Chatted with a concrete guy named Gary who totally changed my pour strategy
I was talking to Gary over at Sherwood Park Concrete last week about a small patio slab I messed up. He mentioned that he always wets the subgrade the night before a pour, even in summer, to stop the base from sucking moisture out too fast. I never thought about that before, but it makes sense with our clay soil here. Has anyone else tried pre-wetting their base or do you just go for it dry?
