SANG DIAMOND TOOLS Soff-Cut diamond blades is specially designed for efficient sawing of contraction joints in newly poured concrete slabs. This method reduces the risk of random cracks in the cured concrete.
Early Entry: This is the critical technique. Instead of waiting 4-12 hours (or overnight) for the concrete to gain enough strength for a conventional "wet cut," early-entry sawing is done 1 to 4 hours after finishing, while the concrete is still quite green.
Common Diameters: 6” , 9” , 12", 14"
Application: Creating control joints in: Industrial floors, Warehouse slabs, Driveways, Sidewalks
Patios
Advantage: Dramatically reduces the risk of random cracking that can happen before standard sawing.
How it works: A special saw uses a down-pressure kit (rolling weights) instead of the blade's own weight, preventing damage to the tender concrete surface.
Blades: These are not standard diamond blades. They are specifically engineered for the unique demands of early-entry sawing.
The combined properties of the saw and diamond blade enable you to cut the joints on the same day as the concrete is poured, without the concrete chipping or spalling. This allows for a more efficient process “from pour to floor”.
Random cracking is the most costly and aggravating problem for concrete contractors. Using SANG Soff-Cut blades with your early entry saw is the safest way to ensure a productive workday with excellent results.
Prevents Random Cracking: Cuts joints before internal thermal and shrinkage stresses cause cracks.
Cleaner Joints: Produces sharp, clean edges with minimal raveling.
Operational Efficiency: Crews can saw and finish a slab in the same work cycle, no need for after-hours wet sawing.
Safer & Cleaner: No water slurry to clean up, reducing environmental and slip hazards.
Start sawing as soon as you’re sure the concrete will support the weight of the saw and operator without marking or damaging the concrete.
Determine the layout of the contraction joints in advance. Ensure straight cuts by drawing guidelines on the surface to follow.
