How Does It Work?
Drilling for Access
Step 1
Our technicians start by drilling small 16mm holes—no bigger than a penny—in the affected areas. We then install a pipe system at varying depths to prepare for the resin injection.
Injecting the Resin
Step 2
Next, we inject our GeoPoly™ resin through the installed pipe system. The resin follows the path of least resistance, filling any voids and aerated soil in the subsided areas.
Instant Stabilisation and Lift
Step 3
Within just 15 minutes, the resin expands and solidifies, stabilising the ground beneath the affected area. By this time, it’s already 90% cured, offering immediate support to your slabs.
Immediate Results
Step 4
You’ll notice the difference straight away. Cracks may close, floors even out, and jammed doors will now open and close smoothly as your slabs are leveled and stabilised.
Clean-up
Step 5
Once we’ve reached the required level, we remove the pipes and fill any drill holes, ensuring a clean and neat finish with minimal impact on your home and garden.
The Benefits.
Here’s what you can expect from our GeoPoly™ resin injections:
Immediate Stability and Support
Resin injections provide instant stabilisation of
your concrete slabs, preventing further sinking or shifting.
Cracks and Gaps Close Up
As your slabs are levelled, existing cracks and gaps may close-up, improving their appearance instantly.
Smooth Door Function
Doors around affected areas may open and close easily, with no more sticking due to misalignment.
Even Floors and Surfaces
Level and stable floors throughout affected areas, eliminating any slopes, trip hazards or uneven surfaces.

Will my concrete slab become level after lifting?
Buildfix aims to stabilise the soil under your concrete slab to halt any further sinking. Often, our GeoPoly™ technology can successfully lift and level the slab. However, outcomes can vary as they are determined by site-specific conditions.
Why is GeoPoly™ better than other similar resins?
Our advanced GeoPoly™ resin is uniquely developed and manufactured by Buildfix in Australia. As the only foundation repair company with the rights to its own formulation, we have complete control over its production and quality, ensuring it meets the highest standards.
Other resins on the market are supplied by third parties, often from overseas, and their contractors simply can’t offer the same level of assurance as Buildfix.
GeoPoly™ is engineered for exceptional lifting capacity, designed to stabilise and raise even the most challenging areas. Blended in our Sydney facility and tested by our in-house chemists, its proven durability ensures long-lasting performance.
This approach is an Australian first—and potentially a world first—in foundation repair. No other company can match our level of expertise.
With unmatched quality, strength, and durability, GeoPoly™ is the most advanced and reliable solution for lifting your concrete slabs.

Is the job done in just 1-2 days?
Mostly, yes. The majority of our projects are completed within a day. However, the duration varies depending on the complexity of the repair, the area size, and the ground conditions.
What does it cost?
The cost of sinking concrete slabs depends on your home’s specific needs and the extent of the issue. Most residential projects fall within $5k to $20k.
We provide fixed-price quotes, ensuring complete transparency from the start. With Buildfix, there are no questionable sales tactics or surprise costs. We’ll let you know exactly what needs to be done and what it will cost upfront.
Be cautious if a foundation repair company provides an estimate based on the amount of resin used. This can be a bait tactic, luring you into paying extra per kilogram, which ultimately leads to higher costs on the day of repair.
