slab and wall joints in concrete tank
in a liquid-filled tank, must construction joints in the wall align with the construction joints in the slab? these are construction joints, not contraction joints--i.e., continuous reinforcement.
specifically, this is for a circular tank, and according to the specs, the slab will be placed in six pie-shaped segments, so that the joints align with the joints in the walls, which are limited to 60 feet placement lengths. why does it matter whether the joints align?
aesthetics only.
i would recommend lining them up. if you get a crack at the joint it might continue into the adjoining wall or slab and leak. it won't be a lot of leakage, and it will close up, but it will still be there.
i sometimes have more joints in the walls than slab (usually twice as many), but i still try to match them up where i can.
