Concrete: cure time question


I'm pouring a 3000 psi concrete footer for a block wall.

1) how long should the footer cure before building an 8 course block wall on top? (I will be drilling holes in the footer to epoxy vertical rebar for the block.

Put the rebar in when you pour the footing.

X2, install the rebar during the pour - that epoxy is expensive

Couple days to cure.

I have seen the rebar dowels pushed in or set when the strip footings are poured. Block (the first course or two are sometimes laid laid late the day of the pour since the lines and batter boards are still in place. It is also done to proect from an overnight rain that could cover the footings in the excavation with mud and water.It is much easier to make the final squaring of the foundation if the first course or so are in place, but adjustments are usually not necessary if the footings were laid out from a proper reference.

A week should be fine but put your steel in BEFORE pouring

Place the steel before pouring like suggested. And lay the block the next day. Or if you pour early in the day you can lay a few courses that afternoon like dick said.
