For applications that require an open basin, Atlantic's Flexible Basins are the easiest way to waterproof your block installation. Reinforced 28mil PVC construction with fold-out flaps and punched glue points anchor liner under capstones, for security and durability. Unlike improvised EPDM liner basins, wielded corner construction eliminates folds and wrinkles, for a neat, professional appearance.
Available in tan, gray, and black to compliment any surrounding hardscape up to 8ft wide.
Includes backing plates and bulkheads for submersible or external pumps. Use Cord Seal Fittings to pass cords.
