Pool liner pad for 18ft round above ground pools adds a protective cushion under your liner to help prevent punctures from rocks, roots, and debris. Made from heavy-duty non-woven geotextile fabric, it supports a smoother pool floor while helping block weeds and reduce liner wear. Trim-to-fit installation works with many soft-sided and hard-sided round pools, helping you extend liner service life with less hassle.

Set up your pool with added confidence by placing this ground cloth underlayment between the soil and your liner. The dense recycled geotextile construction is designed for season-after-season use, helping reduce early liner damage and the time spent dealing with rough spots beneath the pool. If you’re replacing a liner or installing a new above-ground pool, this pad is a smart, quick upgrade that protects your investment. Grab yours today and prep your pool base the right way.
