Firestone Pond Liner


Firestone has been producing rubber polymers for over 100 years with the first use of Firestone EPDM liner in an irrigation lagoon in Spain in 1973 (it’s still going strong!), so you can be sure that you are getting the best when you choose Firestone for your pond or lake liner.

The preference of many landscapers and building professionals Firestone pond liner is suitable for a variety of applications from garden ponds to reservoirs, lakes and lagoons.

For most applications, Firestone pond liner can be cut to the size required for your pond from rolls supplied directly from the Firestone factory, without the need for sheets to be joined in our factory, then simply trimmed to shape on-site.


Why Choose Firestone Pond Liner?

Highly durable: As EPDM is not affected by weather factors (UV, ozone, varying temperatures or frost), the liner is incredibly strong; it won’t crack or split. 

Low maintenance: Having been formulated to not suffer from microbial attacks or algae growth, this liner requires very little ongoing maintenance.

Very flexible: The flexibility of the liner means that it will conform to shelves for planting, waterfalls and vertical structures, allowing for easy installation.

Human, fish and animal safe: Firestone PondEasy is certified safe for humans, fish and animals, and is also environmentally friendly, having been produced in the USA to ISO14001 and ISO9002 standards.

Onsite joins: Firestone pond liners can be joined together using QuickSeam Tape, with QuickSeam FormFlash used for special detailing, to help achieve more complicated designs.

Aftercare: In unfortunate cases, you may require a pond liner repair kit. Containing everything you need to repair small holes within your liner, it is an immediate solution to repair any damage that may have occurred to the liner.

Size Guide

Firestone Pond Liner is sold by length (in metres), cut from large sheets varying from 4.5m to 15m wide and up to 30m long. This means you can get a sheet up to 15m x 30m.
