Features
- ENHANCED POOL LINER PROTECTION: Protect your pool liner with this 180 GSM heavyweight above-ground pool mat. This dense layer acts as a tough physical barrier against punctures from stones, tree roots, debris, and sharp objects, providing a durable defense line on grass, concrete, or uneven surfaces to extend the life of your liner.
- PROTECTION & COMFORT: Protect your pool liner and enjoy added comfort with our durable PE ground mat. This waterproof and sun-resistant material creates a smooth, padded base, eliminating hard spots and helping to prevent punctures. The fade-resistant blue color blends attractively with your pool area.
- SIMPLIFY POOL SETUP: This pre-cut ground pad liner protector is sized to fit standard 18 ft round pools, with no need for extra tape or materials during installation. If you have a rectangular, oval, or custom pool, the pad can be easily trimmed to the right size, so you can get from setup to swim time quickly.
- EXTEND LINER LIFE: This heavy-duty ground mat sheet provides a smooth, protective layer between your pool liner and the ground. By cushioning the liner, it helps reduce wear and tear, significantly extending the liner's lifespan. Suitable for frame above-ground pools and inflatable top-ring swimming pools.
- PROTECT MORE THAN JUST YOUR POOL: This sturdy protective cushion layer provides a smooth, protective layer for a variety of outdoor applications. Use it not only under your swimming pool to help reduce liner wear and tear, but also for camping, covering vehicles, boats, tents, and more. The reinforced material helps shield against moisture, dirt, and other environmental factors, making it a practical choice for numerous outdoor needs.

Very nice pool liner! I wanted the circle shape so it would be easier to center the pool and then be able to mow around the pool better because we could lift the edges and mow - should be much better than the square one we had which had excessive tarp at corners. Seems sturdy.

Worked great for my 16ft pop up pool. I ruined it on one edge with my weed eater but overall very impressed with the quality. "Not weed trimmer string proof".
