Butyl rubber remains the top choice for professional pond builders and water gardeners due to its highly flexible, durable nature. It is non-toxic and does not harm any aquatic or plant life. It is long-lasting and completely UV stable so will not crack or split if left exposed to normal sunlight.
While offering the same high quality and resistances as Butyl rubber, EPDM rubber is a popular budget-friendly alternative with a shorter expected working lifetime.
Our flat sheet Butyl rubber pond liner carries a lifetime guarantee and has an expected working lifetime of around 50 years.
Our flat sheet EPDM rubber pond liner carries a 10 year guarantee and has an expected working lifetime of 20 to 30 years.
