I know that ACI 318 states in section 7.7.1 clear cover for "concrete cast against and permanently exposed to earth" clear cover is 3 inches. Are there any specific requirements or recommendations for a slab and grade beam system that will be cast against the earth, but the soil should settle below? Furthermore, if the slab system is placed on stone and a vapor barrier, does the 3" cover still apply? I am currently trying to maintain the 3" cover, however my reinforcement is getting heavy. Any suggestions on how I can handle this issue or references I may use will be greatly appreciated. Thank you.
