SmartLine Swirl Bottom Overlap Expandable Liner

An overlap liner is designed to drape over the top of your pool wall and be secured on the outside with coping strips. The 'expandable' feature means the material has enough flexibility to accommodate slightly dished pool bottoms or variations in depth up to 72 inches, rather than being restricted to a perfectly flat floor.

This liner is built with Lamiclear technology, which provides inherent UV and chemical resistance, so it does not require special treatments. However, maintaining proper water chemistry balance is always the best way to extend the life of any vinyl liner.

Double-welded seams provide a secondary layer of reinforcement at the most vulnerable points of the liner. This construction significantly reduces the risk of seam separation, punctures, and cracks compared to standard single-weld designs.

Each liner is hand-folded before shipping specifically to minimize the risk of deep, permanent creasing. While you may see some minor fold lines when you first unfold it, these typically smooth out once the pool is filled with water and the vinyl warms up.

Yes, 20-gauge is a standard, durable thickness for above-ground pool liners. It offers a good balance between flexibility for easier installation and the structural integrity needed to withstand daily use and pool chemicals.
