Stump lifting is a non-invasive alternative to restumping. If you're seeing signs of sinking floor stumps, expanding resin is injected beneath them to stabilise the ground, fill voids, and gradually lift each stump back into firm contact with the bearer above. The floors level out. The doors close. Done in a day or two.

Here's what 15,000+ jobs have taught us: the stumps are almost never the problem. Concrete stumps are simple, solid posts — 100mm x 100mm, sitting on small pad footings. They hold for decades as long as the ground beneath them holds. When it shifts, the stump drops and loses contact with the bearer. A brand-new stump poured onto the same ground will do the same thing. Stump lifting fixes the ground instead.

If you've been quoted for restumping and you're wondering whether there's an alternative — this is it. GeoPoly™ PSR30 delivers the same structural result. A fraction of the disruption. A fraction of the cost.

Restumping works — when the stump itself has cracked, crumbled, or rotted through. That's a failed stump. Replace it. But most stumps Buildfix sees haven't failed at all. The concrete is sound. The stump is doing exactly what it was built to do. The ground underneath gave way.

Replace a good stump and the new one sits on the same weak soil. The floor drops again. Restumping treats the stump. Stump lifting treats the ground. That's the difference.
