What is foundation repair?
Foundation repair is the process of stabilising and relevelling the ground beneath your home's footings — the concrete strips or pads that carry the weight of everything above. When that ground moves, the footings lose support, the house sinks unevenly — what's known as subsidence — and the damage shows up everywhere: cracks in walls, sticking doors, sloping floors.
Here's what most homeowners don't realise: the footings themselves almost never fail. It's the ground beneath them that moves — and once the ground goes, everything above follows. Foundation repair fixes the ground so the footings sit on something solid again.
Modern foundation repair uses GeoPoly™ GER60 expanding geopolymer resin injected through coin-sized holes to fill voids, compact weak soil, and lift the foundation back towards level. The same technology used in underpinning — what used to take weeks of digging and concrete now takes 1–2 days.
Why does a home need foundation repair?
A sinking foundation puts uneven load on everything above it — walls crack, doors jam, floors slope, and gaps open between walls and ceilings. Those symptoms are your home telling you the ground has moved.
Foundation repair stabilises and relevels the ground beneath the footings. As it does, you'll notice cracks starting to close, doors working again, and floors feeling solid underfoot.
The traditional ways of foundation repair a home
Each method works — done right, they’re legitimate engineering solutions. But each comes with trade-offs worth understanding.
The traditional ways of repairing foundations
How foundation repair works with GeoPoly™
Non-Invasive. Permanent. Guaranteed.
No Digging. No Concrete Piers. A Fraction of the Cost.
Your home is sinking because the ground beneath the footings has softened, washed away, or become aerated. Fill that space. Stabilise the ground. Problem solved. That's the principle behind GeoPoly™ foundation repair — it's like keyhole surgery for your home's foundation.
GeoPoly™ resin is injected through coin-sized holes drilled around the problem areas. The resin travels under pressure, targeting the exact point where the movement is occurring. Within minutes it begins to harden, tougher than the original ground, expanding beneath the footings to fill voids and compact weak soil.
As the foundation lifts back towards level, you'll notice cracks closing, gaps shrinking, and doors working again. What used to take months of traditional foundation repair now takes just 1–2 days.
