UIRWAY 21FT Round Pool Liner Pad for Above Ground Pools, [2026 New Pool Pad 300G/M² Thicker] Puncture Proof Heavy Duty Pool Ground Mat Under Pool Pad, Pools Bottom Liner Protector, Extend Liner Life

Brand: UIRWAY

Color: Black

Features:

• 300GSM Heavy Duty Heat-Pressed Geotextile Protection Pad - Engineered with 300g/㎡ high-density double-layer geotextile fabric using advanced heat-pressed technology. This process creates a tighter, more concentrated structure — noticeably stronger and more puncture-resistant than standard 200GSM pads, even though it appears more compact. Focuses on superior durability and long-term pool liner protection rather than ultra-soft cushioning.
• Effective Weed Barrier & Multi-Surface Protection - 300GSM high-density geotextile pad forms a protective shield between ground and pool liner. Blocks rocks, roots and sharp debris while preventing weed growth. Compatible with grass, sand, gravel, concrete, dirt and patios for reliable ground separation and base stability for above-ground pools.
• Precise Pre-Cut Seamless Fit for Easy Installation — Pre-sized specifically for standard 21FT round above-ground pools, perfect fit for Intex, Bestway, and Summer Waves frames. Featuring a seamless one-piece design with no center seam, it creates a smooth base. No cutting or tools needed — quick and easy setup on grass, gravel, concrete, dirt, or patio surfaces.
• Black Color Helps Warm Your Pool Water - The black geotextile material naturally absorbs sunlight, helping to warm your pool water and reduce heat loss into the ground. Combined with superior cushioning, it creates a more comfortable swimming temperature for a more enjoyable experience with your family.
• Ideal for Larger Family Pools & Gatherings - Great for 21 Foot above ground pools in spacious backyards and busy family areas. This ample size fully covers large pools for regular group use, while the reinforced high-density geotextile provides strong stability under heavy water weight and daily use. It minimizes compression, bunching and shiftin — giving your family reliable, long-lasting protection and a comfortable pool experience all season.
