Saw Cut Concrete Joints
Saw-cut concrete joints are intentional cuts made into a concrete slab after it has been placed and begun to harden. Their primary purpose is to control where the concrete cracks as it shrinks during curing.
Control Cracking
- Concrete naturally shrinks as it dries and cures.
- Without joints, shrinkage can cause random, unsightly cracks.
- Saw cuts create a weakened plane so cracks form beneath the joint instead of elsewhere.
Reduces Maintenance
- Controlled cracking helps preserve the slab's structural integrity.
- Properly placed joints can reduce future repair costs.
Accommodate movement
- Concrete expands and contracts with changes in temperature and moisture.
- Joints provide relief for these movements, helping prevent damage.
Improve Appearance
- Cracks that occur at saw-cut joints are much less noticeable than random cracks across the slab.
- This gives driveways, sidewalks, patios, and floors a cleaner, more professional look.
Typical applications
Saw-cut joints are commonly used in:
Driveways
Garage Floors
Sidewalks
Parking Lots
Warehouse and industrial floors
Concrete Pavements
