Concrete Chainsawing Sydney
Concrete chainsawing is a concrete-cutting method that uses a diamond-tipped chain saw (similar in appearance to a timber chainsaw) to cut square corners, deep penetrations, and irregular openings in concrete and masonry.
How it works
Instead of a rotating blade, the saw uses a chain fitted with industrial diamond segments that runs around a guide bar.
As the chain rotates, the diamonds grind through:
- Concrete
- Reinforced concrete
- Brick
- Blockwork
- Stone
Common Uses
Door and Window Openings
A major advantage of chainsawing is the ability to create square corners without overcutting.
Service Penetrations
- Irregular-shaped openings
- Electrical and plumbing penetrations
- Ventilation openings
Structural Alterations
- Wall removals
- Access openings
- Renovation work
Bridge and Infrastructure Work
- Small structural modifications
- Areas where a wall saw cannot be mounted
Advantages
✅ Cuts square corners
✅ No overcutting required in many situations
✅ Can plunge cut directly into concrete
✅ Accesses tight spaces
✅ Cuts deeper than many handheld saws
Limitations
❌ Slower than wall sawing for large openings
❌ More chain wear when cutting heavy reinforcement
❌ Not ideal for very large structural removals
❌ More expensive consumables than standard blades

Example
Suppose a builder needs a 600 mm × 600 mm opening through a 200 mm reinforced concrete wall for a new electrical cabinet. A wall saw would leave overcuts at the corners unless core drilled first. A concrete chainsaw can cut directly into the wall and produce nearly square corners, reducing patching and giving a cleaner finished result.
For most concrete-cutting businesses, chainsawing is a specialty service that complements core drilling, wall sawing, wire sawing, and ring sawing rather than replacing them.
