I am not trying to start a war here,,, I just think that the biggest problem is that most of you guys never stamped concrete, and didn't do alot of reading about it Like olderthandirt said, the prep is important. I am not knocking pavers, as I love the look of them and install them but stamped concrete (done right) will last a lifetime. As far as the freeze/thaw, if you have a good base of gravel that will keep water from laying, the whole problem of frost is eliminated. I live in a cold climate (northern Pa) and have been installing concrete for 15 years and yet to have a major problem. The products that are out there as far as sealers, confilm, pigments pretty much assure the concrete will last a long, long time. Pavers are by far loosing the race in my area, I rip out at least 2-3 thousand square feet every year to replace with stamped or stained concrete. Not saying stamped is better than pavers, but this is what the market is calling for.
