Commercial-grade technology
Made by Buildfix.
Before and after, on commercial sites.
Council walkways, a research facility and a heritage wall — the lip, the gap, the structural crack, then the fix.

What to expect
Assessment to handover, one company. This is what a commercial job looks like.
Step 1Site assessment
A structural engineer walks the site, takes laser levels and identifies the cause. Written findings with the measurements — not a verbal summary over the phone.
Step 2Engineering design and fixed-price scope
The repair is designed and documented — drawings, specifications, SWMS and the insurance certificates procurement will ask for. One fixed price. No per-kilo resin charges, no allowances.
Step 3Works scheduled around operations
After hours, weekends or staged zones. The injection rig and a small crew are the whole footprint. Doors stay open, staff stay at their desks.
Step 4Laser-monitored lift
GeoPoly™ is injected beneath the slab or footing and the lift is monitored to the millimetre in real time. Crossfalls, thresholds and door clearances are set to target — not to “close enough”.
Step 5Handover pack and 20-year warranty
Completion report, before-and-after levels, photo record and the 20-year product and workmanship warranty certificate — everything the asset register, insurer or auditor needs in one pack. If the foundation issue returns, so do we.
Commercial concrete slab relevelling and ground stabilisation for buildings that can't stop working.
A warehouse floor that's dropped at one end. A footpath with a lip the council keeps getting calls about. A loading dock slab that's sunk away from the building. The concrete is usually fine — the ground beneath it has moved.
The conventional fix is to cut the slab out and pour it again. Weeks of closure, heavy plant on site, and a surface nobody can trade on while it cures. For most commercial slabs, that's the wrong job.
Concrete relevelling with GeoPoly™ resin injection works through coin-sized holes. The resin fills the voids, compacts the ground and lifts the slab back to level — laser-monitored, to the millimetre. The surface is trafficable within minutes. Tenants, staff and the public stay where they are.
The same ground stabilisation sits under underpinning for subsiding buildings, and structural crack repair with HelicalBar™ reconnects the masonry above it. A structural engineer designs the repair. Licensed builders carry it out. The products are made in Buildfix's own facility. One company, one fixed price, one 20-year warranty.
What we repair
Six structural repair disciplines. One company.
Every one designed by a structural engineer and carried out by the same crew.
Concrete slab relevelling
Warehouse floors, carparks, loading docks, footpaths and aprons lifted back to level without cutting out and repouring. Trafficable the same day.
How it worksGeoPoly™Ground stabilisation and underpinning
Resin injected beneath the footings compacts the ground and stops the movement, then lifts and levels the structure. Days, not months.
How it worksHelicalBar™Structural crack repair
Stainless steel reinforcement bonded into the mortar joints reconnects cracked masonry as one structural unit. No walls knocked down, no scaffolding.
How it worksGeoPoly™Floor pier stabilisation
Sinking brick or concrete piers re-supported by injecting beneath the pad footing. Done from the subfloor — tenants stay put.
How it worksDampBlock™Damp proofing
DampBlock™ injection creates a permanent damp-proof course inside the wall. Stops rising damp at the source without cutting the masonry.
How it worksHelicalBar™Remedial wall ties
Failed cavity ties replaced with high-tensile stainless steel. Reconnects the outer leaf to the inner structure from the outside.
How it worksProof, not promises
Three commercial lifts, start to finish.

Made by Buildfix
The products on your site are made by the company installing them.
In 2019 Buildfix acquired its own manufacturing facility in Seven Hills, Sydney. GeoPoly™ resins, HelicalBar™ reinforcement and DampBlock™ damp-proofing are formulated and made there, to Buildfix specification, for Australian soils and masonry.
Most structural repair contractors buy a resin off the shelf and rebrand it. Buildfix is the only company in Australia that owns, formulates and manufactures its own.
Batch control.
Every batch is made to the same specification. No substitutions, no supply-chain surprises mid-job.
Fixed price holds.
Material volumes are known before the crew arrives, so the quoted price is the invoiced price.
Warranty from the maker.
The 20-year warranty is backed by the company that made the product and did the work — not a supplier who may not exist in five years.

Why asset owners hand the job to one company
The same standard on a council footpath as on a 16-hectare parkland.
Structural engineers design the repair. Licensed builders carry it out. The products come from Buildfix’s own factory. If anything comes up in the next 20 years, there is one number to call.
