Features
- 300GSM Heavy Duty Heat-Pressed Geotextile Pool Pad - Engineered with 300g/m2 high-density double-layer geotextile fabric using advanced heat-pressed technology. This creates a tighter, more concentrated structure that delivers strong puncture resistance compared to standard 200GSM pads offering excellent protection even in a more compact form.
- Weed Barrier & Puncture Protection - Our pool pads for above ground pools form a tough protective shield between the ground and pool liner. Effectively blocks sharp rocks, aggressive roots, sticks, and debris while acting as a reliable weed barrier. Compatible with grass, sand, gravel, concrete, dirt, and patio surfaces.
- Precise Pre-Cut Fit for 18FT Round Pools - Precisely sized for standard 18FT round above-ground pools, compatible with Intex, Bestway, and Summer Waves frames. The seamless one-piece design with no center seam creates a smooth, wrinkle-free base. Tool-free installation simply unroll and place. Can be easily trimmed if needed to fit various pool dimensions and works with both soft-sided and hard-sided above-ground pools.
- 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.
- Great for Large Family Pools & Active Backyards -Works well with18 Foot above ground pools and bigger family gatherings. The generous size offers full coverage for big pools. Reinforced high-density geotextile maintains stability under heavy water weight and regular use. It resists shifting, bunching, or compressing creating a reliable and comfortable base for your pool.

Size: Round-12ft
Good so far. It is thin, but the fiber weave works as intended. You don't want a fluffy underlayment! U

We bought this for our 18 ft pool. It’s really thin and feels like felt but it did give a comfy feeling from inside the pool.

This is like a dense felt pad. It fits about a foot or so larger than the perimeter of my 10x15 ft pool. I've had it for about 2 mo now and it doesn't collect debris and grass clippings as bad as I thought. It does stay wet longer than I'd prefer. I thought it would dry faster, especially being black in the sun. I put it over rubber deck tiles and it softens the bottom of the pool nicely, then gives a soft place to stand around the pool and getting in. It stays down fairly well, even in the wind. It was just like the description, which is very nice

If I’m being honest with you, it’s not at all what I had in mind. When I ordered this, I was thinking it was a pad and thicker, this is pretty much a weed/grass killer. Not thick at all. It’s actually just felt. Not worth it to me. It did fit well and the size is just as it says, but as far as durability it will probably not last that long.

Way thinner than I expected but it seems to do the job. We added a heavy tarp under it because it was so thin.

Had holes in my pool liner and this liner pad sealed those holes so it wouldn’t leak! Very happy with the thickness, fit, durability and value for the money!
