My new guy wanted to use fast concrete in the mud. I said no.
We were setting posts for a vinyl fence behind a bakery. The soil was pure muck after a downpour. My apprentice, keen to get home, cracked open a bag of rapid-set concrete. I had to stop him right there. I told him that stuff needs dry conditions to work right. In soup like this, it just turns to mush and won't hold. We dug out some of the wet dirt, used regular mix, and packed it slow. The boss checked it later and said we did the right thing. How do you folks deal with hurry-up moments that could wreck the job?
