Superior Sealing for Water-Retaining Structures

PVC Water Stopper provides robust sealing for construction and expansion joints, ensuring no water seepage in concrete structures. Manufactured to stringent IS 15058 and ISO 9001:2015 standards, it resists harsh chemicals and environmental wear, making it a reliable solution for civil engineering projects like reservoirs, dams, and basements. Its flexibility and durability prevent leakage, extending the lifespan of your concrete installations.


Optimal Flexibility and Strength

With a tensile strength of 13 MPa and an elongation at break of at least 250%, this water stopper delivers excellent performance under pressure and movement. Its Shore A hardness of 65 5 ensures a fine balance of flexibility and solidity, adapting to structural expansion and contraction without compromising on integrity. This flexibility, combined with chemical resistance, makes it indispensable for demanding construction environments.
