Concrete Joint Guides
Short, practical answers to the jointing questions that come up on every slab — spacing, depth, and timing.
Control joints
Concrete Control Joint Spacing Guide
How far apart to cut control joints in a concrete slab: the 24 to 36 times thickness rule, spacing by slab thickness, and how to keep panels close to square.
How Deep Should Concrete Control Joints Be?
Control joint depth for concrete slabs: the one-quarter thickness rule, depth by slab thickness, and why shallow cuts lead to random cracking.
When Should Concrete Be Saw Cut?
Timing concrete saw cuts: why there is no single number of hours, the signs a slab is ready, and how weather and mix change the cutting window.
