Features

  • Durable Protection: Crafted from durable geotextile material, our 18 ft round pool liners provide a strong barrier against punctures, tears, and abrasions, safeguarding your pool liner from damage caused by sharp objects or rough surfaces.
  • Effortless Installation: Our pool pads for above ground pools come precut for convenience, yet they can easily be trimmed to accommodate various pool dimensions. Suitable for both soft-sided and hard-sided above-ground pools, they ensure a hassle-free installation process for all pool types.
  • Tailored for Above-Ground Pools: Engineered specifically for above-ground pools, our pool liners act as a protective barrier, shielding metal components from corrosion caused by water exposure. Installation is effortless: lay your sand barrier, place the liner pad, and construct your pool atop the liner for added durability and longevity.
  • Environmentally Friendly: Crafted from recyclable materials, our under pool padding is engineered to withstand the test of time. Its innovative design allows moisture to pass through while preventing harmful items from compromising your pool's integrity, ensuring both longevity and eco-conscious pool care.
  • Multiple Size Options: Offering multiple size options, our pool ground pads are available in a wide range of sizes specifically tailored for above-ground pools, ensuring compatibility with various pool dimensions.

    • Does what it claims
Style: Rectangle Size: 16' x 32' Rectangle
This adds an extra layer of protection for my intex pool. It’s not thick and cushy, but is sturdy and gives me reassurance as the liner that came with the pool was flimsy.

    • Pretty good protection for the underside of your pool liner, not perfect
Style: Round Size: 18' Round
The size and color of the product are exactly as shown, and the pad fits the size of the pool you ordered very well. Too early to say if it actually will prevent the liner from being cut, but since the pad is 1/6 the price of a new liner, it would only need to extend the life of your liner by 1/6 to let break even on this purchase. I can't imagine the pad doing anything less than doubling the life of the liner, so in one or two summers it should pay for itself. The only issue with the product is the description leads you to imagine your're receiving a quilted blanket made of very durable material. The fact is this is just one layer of a fairly thick felt-like material. Your will still feel any little pebbles under the pad with your feet. ... show more

I can't boast about this, nor knock it too much. It serves it's purpose. This is like a super thick felt pad, not as bulky as shown. Layed out and installed as suggested, but the texture from the weave does show through the 25 ga. liner. It's not a dealbreaker or detrimental, just not something I would invest in again. My pool has a 2-3 inch sand base layer under the liner already, so if I don't use again I am not so worried about rocks and roots. Used this hoping for a more soft and smooth bottom. ... show more

The media could not be loaded. Very nice thick padding for extra protection. Ordered a size up for extra padding on the outside. Easy to layout, and seems very durable. Would order again.

This was a life saver. The hubby and I decided to just get a pool from Sam's. But with that in mind you must prep the ground before putting up.yoir above ground pool. This cover liner is great. I would still recommend you take and smooth the ground underneath before laying it out. I was just being extra cautious for nothing to poke through. The material is light weight /felt . Its almost like the liner you put down in your garden beds to keep the weeds growing through. I really like how it's already cut perfectly in a circle shape. The size was accurate. I ordered the 18ft pool barrier. I highly recommend buying this to put over your pool area or the top fill dirt. Shipping was great 2 day. Ordered.on a Friday got.it mid Sunday afternoon which was perfect timing as I was ready to unbox the pool!! Happy Summer y'all ✌️ ... show more

Very annoyed with this product. It’s about 10” shy in width and not even close in the length. It is an egg shape leaving a great deal of uncovered areas around the”corners”. Very upset with this purchase. It’s incredibly thin for the $100 plus I spent. The company was very nice to work with. They refunded my money with no questions asked. I would have really liked to get the liner but I’m happy with the end result. ... show more
