GeoPoly resin injection through small holes in sunken concrete slab

The concrete floor’s dropped, doors are sticking, and cracks have appeared in the walls and ceilings — all at once. The first quote you get is to rip up the slab and repour. That’s $30,000 to $50,000, weeks of work, and a hole in the ground where the floor used to be. There’s a cheaper way — but until you know the ballpark, it’s hard to know whether the first quote is fair or just the only option you’ve been given.

This guide lays out what concrete relevelling actually costs and what makes the price move. No commitment — just a starting point so you know what’s reasonable before someone hands you a number.

What affects the cost of concrete relevelling

The cost of concrete relevelling depends on the size of the slab, how far it’s sunk, and what’s beneath it.

A garage floor that’s dropped 20mm at one edge is a different job to a 60-square-metre ground-floor slab that’s sunk 50mm across half its span. The number of injection holes, the volume of GeoPoly™ resin, and the lift distance all scale with the slab. That’s why the approximate cost of concrete relevelling sits between $4,000 and $14,000.

If you've noticed sunken concrete slabs in your home, the alternative — breaking up the floor and repouring — is a different kind of job entirely. Jackhammers, skip bins, new formwork, fresh concrete, curing time. The cost of slab replacement typically starts at $30,000 and runs well past $50,000 for larger floors. And you're without a usable surface for weeks.

The cost of concrete relevelling with GeoPoly™ avoids all of that. Coin-sized holes. Resin injected. Slab lifts. Holes patched. Done in a day. The floor stays intact.

Fixed pricing

Concrete relevelling quotes based on resin volume are the ones to watch. The cost is quoted at a per-kilo rate with a resin cap. If the voids beneath the slab are larger than estimated — and they usually are — the cap gets exceeded and the price jumps.

Buildfix quotes the cost of concrete relevelling as a fixed price. Unlimited resin. If the voids swallow 310kg instead of 160kg, the quote doesn't change. The slab gets relevelled. The price holds.
