Abimars 18 ft Above-Ground Pool Pad — Extra-Thick Seamless Cushioning, Moisture-Blocking Protection

This durable pool pad is engineered to sit beneath an 18-foot above-ground pool and provide a continuous, cushioned layer between the liner and the ground. Crafted from industrial-grade geotextile and a polyester/acrylic/cotton composite, it replaces patched or seamed underlays with one true round piece that resists tearing, blocks light, and reduces abrasion. The design focuses on comfort underfoot, edge-to-edge coverage, and moisture blocking to help preserve your pool liner and frame.

How does the pad protect my pool liner from punctures and wear?

The pad uses a high-density composite that is roughly twice as dense as typical underlays, giving it stronger puncture resistance and longer life. Because it’s cut from a single sheet without stitched seams, there are no weak lines where wear usually starts, and the smooth surface lowers friction against the liner.

• Industrial geotextile backing for ground resistance
• Thicker composite top layer to absorb sharp-point pressure
• No stitched seams to prevent separation and tear propagation

Will it improve comfort and temperature retention for my pool?

The extra-thick, high-density construction creates a cushioned surface that feels cooler on hot ground and softer underfoot than bare earth or thin pads. When paired with a solar cover, the pad reduces heat loss through the bottom, helping water warm more evenly and retain temperature better overnight.

• Plush but firm cushioning for barefoot comfort
• Thermal resistance to reduce bottom heat loss
• Keeps the liner elevated from hot or cold ground surfaces

Does the pad stop moisture and protect the pool frame from corrosion?

The dense, moisture-blocking material acts as a barrier to ground dampness, limiting capillary moisture transfer that can accelerate frame corrosion. Combined with full edge coverage, it helps keep metal components drier and reduces long-term exposure to rust-promoting conditions.

• High-density fabric blocks ground moisture
• Full round cut prevents exposed liner edges from contacting soil
• Reduces risk of metal frame contact with wet ground

How simple is installation and maintenance for an 18-foot pool?

Because the pad is a single, true round sheet sized for an 18-foot pool, installation is straightforward—lay it smooth on a leveled base and set the pool over it. The material is wear-resistant and requires minimal upkeep: periodic cleaning and ensuring the pad remains flat and free of sharp debris is usually all that’s needed.

• One-piece, true round shape for quick positioning
• Durable surface tolerates routine use with little maintenance
• Easily cleaned with a broom or hose when needed

Who is this for: The Abimars 18 FT Extra-Thick Seamless Pool Pad is ideal for homeowners with an 18-foot above-ground pool who want a long-lasting, single-piece underlay that improves comfort, prevents punctures, and protects both liner and frame from moisture and abrasion. It suits DIY installers who prefer a fast, reliable setup and anyone replacing thin or pieced pads with a professional-grade, full-edge solution.
