Spotted a weird pour at a gas station in Tulsa last week
The concrete pad around the pumps had this huge crack line that zigzagged through the whole slab, no control joints anywhere. They must have poured it all in one go without any planning, has anyone else seen a mess like that at a commercial site?

You seen the control joints yet on that slab? Odds are they forgot to cut them in after the pour, or the crew just skipped it entirely. Without those joints, the concrete has nowhere to relieve stress so it cracks wherever it wants. That zigzag pattern tells me the ground probably shifted a bit or the slab was poured on a hot day and didn't get proper curing. Best fix now is to saw cut some straight lines across the slab to guide future cracking, or you'll end up with chunks breaking loose near the pumps. That's a trip hazard waiting to happen, especially if a customer trips and sues the station owner.

Yeah I actually read somewhere that if you pour concrete on a really hot day and don't mist it down regular, the top dries way too fast and that's what makes those zigzag cracks. Sounds like that could be what happened here. Sucks because now they gotta cut joints and hope it doesn't keep splitting.
