Metallic Waterstops for Better Chemical and Heat Resistance

Metallic waterstop is generally made from galvanized steel, stainless steel and copper sheets. It is commonly used as a fluid-tight diaphragm that embedded in concrete structures for water retaining. It has high strength, great integrity and durability and can withstand high hydrostatic heads of water pressure against the joint. In addition, it gives excellent resistance to most corrosive or aggressive fluids leaking into the joints. Meanwhile, it is a good choice for ozone, corrosive even extremely elevated temperature environments.

To reduce the butt-welding during installation, a series of metallic waterstops including flat or vertical L, T and cross are available for all direction changes.
