This really is one good tarp. This Blue polyethylene tarp is a full finished size opposed to other "cut size" tarps. There has been no rain fall to weigh it down and only a slight breeze at best. I bought this tarp to put under my Intex pool as a ground cover. It is doing the job, but since it's much larger than I needed, I had to fold the ends under and secure with tent stakes, which I had to go out and buy at a brick and mortar store. The material seems kind of thin, but again, it serves it's purpose as the ground cover for the Easy Set pool.
