Poolergetic 15-FT Round Pool Liner Pad (Black) - Felt Underlay for Puncture & Weed Protection

This heavy-duty black pool under-mat gives an extra layer of protection between the ground and your above-ground pool liner. Made from dense felt, it reduces abrasion from rocks, roots and rough surfaces, insulates the pool floor from hot summer ground temperatures, and helps keep weeds from pushing through. The pad comes pre-cut for a 15-foot round pool but is easily trimmed to suit uneven sites or non-standard shapes.

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

The felt material acts as a shock-absorbing cushion between the ground and the vinyl liner, lowering direct pressure from sharp debris and metal supports. Its thickness and durability slow down abrasion and reduce the chance of small punctures turning into larger tears.

• Thick, high-density felt resists cuts from rocks and glass
• Creates a smooth, even base to prevent liner pinching
• Reduces rubbing against metal frames and connections

Will it help keep the pool cooler and protect feet on hot surfaces?

Yes — the pad provides thermal insulation that helps buffer heat transfer from hot ground surfaces into the pool. That keeps the liner and pool water from warming rapidly and makes the floor more comfortable to stand on after exposure to sun-heated ground.

• Soft surface reduces hot-foot discomfort on warm days
• Insulating layer slows heat conduction into pool water
• Suitable for grass, gravel, concrete, and compacted soil

Is it easy to install and fit different pool shapes?

Installation is straightforward: lay the pad on a cleared, leveled area, center the pool on top, and trim any excess with scissors. The pre-cut 15-foot round shape fits most standard round above-ground pools, and the felt is simple to custom-fit for oval or irregular layouts.

• Pre-cut for quick placement under a 15-ft round pool
• Trim-to-fit design lets you adapt to non-standard footprints
• Lightweight and flexible for fast setup and storage

How does the pad help control weeds and extend pool life?

The mat provides a physical barrier that discourages weeds and root intrusion beneath the pool, reducing pressure points that can damage liners over time. By preventing direct contact with soil and metallic parts, it also helps minimize corrosion risk and prolongs the usable life of the liner and frame components.

• Acts as a weed barrier to stop shoots from piercing the liner
• Separates metal parts from damp soil, lowering rust exposure
• Supports even weight distribution to reduce liner stress
