Amiblu GRP pipe solutions for trenchless applications

Amiblu GRP 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.

Hobas jacking pipes
Flowtite jacking pipes

Hobas pipe designed to withstand high jacking forces. Typically used for jacking under structures like roads and railways. Water jetting resistant according to DIN 19523.

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.

Benefits of Amiblu jacking pipes:

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
service life of more than 150 years

Amiblu GRP 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.

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. 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 Amiblu relining pipes:

Benefits 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

Benefits 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

Benefits 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 – perfect rehabilitation
Seamless quality throughout the complete rehabilitated system
