Concrete sawing, also called slab or flat sawing, is the work most of our jobs start with. A walk-behind floor saw fitted with a diamond blade runs along a marked line and cuts down through the slab, leaving a clean, straight edge that is ready for the next trade. It is faster and far quieter than breaking out with a jackhammer, and it doesn't shatter the concrete you are keeping.
Cutaway Concrete Cutting has been cutting slabs across Sydney since 2003. We cut trenches for plumbers and electricians, openings for stairs and lift pits, saw lines for slab removal and control joints in new pours. On residential renovations, fit-outs, warehouses and civil sites, the brief is the same: cut exactly where it's marked, to the depth you need, and leave the site clean.
Every job is wet-cut. Water on the blade suppresses dust, including respirable crystalline silica, and keeps the blade cool so the cut stays true. Slurry is contained and cleaned up as we go, which matters a great deal on internal jobs and occupied buildings.
Trenches for plumbing and services
The most common slab cut in Sydney is the service trench: two parallel saw cuts through the slab so a section can be broken out for new drainage, water or electrical runs. Bathroom and kitchen renovations, shop fit-outs and warehouse upgrades all need them.
We cut both sides of the trench to depth, so the concrete between breaks out cleanly and the remaining slab edge stays sharp and sound. That makes reinstatement simpler and gives a neater finish when the trench is filled.
Slab openings, removal and control joints
For stair voids, lift pits, skylights and new penetrations, we saw the perimeter of the opening so the section can be lifted out in pieces. Where a slab is coming out entirely, we cut it into manageable sections for removal by machine or by hand.
On new concrete we cut control joints at the right time after the pour, to the spacing and depth set by your engineer, so cracking happens where it is meant to and not across the middle of a panel.
