What We Do
Our Services
No-Dig Pipeline
Repair Specialists
PipeMedic is a specialist in completing
No-Dig pipeline repairs. Our goal is to save our clients money, time and disruption by preventing the damage/excavation of above ground assets and surfaces.
Before you dig or remove walling, PipeMedic can diagnose your pipeline and offer a repair strategy that can be either fully trenchless or partly trenchless for the most effective pipeline repair. In doing this we save our clients time, money, disruption. We also reduce health and safety and environmental risks.
No-Dig Pipeline Repairs
Full Pipeline Rehabilitation
Cured-In-Place Pipe (CIPP) Lining
CIPP is a trenchless rehabilitation method used to repair existing pipelines. This is a jointless, seamless, pipe-within-a-pipe that increases the hydraulic performance. PipeMedic technicians assess the faulty pipeline and design the CIPP liner to be installed in accordance to the relevant loading conditions and specifications.
Brawoliner® products are extremely flexible due the special loop construction. This makes it the ideal renovation solution for defective pipes with bends of up to 90° and up to two changes in dimension. Brawoliner® has a working life over 50 years, offering an economic and environmentally friendly alternative to traditional trench and relay techniques.
| PipeMedic is a certified installer of Brawoliner® CIPP products. We have chosen this system for its superior quality and performance in the 50-400mm diameter range. |

Short Liner
Patch Repair
Patching is a short version of Cured-In-Place Pipelining. If the damage is isolated, a short repair can be installed to save a significant amount of time and money.
| PipeMedic has a wide range of patching equipment and materials for damaged pipes with diameters 50mm to 1000mm and lengths of up to 3m long. |

Lateral
Junction
Repairs
A Lateral Junction Repair (LJR) is a seal between the main and lateral connection that serves to stop infiltration/exfiltration, root intrusion and to repair any cracked joins.
Pipeline Maintenance
Root Removal
& Prevention
Roots can cause serious problems in pipelines as they continually grow and expand to seek nourishment. As they grow they decrease the flow of the pipelines, cause blockages and further deteriorate the asset. Once roots enter the system it is vital to remove them and seal up the points at which the roots infiltrated. Failure to do so will increase the damage and the cost to repair.
PipeMedic has a range of root removal equipment for both light and heavy root removal. Precision robots are also utilized in cases where roots have badly damaged the integrity of the pipeline, this allows us to carefully remove the roots without causing further damage. A trenchless repair can then be installed to seal the pipe and stop further root intrusions.

Obstruction
Removal
PipeMedic has a variety of robotic cutters and tools to remove any defects or obstructions in a pipeline without the need to dig up the pipe.
The most common types of obstructions are:
| Grout / Concrete | Rebar |
|---|---|
| Protruding Laterals | Slipped Rubber Rings |
| Broken Pipe Segments | CIPP Defect Removal |
Pipe Stop
Unused pipelines can cause significant problems for the system as they are typically not maintained, allowing roots and rodents into the system.
Pipe Stop is used for closing unused/dead pipelines ranging from DN70 to DN250. The device consists of woven fabric impregnated with an epoxy resin. The device is then pushed into place, inflated and disconnected. A non return valve keeps the device inflated long after the resin has cured and the pipeline is now closed and sealed.
Pipeline CCTV & Diagnostics
Pipeline CCTV Assessments
Ø 50—2000mm
To save money and time on drain repairs, it is important that an accurate assessments are completed by competent technicians using high quality equipment.
Our CCTV technicians complete regular third party training and are experienced in accordance to the NZ Pipe Inspection Manual.
Pipeline CCTV also plays an important role in the rehabilitation of defective pipes. Before renovation work begins, video footage is recorded to show the current condition of the pipe. With this information our diagnostics team can produce a comprehensive assessment report detailing the condition of the pipeline and the recommended repair methods. Final inspections are also conducted to prove a successful rehabilitation.
| Although PipeMedic primarily specialises in No-Dig repairs, a trenchless solution is not always the most effective solution. PipeMedic will always provide a non-bias assessment and will continue to work with top quality Drainage, Plumbing and Construction companies to provide the best fit for every situation. |
