RollAnodes are sacrificial Zinc anodes specifically designed for application in pre-drilled holes which are then embedded in an ion-conductive self moistening paste for Cathodic Protection of reinforced concrete structures.

The RollAnodes are based on rolled layers of Zinc with ion-conductive gel which, after being applied in concrete, can be surrounded with a patented ion-conductive self moistening paste keeping the anodes active during their entire service-life. The paste (Zinc Anode Activation Paste ‘ZAP’) is delivered separately in 600ml tubes which can be applied with standard manual or battery powered sealant guns.  

These anodes can be utilised in those areas where a high expectancy of corrosion is of concern. They provide a high level of corrosion protection and prevent new locations of corrosion initiating.

Long term research indicated that RollAnodes help comply with the criteria detailed in the European standard EN12696. 

Areas of application

• Bridge deck
• Viaduct beam supports and columns
• Areas of new repairs on existing structures
• Balcony facings and concrete facades
• Flooring 

Advantages of RollAnode 

• Can be used as an alternative to discrete impressed current anodes, when no current supply is available or anode feeder cable installation becomes too costly.
• High performance when used with the ZAP.
• Ideal solution for existing corrosion problems on reinforcement as anodes can be inserted in small predrilled holes.
