What is Soff-Cut?
Soff-Cut is a system developed for ultra-early sawing of contraction joints after pouring concrete slabs. It’s the optimal solution for minimising the risk of random cracking, which is one of the most costly and aggravating problems faced when laying a large concrete slab.
How deep does a soft cut saw cut?
The Soff-Cut® system is the optimal way to control random cracking, by cutting control joints as part of the finishing process, within the green zone. With Ultra Early Entry™ cutting you can control cracking in slabs up to 9 inches thick, with only a 1-inch minimum depth.
How deep should saw cuts be in concrete?
A good rule of thumb is to cut the joints one-quarter to one-third the slab thickness. 1 For a 6-inch-thick slab, that means cutting 1.5 to 2 inches deep. Ensure that the saw cut depth meets the structural engineering specifications.
How do I keep my concrete slab from cracking?
If you’re having new concrete poured consider the following ways to prevent cracking:
- Start with a sound subgrade. Make sure the subgrade is compacted.
- Modify the concrete mix. Use a low water-to-cement ratio.
- Install joints. Be active in deciding where control joints will be placed.
- Properly cure the concrete.
