FOSROC Renderoc HB40

High-Performance Concrete Repair Mortar

Fosroc Renderoc HB40 is a shrinkage-compensated repair mortar specifically engineered for use with embedded galvanic anodes. It is the ideal solution for reinstating large areas of reinforced concrete where low permeability and high-build characteristics are essential.

Key Applications

Renderoc HB40 is primarily designed for the structural repair of columns and beams. Due to its low fresh wet density, it is exceptionally suitable for overhead repair work and soffits. It can be used for:

  • Large-scale reinforced concrete reinstatement
  • Overhead repairs and soffits
  • Localised patch repairs
  • Projects requiring compatibility with Galvashield XP incipient anode protection and Cathodic Protection systems

Note: For lower strength concrete, consider Renderoc HB25. For higher strength requirements, use Renderoc HB70.

Advantages & Benefits

  • Strength Compatibility: Designed for concrete in the 30 to 45MPa range.
  • Durability: Abrasion-resistant and low permeability against water, CO2, and chlorides.
  • Precision: Shrinkage-compensated for long-term dimensional stability.
  • Efficiency: Wet-spray compatible for faster application; pre-bagged for consistent site quality.
  • Safety: Complies with AS/NZS4020:2005 for use in potable water environments.
