Everything You Need to Know About PolyRenewal™

Sinking, settled, and cracked concrete slabs allow expansive clay soils to retain more water, potentially causing structural problems in your Edmonton home. They also pose a tripping hazard, risking your family’s safety. Mudjacking provides a temporary fix but is messy, washes out quickly, and doesn’t address the root cause of sinking concrete. We recommend a more comprehensive concrete repair method. 

Polyurethane foam injections can lift and level damaged concrete, restoring driveways, sidewalks, and other structures to their original condition. However, you need a lightweight solution that cures quickly and doesn’t release dangerous chemicals into your soil. PolyRenewal™ offers these benefits. Learn more about this proprietary product from Groundworks below. 

What Is PolyRenewal™?

PolyRenewal™ is an expanding foam that addresses the underlying cause of sinking concrete slabs, such as soil erosion, shrinkage, and poor compaction. We can inject it beneath your concrete structures to compress soil, fill cracks, and create more even surfaces. 

Our patented polyurethane foam injections are an alternative to mudjacking, which is invasive, unsightly, and not eco-friendly. We use it to lift and level concrete structures on properties across Alberta. 

How We Install PolyRenewal™

We follow these steps when repairing concrete slabs with PolyRenewal™:

  • Drilling penny-sized holes in concrete slabs
  • Inserting injection ports
  • Preparing the two-part polyurethane solution
  • Injecting the solution into the holes
  • Sealing and smoothing over the injection points
  • Performing annual maintenance checks to increase the lifespan of concrete slabs

When it expands, PolyRenewal™ lets us lift sinking concrete and keep it in one place, resulting in an even surface that’s no longer a trip hazard or risk to your home’s foundation. 

PolyRenewal™ Benefits

PolyRenewal™ offers the following advantages when compared with mudjacking and other traditional concrete lifting methods:

  • Creates a hydrophobic barrier that repels water away from your concrete slabs, preventing settlement and other damage
  • Keeps unwanted chemicals from entering your home if you’ve used too much weed killer or you have a chemical spill in your area
  • Cures in as little as 15 minutes, meaning you can enjoy your concrete structures again shortly after application

PolyRenewal™ won’t solve all concrete problems on your property. However, it offers incredible flexibility, with our team able to fine-tune the foam’s density and expansive force according to your needs.
