Geomembranes are generally resistant to damage or consumption by animals due to their synthetic composition and smooth surface. Materials such as high-density polyethylene (HDPE) or polyvinyl chloride (PVC) are not attractive to animals for feeding or nesting purposes.
However, in certain environments where animals may be present, additional protective measures such as fencing or deterrents may be necessary to prevent physical damage. Regular inspection and maintenance can help detect and address any potential damage early
