expansion joint in concrete
expansion joint in concrete
(OP)
I am designing a 140 foot long concrete screen wall that is only about 4 feet above ground and then another 4 feet below ground (below frost). Do I need to put any vertical expansion joints in this wall? (Meaning a joint through the thickness of the wall) Maybe every 40 feet? Is this a bit excessive, or can I just do control joints to try to control cracking?
