I’m pouring a small slab for some pool equipment. It will be 4’x8’x3.5”. I expect little to no foot traffic, just a heater, pump, and chlorinator. (Mabye foot traffic just when adding tablets)
Do I need a control joint in the middle? Or do you think my slab is small enough to get away with nothing.
(I have minimal concrete experience in slabs... just things like post holes and filling blocks)
