GeoPoly™ — Resin injection that stabilises and lifts your home's foundation.

Non-Invasive. Permanent. Guaranteed.

Targets shifting, eroding ground. Foundation lifted — stabilised permanently.

Foundation problems happen deep underground — reactive clay receding, water pooling, tree roots breaking up the soil. Almost impossible to detect from the surface. Traditionally the only fix was digging large holes beneath your footings and pumping in concrete — that's concrete underpinning, with council approvals, certifiers, and six-figure quotes for many homeowners. GeoPoly™ resin injection does the same job, without the dig. And at a fraction of the cost.

It's like keyhole surgery for your foundation. Small, coin-sized holes are drilled around the affected areas, then engineered resin is injected at precise depths beneath your home. The resin expands, fills voids and weak spots in the soil, and lifts your foundation to its target level — every millimetre of the lift monitored in real time with laser levelling.

Your home's piers, slab or footings haven't failed. The ground beneath them has. As the soil compacts and your foundation lifts to the ideal level, you'll see floor levels returning, cracks and gaps closing before your eyes. The whole job typically takes a day or two — and often it's done in less than a day.

Not sure what's going on beneath your home? That's exactly what the free assessment answers.

Repair details — with photos, markings, and measurements — are created on-site using our mobile software, and the price can usually be explained there and then, so you know exactly where you stand.

Lift and Level Your Foundation

On the scheduled day, our technicians arrive and get straight to work. Small, coin-sized holes are drilled around the problem areas, then GeoPoly™ resin is injected at precise depths beneath your home. The resin expands, fills voids and weak spots, and lifts your foundation to its ideal level — with laser levelling equipment monitoring every millimetre of the lift in real time.

Patch and Clean Up

The benefits of a GeoPoly™ foundation repair.

GeoPoly™ resin is injected 2+ metres beneath your foundations and monitored in real time with laser levelling equipment and digital sensors. As the resin expands, it fills voids, compacts weak ground, and lifts your foundation to its ideal level — every millimetre of the lift controlled, not guessed at. You’ll notice cracks closing, gaps shrinking, and doors that were sticking working again.
