Werribee is the oldest part of Wyndham, and it shows up in the slabs. Most of what we quote here was poured between the 1960s and the early 1990s — which changes what has to happen before any coating goes down.
Floor shown is a visualisation — stock reference photography, not a completed Ironclad job.
Werribee is not simply basalt country, which surprises people who assume the whole of Melbourne's west is one thing. Geotechnical work through the Werribee growth area describes a Quaternary veneer of delta silts and clays — several metres of it in places — sitting over the Newer Volcanics basalt at depth. The clay at the surface is reactive either way: assessments in the area have recorded characteristic surface movements in the order of 40 to 70 millimetres, which is a slab that lives with the seasons. Your own lot's classification comes from a soil test on that lot, not from the suburb.
For a coating, though, movement isn't the first question. Age is. An under-slab vapour barrier only became a prescriptive national requirement with the 1996 Building Code, which Victoria adopted in August 1997; the performance-based requirement before it dated from 1988. A good share of Werribee's housing predates both. Where there is no intact membrane, moisture travels up through the slab, and sealing it in means hydrostatic pressure pushes the coating back off. That is why we moisture test before a drop goes down, and why the test genuinely changes the answer in older Werribee more often than it does out in the new estates.
One more local factor worth knowing: assessments around Werribee have pointed at drainage and tree proximity — not just soil type — as what actually drives movement under a footing. Flat ground that sheds water slowly, and a mature tree close to the slab, matter more than the label on a soil report.
The other Werribee constant is old paint. A lot of these garages got a tin of hardware-store floor paint at some point in the eighties or nineties. It is almost always lifting now, usually first in the arc where the car turns. It doesn't get coated over — it gets ground off, back to bare, open concrete.
Inter-war through to the 1990s, plus newer infill such as the Riverwalk estate on former treatment-plant land.
Single lock-up around 18–20 m², or an older double nearer 32–34 m² — noticeably tighter than a modern 36 m² double.
Lifting floor paint, oil staining, and a slab that needs a real moisture reading before anyone promises anything.
Same four stages on every job in Werribee, residential or commercial. No shortcuts, because we're the ones carrying the guarantee.
Diamond-ground back to bare, open concrete. Not acid-etched, not rolled over. Dust-extracted, so the garage stays clean.
Moisture tested before a drop goes down. Cracks and joints are cut out and filled so they don't telegraph through the finish.
Pigmented base coat, then decorative flake broadcast to refusal for full coverage, grip and depth. Your colour, chosen before we arrive.
Clear coat over the top, edges cut in sharp, site cleaned. You get the guarantee in writing before we leave.
One day on site. Walk on it after 24 hours, car back on it at 48. Gear moved and put back — you don't lift a thing. Written guarantee against lifting, and it transfers if you sell.
Werribee is a straightforward run for us, and getting a grinder onto a suburban driveway here is rarely the hard part of the job.
One Werribee-specific note: unlike the newer suburbs around it, Werribee has residential heritage overlays — the Carter Housing Estate and Carter Avenue precincts — and Wyndham's 2025 heritage review recommends more. Coating the inside of a garage floor is not an external alteration, so it is not normally a planning matter. If your property is in an overlay and you are unsure, check with Wyndham City before booking.
Access is usually easy: wide streets, room to park the truck, and driveways that take a vehicle-mounted dust extractor without blocking the road. The one thing worth checking before the day is power. Older Werribee garages sometimes have a single 10-amp outlet on a shared circuit, which a planetary grinder and a vacuum will trip. Tell us at quote stage and we bring our own supply instead of finding out at 8am.
No — and nobody honest will. A coating is only ever as sound as what it is stuck to, so if the old paint is letting go, anything laid over it lets go with it. We grind the paint off and take the slab back to bare, open concrete. That is what the written guarantee against lifting is written against.
More often than newer ones, yes. An under-slab vapour barrier only became a prescriptive requirement here with the 1996 Building Code, adopted in Victoria in August 1997, so plenty of older Werribee slabs were poured without an intact one. We moisture test every slab before coating, and if the reading is high we tell you what it means rather than coating over it and hoping.
Yes. A single lock-up is comfortably one day on site. You walk on it 24 hours after we finish and the car goes back on it at 48. We move your gear and put it back, so you don't have to empty the garage the night before.
