Resin injection underpinning in Melbourne lifts and stabilises a home by injecting expanding structural resin into the soil beneath the footing, with no excavation. The resin expands, compacts the weak soil and raises the footing back to level, often in a single day. It is the least invasive underpinning method, which suits slab homes and occupied buildings.
It is not right for every home. We inspect the soil and the movement first, and only recommend resin when it genuinely suits your ground.
What is resin injection underpinning?
It is a method that stabilises and lifts a foundation by injecting a two-part expanding resin through small holes into the soil below. As the resin cures it expands, filling voids, compacting soft soil and gently raising the footing. Because it works through holes the size of a pen, there is no trenching and little disruption.
How the process works
Small injection tubes are placed at set points under the footing. Resin is injected in controlled stages while a laser level watches the floor, so the lift is precise. Once the target level is reached, injection stops and the resin cures within minutes. The result is checked against the laser to confirm the correction.
When it is the right method (and when it is not)
Resin suits slab-on-ground homes, compact sites and occupied buildings where digging is impractical. It is less suited to very deep soft soils or homes on stumps, where screw pile underpinning or restumping melbourne is the better call. We will tell you straight if resin is not the right fit.
Cost of resin injection underpinning
As an indicative Melbourne range, resin injection commonly runs from around $6,000 to $20,000, priced by the volume of resin and the area lifted rather than by digging. Compare methods in our underpinning cost guide.

Frequently asked questions
Common questions about resin injection underpinning. Still unsure? Call 04XX XXX XXX.
How does resin injection underpinning work?
Expanding structural resin is injected through small holes into the soil under the footing, where it expands to compact the soil and lift the footing back to level. Bedrock Foundations watches the floor with a laser during the lift so the correction is precise.
Is resin injection as strong as concrete underpinning?
For the right soil conditions it is a proven, engineered solution, though very deep or soft soils are often better suited to screw piles or mass concrete. Bedrock Foundations recommends resin only when your ground genuinely suits it.
How much does resin injection underpinning cost?
As an indicative Melbourne range it is about $6,000 to $20,000, depending on the resin volume and the area being lifted. Bedrock Foundations gives you a fixed written price after a free inspection. Call 04XX XXX XXX.
How long does resin injection take?
Many resin jobs are completed in a single day with almost no mess, since there is no digging. Bedrock Foundations confirms the timeline for your home with your fixed quote.
