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.
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.
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.
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.
