Concrete slab cutting is essential for creating utility trenches, expansion joints, staircase openings, and floor modification openings. Our diamond flat saws produce precise, clean cuts through floor slabs of any thickness — from 100mm domestic slabs to 500mm industrial floors — without vibration or impact damage to the structure below.
Diamond flat saws for floor slabs — trenches, expansion joints, staircase openings
What is slab cutting?
Slab cutting (floor sawing or flat sawing) uses a powerful walk-behind or ride-on diamond blade machine to cut horizontal cuts through concrete floor slabs, road surfaces, and ceilings. Diamond blade flat saws operate at high blade tip speeds and use water cooling for precise, straight cuts. Unlike jackhammers, flat saws produce clean, vertical cut faces that can be reopened cleanly if the trench needs to be accessed again later.
What is it used for?
- Plumbing and drainage trench openings in floor slabs
- Electrical conduit trench cutting
- Staircase opening creation in floor slabs
- Expansion joint cutting in industrial and commercial floors
- Utility access panel creation
- Road surface cutting for utility repairs
- Renovation access to basement services
- Swimming pool construction slab cuts
Our process.
Mark & Plan
Cut lines are marked on the floor and checked against structural drawings to avoid utility services and structural elements below.
Core Corners
For rectangular openings, we core drill the corners first to create clean turn points for the flat saw blade.
Flat Sawing
Diamond flat saw makes precise straight cuts at the specified depth. Water-cooled for dust control and blade longevity.
Break Out
Cut concrete sections are carefully broken out and removed. Edges are clean and ready for services installation.
Cleanup & Handover
Slurry and concrete debris removed. Trench or opening handed over clean for MEP contractor or other trades.

Why choose us for
slab cutting in Palakkad?
Common questions.
Can slab cutting damage the rebar in the slab?
The cut will go through rebar if it is in the cut path — this is intended for openings. For trench cuts where you want to preserve the slab integrity, we check drawings and may mark around rebar locations. We always discuss the structural implications before cutting.
How deep can you cut in one pass?
Our standard flat saws cut up to 500mm depth. For deeper cuts, we make multiple passes or use wire sawing.
Can slab cutting be done indoors?
Yes. Wet cutting with vacuum slurry collection is clean enough for indoor work. We use industrial vacuums to capture slurry before it spreads.
