Learn About Curing Concrete with Water and Membranes
Wet Covering: Curing concrete with wet covering is done after the concrete has hardened sufficiently and the water covering will not damage concrete’s surface. A covering is usually sand, burlap, canvas or straw that is kept continuously damp during the curing process.
Wet Curing and Drying Time
With wet curing, the added moisture serves to stabilize the excess loss of evaporated water in concrete. However, surface moisture interacts with slab water vapor that migrates from the bottom to the top of the slab. Moisture in the drying process must leave the slab by evaporating from the slab surface. So while wet curing may address …
