A PVC waterproofing membrane is susceptible to damage from both human activities and environmental factors. When compromised, such a membrane loses its ability to resist heat, ultraviolet radiation, water, and physical impacts, leading to deterioration and brittleness over its lifespan.

There are ten primary reasons that can contribute to the damage of a PVC waterproofing membrane:

1. Physical punctures or cuts on the membrane.
2. Prolonged exposure to direct sunlight.
3. Exposure to high temperatures.
4. Inadequate installation practices.
5. Contact with harmful chemicals.
6. Use of incompatible roofing materials alongside the membrane.
7. Natural aging or wear and tear.
8. Improper maintenance procedures.
9. Mechanical stress applied to the membrane.
10. Severe weather conditions affecting the membrane.
