New Installation & Rehabilitation Design

Extend the life of your pipe networks for less. Trenchless technologies are usually cheaper and less disruptive than traditional open cut excavation.

The use of trenchless technologies to install new pipes or to rehabilitate existing pipes can be cheaper and less disruptive than traditional open cut excavation. Rehabilitation through lining, grouting, pipebursting or sliplining can be an effective method for extending the life of pipe networks and reducing overflows.

But too often trenchless technology projects fail because the techniques selected were not suitable for the situation or the wrong equipment was used, or the investigations works were inadequate or the risks of the project were not fully understood. Personnel managing rehabilitation projects need to be able to identify the potential risk factors and be able to put in place measures to mitigate them.

ProjectMax are recognised as experts in the design and administration of rehabilitation projects. We manage over $5mil worth of sewer rehabilitation works per year. The experience of ProjectMax experts creates a clear advantage when designing and specifying trenchless technology solutions. ProjectMax are a dedicated team of specialists in the design of new underground infrastructure and the rehabilitation of existing assets.


We develop rehabilitation concepts from condition assessment and evaluation up to rehabilitation planning and implementation.

We have completed rehabilitation projects to:
  • Reduce infiltration.
  • Repair pipes with Hydrogen Sulphide attack.
  • Increase the life of the pipeline.
  • Improve hydraulic flows.
  • Reduce blockage.
We are experts in the rehabilitation of pipelines by:
  • Cured in Place Lining.
  • Spiral Wound Lining.
  • Close Fit Lining Systems.
  • Pipe Bursting.
  • Slip lining.
  • Coatings.
Our expertise also includes rehabilitation of:
  • Pressure pipes for wastewater and potable water.
  • Manholes.
  • Lateral pipes.
