EIR™ is a two-component, 100% solids, high strength, solvent-free epoxy resin for crack injection.  Due to its high rate of penetration into porous substrates and excellent adhesion to concrete and masonry, EIR™ provides for permanent bonding even of smallest cracks and restores structural integrity.

Key Features

  • Low-viscosity consistency for deep penetration of concrete cracks.
  • Good chemical resistance to protect concrete slabs and decks.
  • Resistance to creep and stress.
  • Low odor formulation.
  • Shrinkage free hardening.
  • High mechanical and fatigue strength.
  • Cures even under dynamic stress.


  • Pressure-inject horizontal, vertical or overhead cracks for a structural repair of concrete & masonry structures.
  • Mix with aggregate to repair concrete spalls and voids as an epoxy repair mortar.
  • Use to fill and seal voids and cracks in structures such as bridges and other civil engineering buildings, industrial and residential buildings, columns, beams, foundations, walls, floors and water retaining structures.
  • Bonding of structural elements
  • Consolidating steel sheet injection.
  • Solidification of hollow core screed.
  • Injection of construction joints.
  • Solidification of open-poured concrete structures.
