Concrete Floor Preparation in Sydney

Every floor prices differently, because the cost is driven by what's on the slab rather than by how big it is. A general grind to open up a slab for an epoxy system sits at one end; taking off glues, toppings or a failed coating sits at the other. Area, access, out-of-hours work and the amount of edge and detail work all move the number, and Sydney jobs carry access costs a ground-floor warehouse never does — a booked dock, a single goods lift, a night shift. We price the actual floor rather than work from a rate card, and the site visit costs nothing — the quickest way to get a real figure is to send us the details — the floor area, what's down now and what's going down afterwards — and we'll come back with a proper price.

It depends on the slab and the specification, not the size of the floor. Shot blasting is fast across open floor plate and gives a consistent profile, which suits most resin systems. Grinding offers more control, handles coatings blasting won't shift cleanly and takes high spots down. On occupied Sydney sites the decision is often made for us — grinding under vacuum extraction is the only workable option where an adjoining tenancy stays open. We walk the floor before quoting, so the method is settled before anyone mobilises.

Close to it, though not literally. The shot and debris are recovered under a contained hood as the machine runs, which keeps dust down to the point where blasting is viable inside occupied buildings. There's still some, so we contain the work area and run extraction alongside it. In a Sydney CBD tower or a strata building with tenants either side, that containment is usually what building management wants to see before we are allowed onto the floor.

Yes, and in Sydney most of it does. Retail tenancies, hospital and aged care floors, food production lines and CBD office levels all have to be handed over empty, and building management commonly restricts noisy work to nights and weekends in any case. We plan the shifts around the building's access hours and the date the floor has to be back in use.

A day is the useful unit. An open 500 m² warehouse floor at Eastern Creek or Wetherill Park will blast in a day; the same area of tiled retail with adhesive residue, columns and edge work can run to three. Access moves the number more than area does, and in Sydney it moves it a long way — a ground-floor roller door out west is a different job to a high-rise CBD tenancy with one goods lift and a dock booked in two-hour slots. We give you a day count with the quote rather than a range.
