I had a concrete slab poured in s. fl yesterday 7/29 by a contractor. It is connecting to an existing concrete drive and sidewalk. I noticed visible trowel marks along the edges and some little holes and visible rocks in some places (edges)... It was supposed to have a broom finish but the contractor said they couldn't do it because too many rocks came to the surface when they tried, thus the trowel marks. He said he would buff the surface to get rid of the trowel marks but now doesn't want to bother as he feels it looks "good" :confused: Also, you can visibly see the edge of the sidewalk about 1/2 inch or less and drive it connects to.. I thought it would be level with these surfaces... now I am afraid water will just collect there? The contractor doesn't see this as a problem. Of course, I am no expert, but I think this is his error... My question is are these issues definitely installer error that would justify renegotiating price? And are these indications there may be future issues with the concrete?
