The pool walls are constructed with duraplus, a material reinforced with a polyester mesh core and two layers of high gauge pvc for superior strength and durability. Framelink system - custom-molded t-connectors prevent metal-on-metal corrosion, realistic prismatic stone printing provides the pool with a beautiful print that adds texture and a rich blue color to the inner liner. Easy 20-minute setup, heavy-duty pvc and polyester 3-ply side walls provide additional support.
