Pool Liner Pad for Above Ground Pool - Heavy Duty 8oz/m² Felt Underlayment Pad, 40% Thicker Rectangle Pool Pad,Heat-Pressed Under Pool Mat for Superior Puncture Resistance (18*9ft, Rectangle)

Don't Gamble with a Thin Pad. Your pool liner is a major investment. Shield it with 230g of professionally engineered, heat-pressed defense. Why settle for a 200g blanket when you can have a 230g shield? Our heat-pressed technology delivers consistent density where cheaper geotextiles fail. Rocks and roots don't care about your summer plans. Our ultra-dense felt pad does. Install confidence under your pool. Thicker isn't just a number. It's 40% more material standing between your liner and the ground. That's real protection. Choose the base your pool deserves. Select your size—from 11x7.5ft to 12x20ft—and build your oasis on a foundation of confidence.

• 【Engineered 40% Thicker for Maximum Defense】 At 230g/m² (8oz) and a full 2mm thick, our pool liner pad is significantly denser and offers 40% more thickness than common 200g pads. This substantial barrier provides unparalleled protection against punctures from stones, roots, and debris under your above ground pool.
• 【Heat-Pressed Technology Ensures Consistent Density】 Unlike uneven, needle-punched geotextiles, our pad is made with industrial heat-pressed felt. This process creates a uniformly dense, non-woven fabric with no weak spots, guaranteeing reliable puncture resistance across the entire pool underlayment pad.
• 【Superior Material for Long-Term Durability】 Constructed from high-grade polyester felt, this above ground pool pad is built to last. It won't degrade or thin out prematurely, providing a stable, protective layer that extends your pool liner's life for seasons to come.
• 【Creates a Smooth, Comfortable Base】 The dense, flat surface of this under pool mat eliminates ground imperfections, providing a smoother bottom for your above ground pool liner. This not only protects but also adds a layer of underfoot comfort.
• 【Simple Installation & Custom Fit】 Just roll out the pool tarp for under pool on level ground within your pool frame. It can be easily trimmed with a utility knife for a perfect fit around any rectangular pool or round pool layout.
• 【Efficient Packaging & Handling】 Thanks to the compact density of heat-pressed felt, this heavy-duty pool pad ships in a manageable package without the excessive bulk of lower-quality, high-loft materials, making it easier for you to handle.
• 【A Smart Investment in Pool Care】 Avoid the cost and hassle of premature pool liner replacement. This premium pad is the most cost-effective insurance you can buy to safeguard your swimming pool investment from ground damage.
