RE: Concrete Cure Time

[Subject Prev][Subject Next][Thread Prev][Thread Next]

That means they are placing after the initial setting time. Is that going to be a problem? But generally we don’t do that. You may check the concrete lab report for the particular pour.

Stick to your guns.  Otherwise, you may want to draft a letter to your client stating you will be held harmless for damage to the slab or floor finishes that (likely) would be caused by the early loading...  That can get really legal, really quickly...

Our residential clients have been pushing the time frame on when they can start running block after a slab pour.  Our standard has been 3 days.  However, some clients think this is too long, and we have recently found one placing block a mere 20hours after the pour…


So the questions has been brought up – what is the fastest time frame for block placement? Any code ref’s I can from here?
