The material choice is also impressive. The non-woven fabric used in this pad is not just durable but also breathable.

From my experience, proper ventilation under the pool is crucial to avoid moisture buildup, which can lead to mildew or other damage. The Belmeri pad’s design ensures the area beneath the pool stays dry and well-ventilated, which adds another layer of longevity to my pool investment.

Installation ease was definitely a plus point for me.

3. Abimars Thicker Pool Liner Pad for Above Ground Swimming Pools, 12 Foot Round Pool Mats for Pool Bottom, Seamless Comfort, Double Density Puncture Resistant, Black

When I first came across the Abimars Thicker Pool Liner Pad for Above Ground Swimming Pools, I was immediately intrigued by its promise of robust construction and durability. This 12-foot round pool mat is made from a tough, industrial-grade geotextile blend of polyester, acrylic, and cotton fibers. What really stands out to me is that it’s 1.5 times thicker than similar products on the market. This thickness isn’t just a number—it translates to exceptional resistance against punctures, longer lifespan, and complete imperviousness to light, which means the material won’t degrade quickly under sunlight exposure. For anyone who wants a pool liner pad that can truly withstand the test of time and rough outdoor conditions, this product sets a high bar.

Another feature I appreciate is the seamless comfort and double density design. Unlike many pool liners that have a center seam which can be uncomfortable and prone to wear, this pad is seamless, offering a consistently flat and comfortable feel underfoot. The double density is a major plus—it effectively blocks light and stops grass and roots from growing underneath the pool, which can be a huge headache for pool owners. This ensures the surface beneath remains smooth and grass-free, which not only looks better but also protects the pool liner from damage caused by sharp roots or uneven ground. This design detail shows a clear understanding of what pool owners need for a worry-free swimming experience.

It’s also honest of the manufacturer to clarify that while this pad offers limited cushioning, it excels in puncture resistance and durability. I find this straightforward approach refreshing because some products promise soft cushioning but fail to deliver on durability. Here, the Abimars pad weighs twice as much as competing products of the same size, providing superior defense against punctures and abrasions. However, if you’re specifically looking for thick cushioning like sponge pads, this might not be the best fit. Instead, it’s designed to offer subtle floor cushioning combined with rugged protection—a trade-off I consider reasonable and practical for above-ground pool use.

Installation is another area where this pool liner pad shines. The soft, smooth surface is versatile enough to be laid directly on various floor types such as grass, gravel, or concrete without extra preparation like adding fine sand. This simplicity can save time and effort during setup. Additionally, the pad offers excellent heat insulation, which I found impressive because it shields feet from hot outdoor floors during summer. It also helps keep the pool liner itself cool, contributing to a more pleasant swimming environment on hot days.

Finally, the ultimate protection features of this mat sealed the deal for me. Its high-density construction resists abrasion and prevents bumps and friction between the pool liner and the floor, which are common causes of damage. The water-permeable and non-slip surface adds an important safety element, reducing the risk of slipping when getting out of the pool. Moreover, acting as a vapor barrier, it prevents water corrosion on metal parts in steel-walled above-ground pools, extending the overall durability of the pool structure. This comprehensive protection makes it a smart investment for anyone serious about maintaining their pool in top condition.

Feature	Benefit	Why It Matters
Robust Construction (1.5x Thickness)	Exceptional puncture resistance and longevity	Ensures durability and protects the pool liner from damage
Seamless Comfort & Double Density	Flat, comfy feel without center seam; blocks grass/root regrowth	Provides a smooth, grass-free surface for worry-free swimming
Limited Cushioning with Superior Defense	Subtle floor cushioning with strong puncture resistance	Balances protection and comfort honestly; ideal for durability
Easy Installation & Heat Insulation	Can be laid on gravel/grass/concrete; keeps feet and liner cool	Simplifies setup and enhances swimming comfort in hot weather
Ultimate Protection (Abrasion resistance, Vapor Barrier)	Prevents bumps, slips, and metal corrosion	Extends pool life and improves safety around the pool area

if you’re looking for a reliable, durable, and thoughtfully designed pool liner pad, the Abimars Thicker Pool Liner Pad offers a compelling combination of features. It’s built tough to protect

Having a protective layer that effectively guards against such damage gives me peace of mind and can save a lot of money and hassle in the long run.

Another aspect I appreciate is how the pool liner pad offers a cushioning effect by creating a flat, soft base beneath the pool liner.

The sizing and ease of installation are also worth noting. The pad fits a 24-foot round pool perfectly, and since no additional tools or complicated materials are needed, setting it up is straightforward.

This flexibility means it can accommodate a variety of pool types without fuss, making it accessible for most pool owners.

Maintaining a clean and tidy pool area is often a challenge, but this liner pad helps by providing a smooth, waterproof surface beneath the pool. It prevents debris from the ground from mixing with the pool water, reducing cleaning time and maintenance costs.

Buying Guide for Underneath Protection Pad for Above Ground Pool

Why I Needed an Underneath Protection Pad

When I first set up my above ground pool, I realized the importance of protecting the pool’s bottom from sharp objects, rough surfaces, and general wear. An underneath protection pad acts as a barrier between the pool liner and the ground, preventing punctures and extending the life of the pool. It also adds a layer of comfort when stepping inside the pool.

Material Matters: What I Looked For

The material of the protection pad is crucial. I chose a pad made from durable, puncture-resistant materials like polyethylene or polypropylene. These materials are water-resistant and provide cushioning. I avoided thin or cheap fabrics that could tear easily or degrade under the sun.

Size and Fit: Matching My Pool Dimensions

I made sure to measure my pool’s diameter and height before purchasing a pad. The pad should cover the entire base of the pool without being too small or excessively large. Some pads are designed to fit specific pool shapes, such as round, oval, or rectangular, so I selected one that matched my pool shape perfectly.

Thickness and Cushioning: What Worked Best for Me

Thickness plays a big role in protection and comfort. I found pads between 0.5 to 1 inch thick provided good cushioning without making setup difficult. Thicker pads offer more protection but can be harder to handle and store.

Ease of Installation and Maintenance

I appreciated a pad that was lightweight and easy to lay down. Some pads come with adhesive backing or interlocking features, which can simplify installation. Maintenance is also important; I chose a pad that was easy to clean and resistant to mold or mildew.

Durability and Weather Resistance

Since the pad stays outdoors, it needs to withstand sun exposure, moisture, and temperature changes. I looked for UV-resistant materials that wouldn’t degrade quickly. A weather-resistant pad ensures long-lasting protection for my pool investment.

Additional Features I Considered

Some pads offer anti-slip surfaces or double-layer construction for extra durability. Others include drainage holes to prevent water pooling underneath. While not essential, these features added value and peace of mind for me.

Budget and Value for Money

I balanced cost with quality, knowing that a cheaper pad might not offer lasting protection. Investing in a mid-range pad gave me confidence that my pool liner would stay intact for seasons to come without frequent replacements.

Final Thoughts From My Experience

Choosing the right underneath protection pad made a significant difference in maintaining my above ground pool. It protected the liner, improved comfort, and extended the pool’s lifespan. Taking the time to consider material, size, thickness, and durability helped me make an informed decision that I’m happy with.
