High-Tolerance, Non-Shrink Grout

HI-FLOW GROUT is specially designed for use where high tolerance, high strength and high fluidity are required. It is formulated as a natural aggregate system with a shrinkage-compensating binder and is highly flowable without sacrificing strength or performance capabilities. HI-FLOW GROUT is formulated to provide consistent and exacting performance in critical grouting operations.

Features & Benefits

  • Highly fluid for ease in placement
  • High strength for maximum load bearing
  • Non-shrink with minimum positive expansion for high-tolerance performance
  • Non-bleeding and non-segregating at a fluid consistency
  • Does not contain any chlorides or additives which may contribute to corrosion of base structure
  • Total shrinkage compensation provides a maximum bearing surface for the greatest overall support
  • Rapid strength gain to minimize turnaround time for equipment regrouts
  • Excellent working time at high ambient temperatures


  • Heavy duty grouting of machinery and equipment
  • Structural columns
  • Crane rails
  • Bridge seats
  • Bearing plates
  • Anchorages
