Track record
Poured, finished, still flat
Every claim on this site traces to a delivered project. Here’s the evidence base — what was specified, what was replaced, and what the slab did afterwards.
28
SteelX projects recorded with full specification detail
400 mm
thickest Liberty™ slab delivered — MacKellar Mining
580 m³
largest single-night pour, Murarrie heavy industrial footings
What SteelX replaced
Taken from the specifications as issued, against the designs they replaced.
Bundaberg Brewing Co.
290 mm slab, N16-200 bottom + N12-200 top
235 mm + 23 kg/m³ SteelX 5:25 + SL81
55 mm off the slab and the top mat deleted. No joints, no visible cracks. Built by Hutchinson Builders.
Sunshine Coast Recreation Centre
Post-tensioned slab on ground
150 mm Liberty™ Slab, SL92 + 18 kg/m³
Post-tensioning removed entirely. No joints and no visible cracks.
Mooloolaba basement
450 mm, N16-200 EW top and bottom
SL81 top and bottom + SteelX
Watertight by design — external membrane deleted.
Defence causeways, Tin Can Bay
200 mm, two layers SL82 mesh
170 mm + 12 kg/m³ SteelX 5:25
30 mm thinner, both mesh layers gone, concrete pump eliminated across 12 causeway slabs.
Rogers Cold Store
35 kg/m³ double hook-end steel fibre
18 kg/m³ SteelX 5:25 + SL81
Half the fibre dosage for a better outcome. Repeat projects in 2023 and 2025.
Culvert apron, Gympie
N12-150 each way
175 mm + 18 kg/m³ + SL82
Bar deleted, mesh retained. Faster placement on a restrained civil element.

6
Mesh free slabs
Mesh replaced outright on schools, hospitals, defence causeways and industrial pavements.
3
Reduced reinforcement
Mesh retained and bar deleted on restrained civil elements and heavy-traffic slabs.
7
Bar free footings
Strip footings, pad footings, pile caps and bored piers poured without cages.
2
Structural watertight
Basement and podium slabs where the membrane came off the job entirely.

Jobs that set the precedent
Post-tensioning replaced
Sunshine Coast Recreation Centre
A slab originally designed as post-tensioned, delivered as a 150 mm jointless Liberty™ Slab. No joints, no visible cracking.
Fully restrained and crack-free
Toowoomba North State School
A 29 m × 21 m topping slab fully restrained by its edge beam — the hardest case for shrinkage. The engineer reported not a single visible crack.
Jointless at −40°C
Narangba freezer slab
A 31 m × 17 m freezer slab with no joints and no visible cracks, where hygiene makes a joint a liability.
580 m³ in one night
Murarrie heavy industrial footings
Poured at 20 kg/m³, all pumped, with steel retained only at areas of peak stress.
