How does the Resin Injection process work?
Drilling for Access
Step 1
Small, coin-sized holes are drilled directly above the affected piers and stumps. These provide precise access for the injection process without the need to remove floorboards.
Monitoring Lift
Step 2
After the drilling and pipe installation, we set up laser leveling equipment to monitor the lift with millimetre precision. This ensures that the foundation is raised evenly and accurately.
Injecting the Resin
Step 3
Next, we inject our GeoPoly™ resin through the installed pipe system. The resin follows the path of least resistance, filling any voids and lifting the pier.
Instant Stabilisation and Lift
Step 4
Within just 15 minutes, the resin expands and solidifies, stabilising the ground beneath your home. By this time, it’s already 90% cured, offering immediate support to your floor piers.
Immediate Results
Step 5
You’ll notice the difference straight away. Cracks may close, floors even out, and jammed doors will now open and close smoothly as your floor piers are leveled and stabilised.
Clean-up
Step 6
Once we’ve reached the required level, we remove the pipes and fill any drill holes, ensuring a clean and neat finish with minimal impact on your home.
The benefits
Here’s what you can expect from our GeoPoly™ resin injections:
Immediate stability and support
Resin injections provide instant foundation stabilisation under your home, preventing further sinking.
Cracks and gaps close up
As your piers or stumps are raised, existing cracks and gaps can close-up, improving your home’s appearance.
Smooth door function
Doors around your home may open and close easily, with no more sticking or misalignment due to uneven floors.
Even floors and surfaces
Level and stable floors throughout your home, eliminating any slopes, trip hazards or uneven surfaces.

“I wish we got them in sooner!”
They were very thorough with measuring levels as the piers were lifting. Much care was taken when closing up cornices, getting the carpentry plumb and ensuring that all the doors were opening and closing. I wish we got them in sooner!

How does a Buildfix fixed-price quote benefit me?
At Buildfix, we believe in providing you with peace of mind. Our fixed-price quotes include unlimited* GeoPoly™ resin for your job, ensuring there are no surprise charges.

Will the repair process be disruptive and messy?
Not at all. Our precision drilling creates small, coin-sized holes, eliminating the need for messy excavation. Repairs are quick, clean, and minimally invasive—you can stay home with minimal disruption.
Why is resin injection better than replacing piers and stumps?
GeoPoly™ resin injection is faster, cleaner, and more precise than traditional pier or stump replacement. It targets the root cause of sinking floors, stabilising and lifting them immediately. Many homeowners see instant, permanent results.
