Anchor Grout

HIR Anchor Grouting is a solvent free highly filled two parts Grout. After hardening, the grout has high mechanical properties capable to withstand extremely high loading, wear and chemical resistance. HIR Anchor Grout is used when the difference between the hole diameter and bar or bolt or rod diameter is ≤ 25mm.

  • HIR Anchor Grout is used for high strength corrosion resistant anchoring of bolts and bars from 12 – 25mm diameter.
  • Use in concrete, rock, masonry or brickwork where high speed of installation and early application of load is required.
  • Permanent installation of reinforcement starter bars, foundation bolts, base plates, barriers and safety fences, railway tracks, tieback anchors, reinforcement dowelling abutments, ground anchors for towers, cranes, dock sills.


  • New concrete or cementations work must be cured for 28 days.
  • HIR Anchor Grout requires rough sided, dust free holes. Uses of rotary percussive drills with air or water flushing is recommended.
  • Diamond drilled holes should be under-reamed unless necessary safety factors are incorporated. Cast holes should preferably be inverse dovetail configuration.
  • If parallel sides’ holes are cast they should be rough to provide adequate keying.
  • Bar preparation: All bars should preferably be degreased and all flaky rust removed. Bar preparation: All bars should preferably be degreased and all flaky rust removed.


  • Mix the resin part A and curing agent part B with mixer until a homogeneous, lumps free smooth consistency is achieved the grout is ready for use.
  • The grout should be poured steadily into the prepared holes.
  • The anchor bar is then pressed into the hole to the required depth.
  • Slight agitation of the bar will assist in achieving a complete bond.
  • The bar should then be left undisturbed in the required position until Grout is set.
