Customer Benefits

  • Simple to use products, installed using existing bolting equipment, tools and techniques.
  • Improved productivity due to fast set pumpable resin grouting system.
  • Improved product performance and superior load transfer due to assured full encapsulation.
  • Improved system stiffness due to bulbs, along the length of the bolt, at predetermined intervals.
  • Flexibility with grouting media that is either pumpable resin or cement.
  • Improved safety, fully encapsulated rapid set grouted system, avoids working under suspended load.
  • Quality assurance with cables traceable by the heat numbers stamped on the cable.
  • Effectively used as primary and secondary support.
  • Consistency in performance. Tested and proven system, uniform homogeneous mixing of pumpable resin via integrated static mixer
