I live in PA, and in the summer of 2001 I had a new driveway, steps, and sidewalks installed. After the first winter, the steps started to pit badly (many holes of concrete popped out). After the second winter, the driveway also became badly pitted (especially parts closest to road). (The concrete guy said he used a linseed sealer.) Before the second winter, I used a Thomson's concrete sealer hoping that the problem wouldn't get worse. But the same thing happened after the second winter. I would like to at least attempt to make the steps and sidewalks look better. The good news is - the layout of the driveway, steps and sidewalk is good. The design was good. There is no lifting of concrete (four large panels makeup the driveway) nor cracks - just pitting everywhere! Would an overlay product do any good, especially for the steps? IF so, how can I find a reputable concrete contractor to do an overlay? Is there a database of contractors for the Pittsburgh area?
