The pool next door was a diy project. He explained the process and showed me some of the left over pieces of fiberglass etc. I have seen this thing inside and out. Swimcraft out of Ft Wayne Indiana is a major manufacture of this type of pool wall. They are mostly done on commercial pools. I spoke with them today. They have what I want, but wont sell direct to me because I am not a dealer or installer. I have my mind set that I will not install a liner pool. Guess I will keep looking.
