Not good...a few years ago, we had Chandler come out to pour concrete for a stone driveway that we were putting in ourselves. It was the driver's first day. He was late, the concrete was rock hard; in fact, so hard that I had to climb up to the top of the chute and shovel down the concrete while my husband squirted water in it to keep it wet. If we had not taken off work to do this job, we would have refused it. Once down, we had to use our TILLER to break it up, as it was dry already. As it is, our walkway stones are all now cracking after this pathetic load of concrete that we paid for was so substandard that the foundation was terrible. For our back walkway, perfection. Stones are solid and non-cracking, etc., after using a different company. I only wish I had called and demanded every penny back; but did not know the results of such bad service and product. Our walkway will cost thousands to replace, after only several years...
