The edges are sealed with the most advanced machinery and bonded with extreme pressure heat to ensure an enduring bond that will last you. Computerized cutting tables are used to eliminate human error. Tough & long lasting due to welded seams. This liner will work on all same-depth, above ground pools that are between 48" and 54” in wall length. Protected against chemicals and UV rays so your liner will last the hot summers and long, Canadian winters
