True or False: Edging and jointing is not required on most floors and should not be done unless specified.

• A. True
• B. False
• C. Not enough information
• D. Sometimes required

Answer: (A)

Edging and jointing are practices used to protect edges and control where cracks form in a slab, and their use is driven by project specifications. If the contract drawings or specifications don’t require edging or control joints, they aren’t automatically done on every floor. That’s why the statement is true: you follow what the project specifies, and edging or jointing is not mandated for every job unless the plans call for it. In larger slabs, though, crack control joints are commonly part of the design, so they’ll be specified there rather than applied by default.
