Sika Galvanode DAS is a distributed anode system designed to provide corrosion control or cathodic protection to concrete decks, columns, beams and walls. Sika® Galvanode® DAS anode units are distributed over concrete and masonry structures to provide global corrosion protection. The quantity of zinc provided, the anode shape, electrical components and installation procedures are customised to meet specific project requirements.

Due to this product being customisable please contact Rawlins Paints' Technical Support Team on 0113 2455450 (option 2) or send a message to [email protected] to discuss your requirements.

Individual Sika® Galvanode® DAS anode units are typically square, rectangular, oval or circular in cross section and can be supplied in lengths of up to 2.3 m. The system is quickly and easily installed to provide corrosion protection for a variety of applications.

The system can be encased in new concrete, embedded in concrete overlays, encapsulated inside reinforced concrete jackets or used in conjunction with stay-in-place forms for column protection.

Application

• Sika® Galvanode® DAS distributed anode systems are used for a wide range of applications. Specific application procedures can be developed on a project-by-project basis.
  • Please contact Rawlins Paints' Technical Support Team to discuss your requirements on 0113 2455450 (option 2) or send a message to [email protected] for more information.
• Galvanic protection shall be provided using Sika® Galvanode® DAS anode units. The distributed galvanic anode units shall be alkali-activated with a pH greater than 14 and contain zinc evenly distributed along the length of the unit. Zinc shall be in compliance with ASTM B418 Type II.
• The zinc shall be formed around a steel core which is continuous along the length of the unit.
• The anode unit shall include FRP reinforcing to resist expansion, and shall not contain intentionally added constituents that are corrosive to reinforcing steel as per ACI 222R such as chlorides, bromides, or other halides.
• Unless otherwise specified, the anode unit shall be supplied with a pair of integral heattreated, uncoated steel tie wires with loop ties to make connections to the reinforcing steel.

Limitations

• Sika® Galvanode® DAS distributed anode system is not intended to address or repair structural damage.
• Where structural damage exists, consult a structural engineer.
• Do not allow Sika® Galvanode® DAS anode units to be soaked prior to installation.
• For optimum performance, encasement concrete resistivity should be less than 15,000 ohm-cm.
• Concrete with significant amounts of polymer or silica fume may have higher resistivity.
