Features

  • PROTECT YOUR LINER - This pool liner pad is made from a special cloth fiber that is thick and durable. Defend your liner against cuts and punctures from rocks, roots, glass and other harmful debris found on the ground. It will provide a flat base that gives an extra layer of armor for your swimming pool floor bottom prior to liner installation.
  • ABOVE GROUND POOL PAD The liner guard creates a vapor barrier on the bottom of the pool to eliminate water from corroding the metal components for steel-walled above ground swimming pools. It will give your pool floor a subtle layer of cushion and padding, making a soft pool bottom below your feet, while also protecting the liner from potential damage. Also, works ideally when placed on grass or concrete under pop-up pools for an additional protection.
  • FITS YOUR POOL SIZE There is no need for tape or additional materials to install this Rhino Pad. It is pre-measured for your specific swimming pool size. If you have a round, oval, or irregular pool size or shape, the liner guard can easily be trimmed to fit your needs.
  • ECO-FRIENDLY AND DURABLE Made of strong earthy woven material, the liner shield is a resilient geotextile fabric composed of 45% post consumer and 45% industrial recycled material that permits moisture to safely pass through. It may resemble felt with its 18 of an inch thickness, but the performance is beyond exceptional in protecting your investment.
  • LONGER LINER LIFE - Preserve your pool liner and extend its life span. Its high density and low compression construction qualities help create a resilience to all sorts of invasive elements, protecting your liner while ensuring you get the most out of your swimming pool. Note: Made in both black and white material. You may receive either black or white with your order, but both colors provide the same protective barrier. Limited 2-year warranty. Nut Grass is not covered under warranty.

  • Great Pool Underlayment Pad!
Material Type: Oval Size: 16' x 24' Oval
Not as thick as I expected, but it's quite durable and did provide a softer footing under the pool lining. It's been installed for a few months. I left a foot of the pad exposed all the way round the pool and it works great to keep grass and weeds from growing around the pool edges. I covered the overlap with rubber mulch and bordered it with paving stones. Looks great! ... show more

  • Reliable product.
Material Type: Round Size: 27' Round
Very easy to work with cut perfectly and very smooth, I have read some other reviews in which the writers were not happy because it was to thin. However, the material is meant to stop anything, such as a rock or root, from coming up from the bottom under the pool's liner and punching a hole in the pool's fool, for this the type of material and size is perfect. It is not meant to be a cushion and it does appear thin; because, it is thin; however, it is not the thickness but rather, the material which is relevant in stopping the pool fool from being punched. If you want a thick cushion or if you believe that only a thick pad will work, than honestly this is not for you. However, if you do understand that it is the type and quality of the material that stops and future damage form occurring then but thus one. ... show more

  • Suprising quality
Material Type: Rectangle Size: 16' x 24' Rectangular
As other reviews mentioned, the material is felt like. But surprisingly durable. Bought an oversize rectangle piece to fit under my Costco Bestway 12x22 pool. Created a level pea gravel bed+heavy duty tarp with the Rhino pad on top. Very easy to smooth out the pool bottom when installing with the liner under it. Pleased with the results and very comfy on your feet. ... show more

  • Item as stated
Material Type: Oval Size: 12' x 18' Oval
It is as described but thin, similar to felt. Nowhere near as thick as the photo makes it appear.

  • As Protection only, not cushioning
Material Type: Round Size: 30' Round
I find this misleading. While it may protect the Liner, it will definitely not cushing your Feet. To thin for that

  • Extra thick landscape fabric
Material Type: Oval Size: 10' x 15' Oval
There seems to be a mystery about what this product really is. It’s been called “Soft, cushioning, thick, felt-like, padding…”. It is simply a cut-to-size, nicely seamed piece of extra thick landscape fabric. The fabric is marked with which side to put down so that the seam is less intrusive. It is convenient to use, and I feel that it will keep weeds from coming through. I laid it all the way to the fence where I have plants and used it for landscape fabric around those plants. It was difficult to put metal pins in it to hold it down. That’s how tough it is! I can’t say how this is compared to other pool pads, but I like it and I’m glad I bought it. ... show more
