Re: Placing concrete walls on footings before 7 days

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Did you have 7 days listed in your concrete specifications? Or just a reference to ACI 301, etc.?

I have been asked about the need to wait 7 days before placing a concrete wall on a new footing.  Is this an enforcable requirement referenced by the code?  Or this only a guide and a "proceed at your own risk" situation if placing the wall before receiving 7-day breaks on the footing?
And is there a similar requirement that forms cannot be erected on a footing until 3 days after footing placement?
