Our Services

The services which can be undertaken independantly or as part of a larger project include the following

Trenchless Pipe Relining - AM Liner II

Fold and Form Structural uPVC Liner

USAGE: Relining sewer and stormwater pipelines 100mm to 375mm in diameter with our Licenced AM Liner II uPVC fold and form liner system.

HOW WE DO IT:

Specific lengths are cut to measure and softened through a steaming process

  • Liner is then attached to a winch and pulled into place inside the existing hose pipe
  • Compressed air is then used to expand and form the pipe tightly to the inside of the host pipe

Trenchless Sectional CIPP Ambient cure Patch Repairs & Relining

USAGE:

Sectional patching of sewer and stormwater pipelines, including lateral house connections, 100mm to 600mm diameter.

HOW WE DO IT:

A fiberglass reinforced matting impregnated with an epoxy resin is cut in lengths ranging from 1-4.5m to repair localised damage.

  • The patch is wrapped around an inflatable packer and pulled into the line from the closest manhole
  • Air is used to inflate the packer and compress it against the host pipe
  • This system can be used for localised repairs or a full pipe line relining if required

Cutting Protruding Laterals

USAGE: Lateral pipe connections to mains line are often not constructed very well and protrusions of up to 50mm are common place.

HOW WE DO IT:

PipeTech has 2 systems that can be used depending on the requirements:

  • KRE Robotic cutter
  • Torpedo cutter which is a rotary cutting tool placed in a liner and is largely mechanical

Lateral Cutouts

USAGE: After lining or patching over a live lateral connection it is necessary to reinstate the lateral by cutting a hole through the liner or patch

HOW WE DO IT:

PipeTech has 2 systems that can be used to reinstate lateral connections:

  • Robotic cutter
  • Electro-mechanical cutter with specialised heads

Drain Unblocking & Root Cutting

USAGE: Due to cracked pipes and joint failure often drains block as a result of root intrusion or protrusions  backing up solid material in the pipe.

HOW WE DO IT:

Drain Unblocking
The methods by which Pipe Technologies Ltd unblock drains are: 

Root Cutting

The methods by which Pipe Technologies Ltd cuts roots are:

  • High pressure water blasting similar to that used for unblocking drains can usually cut through small fibrous root systems.
  • If the roots are substantial then Robotic Cutters or Torpedo cutters are used along with either the Electro-Mechanical machine or Water blaster.

 

CCTV Inspections

USAGE: In order to check our work we utilize a pushrod CCTV camera.

Engineering Consultant

USAGE: Our clients often require PipeTech expertise to help manage their network to best decide where to spend their budgets for best advantage.
