Amiblu GRP pipe solutions for trenchless applications
Our promise: minimum disruptions and maximum convenience.
Jacking Pipes
When pipelines are laid in densely populated areas, protected natural habitats, or beneath heavily frequented roads, jacking is often the least disruptive solution. With their high strength, Amiblu jacking pipes are well-suited for jacking installations. Amiblu pipe design for jacking and microtunneling takes advantage of non-corrodible materials. The smooth external surface and water repellency gives low friction during jacking.
Benefits of jacking compared to traditional construction:
- No open trenches required – pipes are installed without the public noticing.
- Towns and landscapes do not suffer from the construction work.
- Falls in water table level, which affect vegetation, can be prevented.
- Due to the tight wall thickness of Amiblu jacking pipes relatively small amounts of soil are excavated and removed.
- No special storage areas are needed for materials and equipment.
- Traffic disruption is kept to a minimum.
- Amiblu jacking pipes can be installed irrespective of the weather conditions.
- Residents, nature, and the environment are protected from noise, dirt, and vibrations.
- Damage to nature is substantially lower than with the open-cut method.
- Carbon emissions are considerably lower during construction and from traffic, as congestions can be prevented.
Jacking Pipes Features:
- solutions from 300 to 3600 mm in diameter
- fully sealed and water-tight system
- corrosion-free
- long-term stiffness, approved for use under rail tracks
- high flow characteristics
- low maintenance, slime build up resistant
- abrasion resistance
- light weight and easy to transport and handle
Relining pipes
Relining creates a leak-tight “pipe within a pipe” system, which is as good as new in both structural and hydraulic terms. The method has an unbeatable advantage: the old pipeline is replaced quickly and easily and the client benefits of a pipe that is of the same quality as a new one in every way.
How it works
The relining process involves pushing or pulling the new pipes into the existing pipeline and filling the remaining annular space between the host and liner pipes with pressure-resistant grouting, usually a mixture of binding materials. This fixes the inserted pipe in position and it can take over the complete structural load capacity.
What pipes are needed
Relining installations are performed with non-circular (NC Line) or circular Amiblu GRP pipes. Amiblu relining pipes are particularly suitable for pipe rehabilitation, as they are light in weight, corrosion resistant, quality assured, easy to install and resist the load from the grouting. To put it in simple terms: relined pipes are as good as new – in every respect.
Benefits of Relining pipes:
During installation:
- Easy installation given the various jointing systems
- Constant outside diameter and simple cutting, also on site
- Little space required on site
- Installation possible irrespective of the weather
- Compatibility with other materials
For the environment:
- Little disruption to traffic
- Minimal noise disturbance
- Towns and landscapes do not suffer as a result of construction work
- Soil is not excavated
When operating the rehabilitated pipeline:
- The smooth mirror-like inner surface prevents incrustations from forming and provides adequate hydraulic reserves, even if flow rates
are low - The same quality standards, tests and external quality control as for pipes for new installations
- Relining creates a completely stable pipe system that is as good as new in structural terms
