What is concrete cutting?
Concrete cutting is making an opening, or taking a section out, of an existing concrete floor, wall or slab. We do it with diamond sawing and diamond drilling, often together.
It's used a lot for doorways, stairs and lift shafts, and for routes for pipes and ductwork. The edges come out clean, so the rest of the structure stays as it was.
What it's used for
- Doorways and window openings
- Stair and lift-shaft openings
- Routes for services and ductwork
- Taking out sections of slab or wall
- Alterations and refurbishment
How a job goes
- We agree the size and position of the opening with you.
- The opening is marked out, and corners are core drilled where needed.
- The lines are diamond sawn.
- The section is lifted out, or cut into smaller pieces first if it's heavy.
Things to know before you book
Anything structural needs a structural engineer. They may specify temporary support (propping) while the opening is made, and a lintel or other support after.
Check what's inside or behind the concrete before cutting: pipes, cables and reinforcement. Services should be located and isolated first.
Plan how the cut-out sections will be moved and taken away. Concrete is heavy.

Concrete Cutting questions
What's the difference between concrete cutting and concrete sawing?
Sawing is the method. Cutting is the job of making an opening or removing a section, usually done with sawing and drilling together.
Can you cut openings in existing buildings?
Yes. That's most of what concrete cutting is used for.
Do I need an engineer?
For anything structural, yes. A structural engineer should approve it first.
Do I need permission to cut an opening?
It depends on the building and the work. Structural changes usually need a structural engineer, and may need building regulations approval. Check with your local building control.
How is the cut-out piece removed?
Smaller sections can be lifted out. Larger ones are usually cut into smaller pieces first so they can be handled safely.
How long does it take?
It depends on the size of the opening, the thickness and the access. Send us the details and we'll give you an idea.
