Mesh Retaining Durabar (MRD)


Rock engineers from several mines approached us wanting a yielding support system, which when grouted into the hole could also hold the weight of the mesh on primary insertion into the rock. They also needed the mesh to maintain its position as close to the rock face as possible. Several products where tested none of the them fulfilling all the criteria.

  • High ability to dissipate kinetic energy
  • High rates of energy dissipation
  • Very stiff in static conditions
  • Debonding coating inhibits corrosion
  • No special training needed for exisiting crews
  • Yields at constant load
  • Exceptional displacement range
  • Least vulnerable to shear failure
  • Easy to install
