Firestone EPDM Pond Liner is made from synthetic rubber (Ethylene - Propylene - Diene Terpolymer).
Firestone EPDM Pond Liner is safe for fish and plant life. It is easy to install and shows outstanding resistance to the harmful effects of ultraviolet radiation (UV), ozone, oxidation and other environmental conditions.
To work out how much pond liner you require calculate the width & length x both sides, allow extra for corners or holding the edges down. For example if your pond is roughly 1mW x 2mL x 0.4mD you will require a liner approximately 2m x 3m.
