Koi Pond Liners, Underlayment, and Accessories for Sale

The right liner, underlayment and accessories can really make or break a koi pond. Pond Warehouse offers high-quality pond liners, underlayment, and essential accessories that will make your pond more functional and beautiful.

Premium Koi Pond Liners

A reliable pond liner is the foundation of any successful koi pond. Our bold pond liners come in various sizes and materials, including flexible EPDM rubber and durable PVC options. These liners are built to resist punctures, UV damage, and harsh weather conditions, ensuring long-lasting protection for your pond. With easy installation and the flexibility to adapt to unique pond shapes, our liners are an idea choice.

Koi Pond Underlayment

Underlayment is a crucial yet often overlooked component of any koi pond. Acting as a protective barrier between the soil and your pond liner, underlayment prevents sharp rocks, roots, and other debris from puncturing or damaging the liner. Our bold underlayment products are made from tough, non-woven geotextile fabric that provides excellent production and make your pond more durable.

Koi Pond Liner Accessories

In addition to liners and underlayment, we offer a wide range of pond liner accessories to ensure every part of your pond construction is covered. Our bold liner seaming tape, adhesive, and patch kits make it easy to customize and repair your liner as needed. We also carry waterfall foam to seal gaps around rocks and other water features, which help maintain the integrity of your pond.
