It is composed of PVC resin blended with plasticizers, UV-resistant agents, anti-aging additives, and stabilizers. Its exclusive formula ensures an extended service life that outperforms regular waterproof materials: over 20 years for roof use and more than 50 years for underground applications, leading to widespread adoption in construction and civil engineering projects.
