Flowlock SRM R4 560 - Rapid Cure Structural Concrete Repair Mortar

Flowlock SRM R4 560 Structural Repair Mortar is a rapid cure, polymer-modified, fibre reinforced structural repair mortar containing corrosion inhibitors. R4 rated (EN1504:3)

The Microsilica content creates high resistance to chemical attack and the 10 minutes typical cure time allows very fast repairs of up to 50mm thickness per layer

  • Large range of structural concrete repair applications
  • Repair of structural concrete in vertical or overhead applications
  • Repair and maintenance of buildings damaged by aggressive environments, such as sulphates, acid rain, atmospheric pollution etc
  • Repair of structural concrete damaged by the effects of carbonation
  • Structural concrete repair affected by corrosion of reinforcements in marine environments
  • Single Component - mix only with water
  • Solvent-free - odourless
  • 10 minutes typical cure time allows very fast repairs of up to 50mm thickness per layer
  • Microsilica content in the cement base provides very good resistance to chemical attack, including sulphates
  • Corrosion inhibitors prevent corrosion from chlorides
  • High resistance to carbonation penetration
  • Very high mechanical strength and impact resistance
  • Good viscosity allows applications in successive layers
  • Fibre reinforced for additional strength
