AquaJoyer 12' x 18' Oval Pool Liner Pad — Extra-Thick 250g Underlayment, Puncture & Weed Barrier

AquaJoyer's 12' x 18' oval extra-thick pool liner pad cushions and protects above-ground pool bottoms from punctures, roots, and uneven ground while creating a comfortable underfoot surface.

Installing a dependable underlayment is one of the simplest ways to protect your above-ground pool liner and improve the swimming experience. This AquaJoyer pad is made from 250g non-woven fabric engineered to block weeds, resist tearing, and create a soft layer between dirt or gravel and your pool liner. It’s designed to be trimmed and shaped to match oval pools and installs quickly on level ground, whether your pool is soft- or hard-sided.

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

The pad forms a continuous cushioning barrier that absorbs pressure from rocks, roots, and compacted soil, preventing sharp points from pressing into the liner. Its durable, tear-resistant fabric reduces friction and abrasion, extending the life of your liner without complicated hardware.

• 250g non-woven fabric resists rips and punctures
• Creates a smooth contact surface to prevent liner friction
• Blocks roots and weeds that can push through to the liner
• Fits under any above-ground pool shape after trimming

Will installation take a long time and what tools do I need?

Installation is straightforward and fast—lay the pad on leveled ground, overlap the edges slightly over the pool footprint, then trim excess. No special tools are required; a pair of sharp scissors or a utility knife and a tape measure are enough for most setups.

• Lay flat on a clean, level base
• Trim with scissors or utility knife for an exact fit
• Overlap slightly at edges to ensure full coverage
• Compatible with both soft- and hard-sided above-ground pools

How does this pad affect pool cleanliness and comfort?

By blocking weed growth and keeping debris from contacting the liner, the pad helps reduce the amount of dirt tracked into the water and lowers the chance of liner staining. The extra-thick material also provides a noticeably softer surface underfoot, making the pool bottom more comfortable for swimmers and children.

• Weed barrier reduces organic intrusion under the liner
• Smoother pool bottom limits dirt pockets and stains
• Soft underfoot feel enhances swimmer comfort
• Helps maintain cleaner water by limiting ground debris

Can this pad be trimmed for different pool shapes and sizes?

Yes—the 12' x 18' oval pad is easy to cut to size for oval, round, or custom-shaped above-ground pools. It’s flexible enough to contour to small irregularities while retaining its structure and protective benefits.

• Trim-to-fit design for oval or round pools
• Flexible material conforms to slight ground contours
• Leaves a continuous protective layer after cutting
• Available in multiple sizes for larger or smaller pools
