A geopolymer resin made by Buildfix, specifically formulated for lifting sunken concrete slabs, driveways, paths, and pool surrounds. It’s injected beneath the concrete through coin-sized holes, expands to 20 times its volume, and sets into a solid, load-bearing mass in 2 minutes. Not a foam — a permanent mineral-based resin.

Yes. GeoPoly™ SJ120 is injected beneath the slab, filling the voids that caused it to sink and lifting the concrete back towards level. No jackhammering, no repouring, no waiting weeks for new concrete to cure. The existing slab stays — it’s just put back where it belongs.

Most GeoPoly™ SJ120 slab jacking repairs are completed in a few hours to a single day, depending on the area and severity of the settlement. You can walk on the concrete the same day — and drive on driveways within 24 hours.

Every home is different — the slab size, the depth of the drop, and what's beneath it all shape the cost. For an approximate price range and what's involved, see the concrete relevelling pricing guide. A fixed-price quote is provided after the free assessment. The price you see is the price you pay.
