ZENA-SEAL (ZSWP100) is a water proofing membrane developed by Zenith Rubber. The rubber membrane has 100 % EPDM polymer content making it an ideal choice for the water-proofing of roofs, swimming pools, foundations for civil constructions, soak pits for animal feed, gobar gas plants, canals, etc. With a life that spans 20 years ZENA-SEAL (ZSW100) is the best choice for waterproofing applications.
ZENA-SEAL (ZSWP100) is produced in accordance to ASTM D4637 and ASTM 6134. The sheet conforms to all requirements for non-reinforced black EPDM rubber sheet for use in waterproofing applications.
ZENA-SEAL (ZSWP100) single ply black membranes are light weight and have exceptional long lasting elasticity permitting the materials to withstand Building movement, Expansion - Contraction of Building surfaces, High resistance to Ozone and weather as they are known as “Crack-less Rubbers”, Low Specific gravity - lightest among all rubbers, Widest Temperature range from - 50°C to + 150°C, Excellent Steam and Water Resistance.
