Anjon Lifeguard 45 Mil EPDM Pond Liner
Overview
The Anjon Lifeguard EPDM liner offers everything you may ask for. As made with EPDM (ethylene propylene diene monomer) rubber, it is very flexible and hence easy to work with. You can stretch it to any shape. Therefore it is the most suitable liner to use for your koi pond, wildlife pond, and water features.
It has a thickness of 45 mil and resistance to puncture. Therefore, it will not get damaged by rocks and other sharp things that you may add to the pond.
This pond liner can withstand UV radiation and weathering effect sun, freeze, and thaw. As a result, this one lasts longer than a normal liner and doesn’t require frequent repair.
Another thing to mention about this liner is, it doesn’t contain any plasticizer. Plasticizers make liner brittle. Cracks can form easily in those liners that contain plasticizers.
