That's damn cool! We made concrete block benches out of it and it's stable and even heavy rains didn't bother us. We tried to find it in several stores and couldn't, so we bought another brand and it didn't last AT ALL! With this one tube, 5 sets of two cinder blocks could be glued together. Be sure to wait the required amount of time or more before moving and make sure you hit the cracks. If the blocks don't sit flush on top of each other, this will help it connect even better. Work quickly when you start because it will get sticky quickly and it will be difficult to spread once you do it with it. This review was NOT given in exchange for a free product. I would buy it again and again, in fact I did!
