Had a concrete pour go sideways on a garage slab last month, still not sure what I should've done different
I'm over in Lethbridge and took on a small garage slab for a buddy's place. About 20 yards. Everything looked good, forms were solid, rebar in place. But then halfway through the pour, the ready mix truck shows up with the wrong slump. Like way too wet. I told the driver I ordered 4 inch slump and he just shrugged said that's what they sent. I was stuck because it was a Friday afternoon and I couldn't get another truck for hours. So I poured it anyway, tried to work with it, and now I've got some cracking along the control joints that I'm not happy about. Customer didn't complain yet but I know it's not my best work. Should I have just sent the truck back and taken the loss for the pour? How do you guys handle it when the batch is wrong and you're already on site?
