Poolvio 18ft Round Above-Ground Pool Liner Pad — 250 g/m² Geotextile, Puncture & Weed Barrier

Poolvio's 18-foot round geotextile pool liner pad cushions your above-ground pool floor, shields the liner from punctures and blocks weeds for longer liner life.

Installing a quality underpad beneath an above-ground pool prevents sharp stones, roots and uneven ground from damaging the liner and makes the pool surface more comfortable to stand on. The Poolvio 18-foot round liner pad is a heavy-duty, eco-friendly geotextile designed specifically to fit round pool footprints while allowing trimming for custom fits. It balances durability and softness so you get both protection and improved underfoot comfort without adding bulk.

How does this pad protect my pool liner?

The geotextile fabric creates a physical barrier between the ground and your pool liner, reducing punctures from rocks, sticks and debris. Its dense weave also suppresses grass and small weeds that can grow up into the liner over time. Because it lies flat beneath the liner, it distributes pressure and reduces concentrated wear points where the liner could thin or split.

• 250 g/m² extra-thick construction resists tears and punctures
• Dense fiber weave blocks soil contact and root intrusion
• Evenly spreads weight to minimize liner abrasion
• Cut-to-fit sizing for precise coverage beneath round pools

Will the pad make the pool floor more comfortable?

Yes — the heavy-duty fabric adds a soft cushioning layer under the liner, giving a gentler surface for feet and toys. This reduces the hard, uneven feel of bare ground and helps prevent small lumps from transferring through the liner. The result is a smoother, more pleasant pool bottom for swimmers and less movement of the liner when in use.

• Soft but supportive cushion improves underfoot comfort
• Reduces sensation of bumps and ground irregularities
• Helps stabilize liner position during filling and use

Is the material safe and environmentally friendly?

Poolvio uses a non-toxic geotextile fabric that is recyclable and suited for outdoor use around pools. The material contains no harmful additives intended for direct pool water contact and is formulated to stand up to UV exposure and moisture without breaking down quickly. Choosing recyclable geotextile reduces waste compared with single-use or chemically treated underlays.

• Eco-friendly, recyclable geotextile construction
• Non-toxic fibers safe for poolside environments
• Durable against UV and moisture for extended service life

How do I fit this pad to my pool installation?

The 18-foot round pad is sized to match typical round above-ground pools but can be trimmed with scissors or a utility knife for a tailored fit. Lay it on leveled, cleared ground before placing the pool base and liner; align the center points and cut any excess so the pad sits flush under the liner. For irregular sites, overlap multiple pads or trim to shape, ensuring full coverage along the pool perimeter.

• Place on cleared, leveled ground before pool placement
• Trim to fit with scissors or a utility knife as needed
• Overlap panels for larger or non-standard layouts
• Align center marks for even coverage under liner

Who is this for: Poolvio's 18-foot round liner pad is aimed at above-ground pool owners who want to extend liner life, eliminate weeds and improve comfort without complicated installation. It suits DIY installers, seasonal pool operators, and anyone preparing a round pool site on soil, sand or grass. If you need a simple, heavy-duty underlay that’s recyclable and easy to trim to size, this pad provides reliable protection and a better pool-bottom feel.
