Frequently Asked Questions

Q: What size is this HDPE pond liner and what size pond will it fit?

A: This pond liner measures approximately 300 x 200 cm (about 10 x 6.5 feet). It is well-suited for medium to large garden ponds, koi ponds, and water features. To size a liner correctly, add twice the maximum depth of your pond to both the length and width measurements, then add an extra 30–50 cm on each side for overlap and anchoring.

Q: Is this pond liner safe for fish and aquatic plants?

A: Yes. This liner is made from HDPE (High-Density Polyethylene), a material widely used in water containment applications. It contains no high-concern chemicals and is designed to be safe for use in fish ponds and water gardens once properly installed and rinsed.

Q: Can this liner be used outdoors year-round?

A: Absolutely. The HDPE material is durable and designed for long-term outdoor use. It withstands varying weather conditions and continuous water exposure, making it suitable for permanent outdoor pond installations in most climates.

Q: How do I install this pond liner?

A: Excavate your pond to the desired shape, remove any sharp stones or roots, and line the base with a layer of sand or underlayment fabric if needed. Drape the HDPE liner over the hole, press it gently into all contours, and secure the edges with rocks, turf, or edging stones. Trim any excess material once the pond is filled with water.
