Our Glass Reinforced Polyester (GRP) jacking pipes offer high axial strength for trenchless micro-tunnelling and relining applications.

GRP jacking pipes are typically utilised in the trenchless construction of water and wastewater pipelines. Other applications include road/rail culverts, ducts, asset encasement and pipe relining.

  • DN300 to DN3000 pipe diameters available.

  • SN20,000 to SN1,000,000 ring stiffness.

  • Stainless steel & GRP coupling options available.

  • Light weight and corrosion resistant.

  • Grout injection nozzles, customised fittings & manholes available.

  • ISO25780 accredited & WSAA appraised.

Overview

Superlit GRP jacking pipes are designed to meet the exacting demands of pipeline construction and rehabilitation using micro-tunnelling and pipe-relining methods.

GRP jacking pipes are recognised for their corrosion resistance, excellent structural characteristics and their and ability to withstand the extreme axial forces imparted during the pipe-jacking process.

Applications

Our GRP jacking pipe is suitable for use in pressure, non-pressure and trenchless applications for potable, non-potable, industrial, drainage and wastewater systems.

  • Water
  • Sewage & wastewater
  • Pipe-relining
  • Road & rail culverts
  • Asset encasement (e.g. protection for pressure pipelines)
  • Ducts

Advantages

The GRP Jacking pipe has been engineered to deliver a range of features and benefits that make it suitable for the applications above, including:

  • Superior axial compressive strength
  • Excellent hydraulic performance
  • Smaller tunnel diameter and reduced spoil volume
  • Lower jacking forces required during installation
  • Smaller entry/exit pits
  • Longer drive lengths
  • Faster construction time and lower installation costs
  • Reduced environmental disturbance and social costs
