Review on Protect Your Above Ground Pool With Rhino Pad 27-Foot Liner - Puncture Prevention And Eco-Friendly Fabric For Enhanced Liner Lifespan! by Christian Bennett

I used 4x4 post and top soil to make a level pool pad in my horribly un-level yard so I wanted a pad of some kind to protect against rocks. I used a medium built tarp on the bottom with this between the tarp and the pool floor. I found a couple sharp rocks as soon as we started filling the pool so I slid underneath and pulled them out. Possibly would have been ok with the Rhino pad but they were easily retrievable so I didn't want to leave them. The pad does add a small amount of padding to the floor but you'll still feel rocks and bumps through it if you leave them.
