What concrete cutting covers

Concrete cutting is the sawing side of the book. Floor saws run long, straight, line-marked cuts through slabs — expansion joints, demolition lines, trench openings — to 530mm deep. Wall and track saws cut vertical, horizontal or overhead to 730mm for door openings, window apertures and stair removals. Wire saws handle what blades can't: mass concrete, awkward shapes and tight access on bridges, foundations and plinths, with no practical depth limit. Hand-held cut-off saws cover the quick patches, plumbing kerbs and brickwork where bigger gear can't reach.

Every method is diamond-bladed and water-managed — controlled, low-vibration cuts rather than percussive breaking, which is what keeps the surrounding structure sound and the rest of the building working while we cut.

Typical use cases

• Structural openings — door openings, window apertures and stair removals cut clean through reinforced walls and slabs.
• M&E openings — rectangular slab and wall openings where a core barrel is the wrong shape for the service run.
• Trench openings and slab penetrations — floor-sawn trenches for drainage and services through ground-bearing slabs.
• Expansion joints and demolition lines — long, straight, line-marked cuts to depth.
• Controlled concrete removal — sequenced cuts so sections come out to plan, not to chance. Kerb removal included.
• Mass concrete — wire-sawn cuts through bridges, foundations and plinths where blade depth runs out.

Who it helps

Main contractors cutting structural openings around a live programme. Demolition contractors who need sequenced, controlled cuts rather than percussive breaking. M&E and fit-out teams with openings too big or too square for a core barrel. Facilities and estates teams altering occupied buildings where vibration, dust and noise have to be managed. Groundwork on trenches, joints and kerb lines where the cut has to be straight and to depth.

What to send for a fast quote

• Site postcode and access route — can a floor saw get to the slab?
• Drawing or sketch of the cut lines with dimensions.
• Slab or wall thickness, and reinforcement notes if known.
• What's below or behind the cut — services, live areas, finishes.
• Working hours, deadline or permit window.
• Photos — even a phone snap of the area helps.

Half of that is enough to come back with a price; the rest tightens it up. Full quote checklist here.

Safety, dust and clean-work notes

Cuts run wet — water cools the blade, keeps respirable silica out of the air and captures the slurry at source. Slurry is contained with squeegees, sumps or vacuum extraction depending on access, then removed or bagged out as agreed up front, and the slab is handed back clean. Scanning happens before the saw is set on any slab where reinforcement, services or post-tension matter. RAMS, COSHH and any required permits are issued before the crew mobilises.
