Re: concrete on standing water

Have him throw some dry Portland cement in the puddles in a layer 3/4" to 1" thick if he wants to pour over the water.  It will be at least as strong as the soil in bearing and won't adversely affect the concrete strength.

Can anyone comment on the appropriateness of placing concrete on saturated soil?  I have a contractor that is asking if he can pour his strip footings thru some 1? standing puddles.  Said he has done it plenty of times in the past?

TIA
