Pouring Walls on 3 Months Old Footing

Hello,

a question on the concrete experts here.
We did footings in December and could not continue due the weather.
We are now starting with the concrete walls and they will be poured end of March.
Can we just pour on top of the footings or is there anything to watch out for? Any preparation?

Is there a keyway in the footing? If not you should epoxy rebar into it vertically. The footing should be clean before you pour.

Yes, there are #5 rebar in. I am just concerned that the fresh concrete will not bond with the footing concrete.

The rebar helps to hold the foundation wall in place. The footer's main purpose is to stabilize the foundation wall so it won't sink. As long as the footer is relatively clean you should be fine.

Once you let one pour cure it really doesn't matter how long until the second as you are going to have a cold joint between the two. That's why the keyway or rebar pins to tie the two pours together is so important.
