Sika® FerroGard®-300 DuoCrete

Activating Mortar for Hybrid Galvanic System

Sika® FerroGard®-300 DuoCrete mortar is used in the installation of the Sika® FerroGard® Duo Hybrid Anode range into corrosion damaged reinforced concrete. The Sika® FerroGard®-300 DuoCrete mortar is pre-mixed and packaged in a sealant tube and applied into pre-drilled holes in the concrete before the anode is inserted to generate an embedded unit. The Sika® FerroGard®-300 DuoCrete mortar facilitates activation of the Sika® FerroGard® Duo anode units in both applied current and galvanic current modes of operation. The cure time and physical properties have been designed to simplify installation and optimise performance.

  • Specially formulated for application.
  • Pre-mixed for ease of use.
  • Single component.
  • Simple installation.
  • Long shelf life.
  • Eliminates inconsistency associated with on-site mixing of mortars.
  • Minimal site labour requirement reduces costs.
  • Absence of site batching minimises waste.
  • Cost effective corrosion control solution.

System information

System Structure

Sika® FerroGard®-300 DuoCrete is used in combination with Sika® FerroGard® Duo hybrid anodes.

Other components can be used together with the hybrid anodes:

  • Monitoring equipment.
  • Reference electrodes such as Sika® FerroGard® MN 15.

Application

Application Information

Ambient Air Temperature

Sika® FerroGard®-300 DuoCrete mortar shall not be applied at temperature below +5°C.
Application steps

APPLICATION

Application shall be in accordance with the Sika® FerroGard® Duo Method Statement  and is summarised as follow:

Sika® FerroGard® Duo anodes are typically installed at a spacing of 350-500 mm.

Sika® FerroGard® Duo anodes are installed into pre-drilled holes of 30 mm diameter with the depth being dependent on the size of anode used. The Sika® FerroGard®-300 DuoCrete mortar is ready to use and gunned into the holes with a standard cartridge gun and must encapsulate the anode to ensure a large active surface area.

Following connection of the Sika® FerroGard® Duo anodes, a current is applied for 1 week after which time the power supply is removed and the assembly can be covered with a repair mortar.
