Mapeshield I

Mapeshield I

Pure Zinc Galvanic Anode

Mapeshield I is a pure zinc anode for cathodic protection of reinforcing steel against corrosion in new, reinforced structures as well as structures requiring repair.

Available in lengths of 10 cm and 30 cm
Available in five different weights of active zinc content
Long-lasting delivery of protective current*
Surrounded by a special conductive paste, Mapeshield I anodes provide sufficient current to be anodic to the reinforcing steel and lower in electric resistance than other anodes that have solid, thick cementitious shells.
An optimized design that maximizes the available surface area of the zinc plates
Compliance with international standard ISO 12696, “Cathodic Protection of Steel in Concrete”
Quick and easy installation with no special tools needed
Does not require a low-resistivity mortar packed around the anode when a high-resistivity repair mortar is utilized
Can be used with concrete and concrete repair mortars with resistivities up to 100 kΩ, as specified by EN 12696 standards

^{* Protective current is influenced greatly by amount of chlorides in the existing concrete as well as rebar density in the structure.}
