CONTENTS CONCRETE REPAIR CORROSION CONTROL GROUTS & ANCHORS PROTECTIVE COATINGS INDUSTRIAL FLOORING SURFACE TREATMENTS JOINT SEALANTS CONCRETE JOINTING JOINT FILLERS WATERPROOFING WATERSTOPS ROOFING TIMBER FLOORING ALPHABETICAL INDEX 91 Galvashield® CC Individual Connection Drill one rebar connection hole per unit location. Saw cut a groove approximately 6 mm wide by 12 mm deep into the concrete to interconnect the rebar connection hole and anode connection hole. *Please refer to the Galvashield CC Installation Guide for further details. Reinforcing steel connections should be made using the Rebar Connection Kit. Place the weighted end of the connector into the drilled hole until the steel coil contacts the reinforcing steel. Feed the steel connector wire through the Setting Tool and set into place by striking with a hammer. Connect the units directly to the rebar connection wire using the supplied wire connector. If installing in series, connect the units to the interconnecting cable with a wire connector (cable and wire connectors are available as the Anode Connection Kit). Verify continuity between unit locations and rebar connections with a multi-meter. A resistance of 1 ohm or less is acceptable. Drill holes as per the dimensions listed above to accommodate the anodes. Presoak the units for a minimum of 10 to a maximum of 20 minutes in a shallow water bath. Galvashield CC bedding mortar should be used to install the still wet units into presoaked (saturated-surface dry) holes. Place the mixed embedding mortar into the bottom 2/3 of each hole and slowly press in the unit allowing the mortar to fill the annular space ensuring there are no air voids between the unit and the parent concrete. The minimum unit cover depth shall be 20 mm. Place wires into grooves and top off unit holes and saw cuts flush to the concrete surface with embedding mortar. Embedding mortar should be wet cured or cured with a curing compound and protected from traffic for 24 hours. Precautions Galvashield CC units are not intended to address or repair structural damage. Where structural damage exists, consult a structural engineer. Galvashield CC anodes are designed to provide galvanic corrosion control. Corrosion control products significantly reduce or stop on-going corrosion. Concrete repairs should be completed using Galvashield XP units around the boundary of the patch prior to installing Galvashield CC units in the remaining unrepaired areas. For more information on corrosion mitigation strategies, contact Parchem. Packaging Galvashield CC units 20 units per box Galvashield CC bedding mortar 5kg bags, one bag per 20 units Rebar Connection kit 20 rebar connectors per box Anode Connection kit 15.2m insulation cable 25 wire connectors Setting Tool 1 unit per box Storage Store in dry conditions in the original unopened boxes. Avoid extremes of temperature and humidity. Units should be installed within one year. Health and Safety As with all cement-based materials, contact with moisture can release alkalis which may be harmful to exposed skin. Galvashield CC and Galvashield CC bedding mortar should be handled with suitable gloves and other personal protective equipment in accordance with standard procedures for handling cementitious materials. Mix left over water from the unit bath with cementitious material and dispose by normal means after hardening. Additional safety information is included in the Material Safety Data Sheet.
