Quality Product
Easy to install and the rubber works best between the concrete foundation and new paver patio installation.

Size does matter
I am so glad I purchased this trial pack. Had I not, I would have ordered and returned 250โ of flexible rubber strips because they would not have been the correct size. I measured several times, but until you have the samples to place where you want them, you wonโt know for sure the size you actually need. Worth the price!

Easy to install - looks great
I replaced the old cracked expansion strips in my 1970s pool decking with this and it worked GREAT. I just removed the old strips, used some cement filler to fill in the extra space under the new strips and it also helped to sort of "glue" them in. Perfect fit and very easy to install. Used scissors to cut to size and in some cases trim the bottom if necessary for a Perfect fit. This is VERY DIY friendly. I did my whole pool deck in about an hour (15 expansion strips).
