It is only possible to eat the geomembrane at an edge, fold, or seam onto which the animal can grip. Since PVC geomembranes have 80% less field seams than polyethylene geomembranes, the likelihood of having an edge, fold, or seam is significantly less. However, it is important to note the following information about PVC geomembranes:
1. they possess no compounds that have any food or nutritional value to rats and rodents,
2. the materials are not addictive, and
3. the reason for an animal eating through a geomembrane is probably to obtain access to the other side for food, warmth, or some other reason.
