Hey All Need you heads! please. Im creating a floating concrete from steel deck for my basement. The deck is sandwiched between steels. the finished level is at the steel top plate. I will be sloping the deck one way to help with water drainage. Question, whats the minimum screed height when going over the steel top plate, as i suppose if its too thin the screed will crack and cause my slabs to move over time. As i suppose there might be some Buoyancy from the steels as well. Thanks Again
