Polyurethane Slab lifting

Uneven concrete, sunken slabs or shifting ground are not just inconvenient. They affect the safety, look and value of your property. Our high-performance polyurethane slab lifting foam offers a fast, clean fix. Injected beneath the surface, this expanding polyurethane resin lifts and relevels slabs with precision, stabilising the ground and restoring confidence, without excavation, heavy machinery or long delays.

Whether you’re a homeowner worried about cracks or a builder needing a reliable fix, we deliver solid results that last.

How Polyurethane Slab Lifting Foam Works

Our slab lifting process is fast, precise, and non-invasive, ideal for fixing sunken concrete on clay-rich ground.

  • Site Inspection: We assess the affected area and identify the cause of movement or voids beneath the slab or concrete.
  • Small Access Holes: Tiny holes are drilled into the slab / concrete, no digging or mess required.
  • Foam Injection: We inject expanding polyurethane resin beneath the slab. The foam flows into voids and expands, gently lifting the concrete back into place.
  • Ground Stabilisation: As the foam hardens, it compresses surrounding soil and locks the slab / concrete into place, providing long-term stability.
  • Ready in Hours: The area is ready to use within hours, no waiting days for concrete to cure or repairs to dry.

What Is Polyurethane Used For?

Polyurethane is a tough, versatile material used in everything from insulation and sealants to furniture and footwear, but in construction and ground engineering, it plays a powerful role beneath the surface.

In slab lifting, we use a high-density polyurethane foam that expands when injected underground. It fills voids, lifts sunken concrete, and compresses surrounding soil to stabilise the ground. Because it sets quickly and needs little equipment, it suits tight spaces, busy sites and residential areas where digging is not practical.

Thanks to its strength, water resistance, and long lifespan, polyurethane is trusted for structural support, void filling, ground consolidation, and even reducing vibration in road and rail infrastructure. For Perth’s reactive soils, it’s a smart, clean solution that delivers results without the mess.

It depends on the job, but most residential work takes between 1-3 days, depending on the job size and ground conditions. We’ll let you know upfront what to expect after inspecting the site.

Not at all. We drill a few small holes, and we patch them once the job’s done. There’s no heavy equipment and no need to break anything up.

Yes. It’s made right here in Australia and meets low-VOC standards, with no ozone-depleting substances. It’s a cleaner choice all round.

The foam hardens into a strong, water-resistant material that holds up for years. It won’t wash away or break down under normal conditions.

It can, and that’s one of the reasons we use it. Perth’s reactive clay can be tough on concrete, and the foam helps stabilise and support it long-term.

Polyurethane is a type of resin, so the terms are often used interchangeably. When people talk about resin injection or resin foam, they’re usually referring to polyurethane. It’s the material we use to lift slabs and stabilise the ground.
