Ready Mixed Non-Shrink Cementitious Grout


HARDOGROUT is a non-shrink, non-metallic, inorganic cementitious grouting compound that retains its original volume and high compressive strength. Made of selected and specifically graded natural mineral particles along with hardeners, binders and dispersing agents, it provides a virtually indestructible base that resists vibration, shock, wear & tear and pounding. The average compressive strength of Hardogrout, after 28 days curing, is more than 7000 psi.


HARDOGROUT is recommended for applications where shrinkage of concrete must be avoided. This includes but is not limited to the grouting of:

  • Steel floor grids and Bearing Plates
  • Structural columns and Foundation underpinnings
  • Heavy machinery and Equipment
  • Anchor Bolts and Dowels


Fully complies and exceeds the requirements of ASTM C-1107.


The yield of HARDOGROUT is approximately 0.40 to 0.45 cu. Ft per 25 Kg bag.
