Abstract
An indoor accelerated exposure experiments and immersion experiments were conducted to evaluate the durability of geomembrane liners. This study specifically examined mechanical properties and surface profile changes. In the indoor accelerated exposure experiments, mechanical properties declined little by little and cracks were observed on the surface of all evaluated geomembrane liners. But, the geomembrane liners' durability was determined to be more than sufficient, and surface change was improved greatly by the protective covering. In the immersion experiments, the influence of various liquids on each liner become clear.
