What happens if you don't cut concrete?

Cutting too early can mark the pavement surface as well as cause joint raveling. Late sawing can result in random concrete cracks.

How do you score and break concrete?

Use a standard circular saw, equipped with a corundum or diamond blade, for small tasks. For slabs, it’s best to cut through the top inch, then use a sledgehammer to break off the rest. The jagged edge left below the cutting line provides a good rough edge for the new concrete to bond to.

When can you cut lines in concrete?

Sawing too late can result in uncontrolled cracking as the concrete contracts during curing. Saw cutting can start anywhere from three to six hours after the concrete is poured, depending on the weather conditions. The best way to determine whether the slab is ready is to make trial cuts to check for raveling.

Does rebar prevent cracking concrete?

Steel reinforcing bars and welded wire reinforcement will not prevent cracking. Reinforcement is basically dormant until the concrete cracks. After cracking, it becomes active and controls crack widths by restricting crack growth.
