When concrete saw cutting, aim to cut to a depth of one quarter to even one-third of the concrete slab thickness. When cutting concrete with a circular saw you don’t want to cut too shallow or else risk random cracking.
How Deep to Saw Cut Concrete?
Saw cutting concrete is a process used to create precise cuts in concrete slabs of any depth and width. It is often used to create expansion joints in order to control cracking in concrete slabs due to thermal expansion or contraction. It is also used to create drainage channels, control joints, and to cut out sections of concrete for repair work or new installations.
The depth of cut required depends on the project requirements and the type of concrete being cut. Generally, the deeper the saw cut, the more likely it is to control cracking in the concrete. If the saw cut is too shallow, the concrete may still crack due to thermal expansion or contraction.
For most projects, the depth of the saw cut should be at least 1/4 inch deep. In some cases, deeper cuts may be required. For example, if the concrete slab is going to be subjected to extreme temperatures or is going to support heavy loads, then a deeper saw cut may be necessary.
When saw cutting concrete, it is important to use the correct type of saw. Different saws are designed to cut through different materials. For example, a masonry saw is designed to cut brick and stone, while a concrete saw is designed to cut through concrete.
