Crete it Cutting & Core Drilling

DO NOT USE CRETE IT. OK so first initial visit was good, they seemed to know their stuff. I am very unsatisfied with the concreting, they laid a 3x3 slab for a shed and it isn't even, so the shed doesn't even sit flat also it is barely 3x3 so the shed has to sit on the very edge. Now to the worse part, we had a slab laid to have a patio put on, in one corner where they were supposed to dig out (we did pay for them to dig out) they didn't dig out enough so now its like we have a ramp in the corner of our patio. Exposed aggregate is very uneven, some spots are a lot more exposed than other areas also they showed us the rock to match into our other area and the end result does not match at all. Finally we now have cracking in the concrete. Again DO NOT USE CRETE IT
