The Vevor pool liner pad is designed to protect above ground pool liners from punctures caused by rocks, roots, glass, and other sharp objects. Made from extra-thick geotextile fabric, it adds cushioning underfoot while helping block weeds and reduce contamination beneath the liner. Its durable recycled material construction supports long-term use and helps extend liner life. The pad can also be trimmed for fitment and installs quickly for a cleaner, more secure pool base.
