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

TopHat LJR system

USAGE:

The Cosmic “Top Hat” UV light cured (GRP) lateral connection sealing system uses a Polyester impregnated corrosion resistant fiberglass insert. It can reach 6” into the lateral and creates a 3″ “brim” in the main pipe. The TOP HAT system is the fastest method of repairing sewers world-wide. Problem areas can be repaired within 12 to 15 minutes. The materials used take only seven minutes to set, avoiding the need for by-pass, pumping the existing sewer system or creating prolonged traffic jams and delays.

HOW WE DO IT:

The laminate is placed on the applicator, driven to the opening and inserted by air pressure. UV light cured in a “flash” – 7 minutes!

Panel Lok uPVC Manhole Lining System

USAGE: 

Panel Lok is designed as a bonded structural liner which forms a composite pipe section with the host pipe. Long term bond between Panel Lok liner and grout, and bond between grout and existing pipe, will transfer shear stress generated by composite action.  

Panel Lok – 17/300 (Extra Heavy)  Used for Corrosion protection and structural enhancement of gravity and low pressure pipelines DN800mm to DN1400mm and of maintenance holes and wet well chambers. Other profiles are available to suit client sizing needs.

HOW WE DO IT:

After the manhole is pressure washed the Panel Lok profile is fed through the manhole lid and spiral wound into place by hand and interlocked with a joining strip. There is minimal loss of cross section as its formed hard against the host walls. The top and bottom of the liner will be sealed with Sewpercoat with no waiting time on curing and no acid washing surfaces compared to other systems. Once the liner is installed grouting is pumped behind the liner in 1 meter lifts to complete the structural bond.

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.

HOW WE DO IT:

  • CCTV inspections of mains and laterals
  • Flow monitoring and Modelling
  • Asset Management
  • Rehabilitation methodology recommendation
  • Project Management
