being waterproof, PolyLevel’s lifting force can go up to 6,000 pounds per square foot. Recently, TerraFirma used PolyLevel foam to repair a part of the I-5 highway near Medford, OR. If it’s strong enough to repair your highway, it’s strong enough to repair your driveway.

How is PolyLevel compared to mudjacking?

We want our homeowners to be informed, so we recommend that you research both products and make your own informed decision.

From our experience, PolyLevel is the superior choice for many reasons:

  • Multiple one to two-inch holes are drilled into your concrete in mudjacking. PolyLevel drills fewer holes in your concrete, and the holes are about ⅝ of an inch in diameter.

  • Over time, mudjacking will deteriorate, wash away, and start to settle from constant rainfall. PolyLevel is water-resistant and won’t wash away.

  • The thickness of the “mud” mix in mudjacking means that the material can’t seep into every gap in your soil and stabilize your slab. PolyLevel expands into loose soil under your slab and strengthens the ground to support your concrete.
