As mould design and production must be done by experts.
More than 25 years of experience
CBE teams have a unique know-how on the market of tunnel construction. Their strength is based on
a more than 25 year-old experience of a wide range of tunnel configurations.
Our Research & Development department allows us to implement new production technologies neccessary to improve the design of our moulds.
The mould design is a key factor in the achievement of a tunnel project
During the process of tunnel making, the TBM is often put forward, while the moulds seem to be left behind.
Yet, the overall success of the project and its delivery in time, require an early and clear view on the segment moulds production.
Additionally, the project specs (tunnel length, boring rate, etc.) will have an impact on the precast parameters and
especially on the handling systems, as well as on what kind of precast workstations are to be used.
And finally, the ability to supply within a short period of time moulds and equipment
allows to be "comfortably" ahead in segment production, even before the TBM starts up.
CBE in figures
» 230 production facilities including 110 carrousel facilities.
» 11 000 segment moulds produced.
» 10 000 000 concrete segments made.
» 2 200 km of tunnel.

The reliability and accuracy of the equipment used for the precast will have a direct impact on the global
achievement of the production site.
The design stage for moulds starts with the accurate analysis of the concrete design drawings. This phase
is an additional check-up step during the building process. It sometimes allows to track down
and rectify design mistakes that would be disastrous for the further development of the project.
The required accuracy which is part of the construction rules and law, must be followed during the whole project.
The moulds are used several hundreds of time in a row and their integrity must be guaranteed a long time.
Vibration is the dynamic part of the mould, allowing the operator to remove rapidly bubbles that may occur in the concrete and
to obtain a smooth surface of the concrete segment.
The definition of the calculation parameters and equipment for the vibration, require extraordinary skill and large experience.
