The Vevor pool liner pad is designed to protect above-ground pool liners from punctures caused by rocks, roots, glass, and other sharp objects. Its extra-thick geotextile fabric adds cushioning underfoot while helping block weeds and reduce water contamination. The round 27' design fits compatible above-ground pools and can be trimmed for installation as needed. Made from durable recyclable material, it is built for long-lasting seasonal use. This underlayment helps extend liner life while supporting a cleaner and more comfortable pool setup.
