Galvashield® DAS

Galvashield® DAS is a distributed anode system that is quickly and easily installed to provide corrosion protection for a variety of applications, such as installation in new concrete, embedded in concrete overlays, encapsulated inside reinforced concrete jackets or used in conjunction with stay-in-place forms for column protection.

The Galvashield® DAS system is alkali-activated and comprised of high-purity zinc cast around steel tie wires with an enhanced formulated cement-based mortar with an internal pH of 14 or greater that keeps the zinc active over the life of the anode.

These long strip anodes are quickly and easily distributed over the surface of a concrete or masonry structure and connected to the reinforcing steel using tie wire connections. Once installed, the zinc anode corrodes preferentially to protect the adjacent reinforcing steel.
