How long to let concrete cure.... I've poured my footing, and a small pier block on top of it. The footing is 2'x2'x12 and the pier block on top of it is 10 x 10 x 10.he pier block should be filled with concrete if you want it to carry any sort of load. I would use a min 1/4 inch metal plate between the Girder and the filled block. Concrete= Keep it wet, 28 days if you can afford to wait that long.
