Pond liners in natural swimming ponds can last a long time, but their lifespan depends on the material and how well the pond is maintained. EPDM rubber liners typically last between 20 to 30 years, thanks to their durability and resistance to UV rays and temperature changes. Reinforced polyethylene (RPE) liners are also quite durable and can last 20 years or more with proper care.
Natural liners like bentonite clay can last as long as the installation is done correctly and there’s minimal disturbance, however they often lead to huge amounts of seepage over time. Regular upkeep, such as removing debris and checking for any damage, can help extend the life of any liner. With the right materials and care, a pond liner can keep your natural swimming pond functioning well for decades.
