gopher13 said:The case for continuing the reinforcing through the sawcut joint: If the slab thickness and reinforcing remains the same throughout the area and a sawcut is made, that section through the slab where the sawcut is would now be the weakest point, right? So the crack should form at the sawcut and not a some other random location where there is no sawcut.
(slab thickness "X" with reinforcing "Y") > (slab thickness "X - sawcut depth" with reinforcing "Y")
