Drainage and plumbing runs
Cuts through ground slabs so new waste and stormwater lines can be dug in under bathrooms, laundries and kitchens.

Floor sawing
Sydney
Floor sawing — also called slab sawing — cuts straight, controlled-depth lines through a concrete floor, slab, driveway or path. We cut for new drainage runs, openings, lift pits and expansion joints, in occupied homes and tight spaces as well as open sites.
What it covers
What is floor sawing used for?
Floor sawing cuts a concrete slab along a marked line to a set depth so a section can be lifted out or a joint formed. Typical jobs are bathroom, laundry and kitchen drainage, openings in slabs, lift pits, expansion and control joints, and cuts through tiled or paved floors and the slab beneath.
Openings in slabs
Square-cut openings for stairs, hatches and services, set out from your marks or drawings.
Lift pits and sumps
Controlled cuts for lift pits, sumps and drainage pits going into existing slabs.
Expansion and control joints
Sawn joints in slabs and pavements so the concrete cracks where it should.
Tiled and paved floors
Cutting through tiles or pavers and the slab beneath in one clean line.
Driveways and paths
Saw cuts through driveways and paths for new crossings, drainage and pit connections.

On the job
What it looks like
How the job runs
How does a floor sawing job run?
-
01
Check what is in the slab
Before a cut we check what is in and under the slab: services, conduit, reinforcement and post-tensioning. A cut in the wrong place cannot be uncut.
-
02
Mark it, then cut it
Every line gets marked and checked against your drawings or your marks, and the depth is agreed before the saw starts.
-
03
Wet or dry
Outside, or on deep cuts, we cut wet and manage the slurry. Inside an occupied building we keep dust and water under control. Which one suits gets decided on site.
-
04
Clean handover
The offcut comes out, the area gets cleaned up, and the next trade can start.
What it costs
What does floor sawing cost in Sydney?
Floor sawing is priced on the cut, not the hour: the length and depth of each cut, how heavily the slab is reinforced, whether there are tiles or pavers on top, and how hard the spot is to get gear to. A ground-floor slab you can drive to is cheaper than the same cut up a stairwell. Small jobs usually carry a minimum call-out, so it is worth bundling everything you need cut into one visit.

Questions
Floor sawing questions
Can you cut a slab inside a house?
Yes. Bathrooms, laundries, stairwells and tight spots between walls are normal floor sawing jobs. We control the slurry or dust and clean up behind us.
Do you cut reinforced slabs?
Yes. Diamond blades go through rebar and mesh. Heavy reinforcement slows a cut down, so mention it when you call and the quote will be right first time.
Can you cut through tiles and the slab together?
Yes. We cut through the tiles and the slab beneath in one line, so the edge is clean for the plumber or the tiler who follows.
What about post-tensioned slabs?
They need to be confirmed before any cut. Tell us what you know about the slab and the building. If it may be post-tensioned, the cut lines have to be checked first. We will not guess.
