Kantaflex offers a range of copper water stops designed and manufactured from phosphorus non-arsenical copper alloy at 1.0mm thick to AS1566 or BS1172 international standards and specifications.

Kantaflex copper water stops are predominantly used in water retaining structures such as dams, which receive very high hydrostatic heads of water pressure against the joint. They provide a very high grade of performance and give resistance to certain types of chemical attack, due to their durability, integrity and strength.
