Answer 1

Answer:

Joint Depths

If weakened planes or thin slab sections other than the contraction joints exist, random cracking may occur. Rule #7: For tooled or grooved joints, depth of the contraction joint should be 1/4 of the slab thickness. For interior floors, specify a 1/8 in. edge radius for the top of the groove or joint.
