While the life expectancy of a geomembrane liner can vary, high-quality liners can last over 30 years when maintained well. This depends on the material composition, installation quality, environmental conditions, and the specific application. Generally, high-quality geomembranes made from durable materials like HDPE or PVC can have a service life ranging from 20 to 30 years.
Factors such as UV exposure, temperature fluctuations, chemical exposure, and mechanical stresses can affect the longevity of the liner. Regular inspection, maintenance, and repair can help extend the lifespan of the geomembrane.
