Forepoling Systems

Forepoling ring-bit systems (also known as tube umbrella systems) are designed to be drilled with a top hammer or DTH in an umbrella shape, as secondary support in a tunnel roof, allowing weak ground or overburden to be strengthened by grouting through the casing and grouting valves into the ground.

Primary applications:
  • Forepoling or tube umbrella
  • Anchoring
  • Micro piling
  • Fibre glass face stabilisation
  • PVC foundations
