Application Instructions

Surface Preparation

Hydroc Micro Concrete must be applied to a clean surface free of contaminants. Bolt holes and fixing pockets should be free of dirt and debris.

Application Method


Hydroc Micro Concrete must be applied to a wet, puddle-free surface


Use a low sheer mechanical mixer to ensure proper mixing

  • Normal water requirement is 2.4 to 2.5L per 20 kg pail dependant on required viscosity.
  • Place 2 litres of water in a clean mixer bucket. While stirring gradually add Hydroc Micro Concrete and mix thoroughly for 2-3 minutes.
  • If necessary, add additional water, until a mix of the desired workability is obtained. Mix for a further minimum 1 minute. Use within 30 minutes.


Placement is by either gravity flow or by pump.

  • Mixed grout is poured one side of the void to avoid air entrapment
  • Grout is best poured over short distances to ensure this.
  • When pumping Hydroc Micro Concrete, a positive displacement pump is recommended
  • To facilitate grout compaction, use tamping, rodding or flexible strapping
  • Do not vibrate, as this will cause segregation
  • Recommended thickness of Hydroc Micro Concrete in one pour is 20 to 50 mm
  • Minimum thickness is 20 mm, maximum – in one pass is 200 mm
