Underpinning Melbourne

Underpinning strengthens the foundations beneath a Melbourne home so the structure above stops moving. Cracked walls, sloping floors, doors that won't close — they're all signs the ground beneath the slab or stumps has shifted, and the fix has to address the soil, not just the symptoms above.

Traditional mass concrete underpinning works — done well, it's a real engineering solution. But the Melbourne reality is that most homeowners aren't told upfront how much of their yard, garden and driveway gets dug up. There's a non-invasive alternative.

GeoPoly™ resin injection is Buildfix's underpinning method for Melbourne homes. Coin-sized holes, no digging, the foundation lifted back towards level in 1–2 days. Your home stays liveable. Your garden stays planted. Your driveway stays parked-on.

Melbourne sits on some of the most reactive clay soil in Australia. The black soils across the western suburbs — Werribee, Sunshine, Footscray — move dramatically with the seasons. The clays in the east and north (Box Hill, Doncaster, Diamond Creek) behave the same. Add Melbourne's drought-flood cycles and the ground beneath thousands of homes shifts by several millimetres a year.

The other Melbourne reality is established gardens. A mature tree within 10 metres of a footing draws 200–500 litres of water from the soil a day in summer. Disconnected downpipes pour water against the wall in winter. Cracked clay pipes — common under homes built before 1970 — wash voids in the soil that no one sees until the floor drops. Every job starts with a free on-site assessment that maps the cause before any work is proposed.
