Old timer told me to wet the subgrade before pouring. I thought he was crazy.
Guy named Hank, been pouring since the 70s, told me to hose down the dirt before my slab pour on a hot day in Phoenix. I figured it would just turn into mud. Did it anyway because he was buying lunch. That slab didn't crack a week later while my other dry-pour jobs looked like a spiderweb. Has anyone else tried this trick, or am I just late to the party?
