Polyurethane Concrete Slab Lifting in Perth by UpSlab.com.au

Concrete settlement is a common issue across Perth and Western Australia. Over time, factors like poor soil compaction, erosion, tree roots, or water leaks can cause slabs to sink or crack. Traditionally, the only way to fix these problems was to remove and replace the damaged concrete — a process that’s expensive, messy, and time-consuming.

UpSlab.com.au, is one of the leading experts, provides a modern alternative: polyurethane concrete slab lifting/slab jacking. This innovative method restores uneven or sunken concrete surfaces quickly and effectively using high-density expanding foam technology.

How the Technology Works

The process begins with drilling small holes (about the size of a 5-cent coin) into the affected slab. Through these holes, a two-part polyurethane mixture is injected beneath the surface. When the polyol (Part A) and isocyanate (Part B) components mix, they react and expand, forming a lightweight but incredibly strong foam.

This foam fills any voids or gaps under the slab, stabilizes the base soil, and gently lifts the concrete back to its original level. Once the desired lift is achieved, the holes are patched, and the surface is ready for immediate use — often within minutes.

Advantages of Polyurethane Slab Lifting

• Fast and Clean – Most projects are completed within a few hours, with no heavy machinery or long curing times.
• Cost-Effective – Lifting existing slabs costs a fraction of full replacement.
• Lightweight and Strong – The foam adds minimal weight to the soil while providing exceptional compressive strength.
• Water-Resistant – Polyurethane is impervious to moisture, helping prevent future soil erosion and slab movement.
• Environmentally Friendly – The process uses minimal materials and reduces waste by extending the life of existing concrete.
• Long-Lasting Results – Once cured, the foam remains stable for decades, even in Perth’s sandy and clay-based soils.
