Overview

Load-bearing repair. Structural certified.

Structural / High-Build Repair Mortar is a high-strength, fibre-reinforced cementitious mortar engineered for structural repair of load-bearing concrete elements. Polypropylene micro-fibre reinforcement plus polymer modification enables thick vertical and overhead application without slumping.

Specified for column section restoration, beam soffit repair, and any application requiring EN 1504-3 Class R4 structural grade.

Key Features

  • EN 1504-3 Class R4 – highest structural grade
  • Polypropylene fibre reinforcement – anti-cracking
  • Vertical/overhead application up to 50 mm/layer
  • Compressive strength exceeds parent concrete
  • Sulphate and chloride resistant
  • Pre-blended – site water addition only
