Void Forming Tubes
Economical and easy application
Displacement pipes allow for the safe, quick and economical construction of hollow bodies in hollow plate bridges and ceilings. The dimensional accuracy, tightness and high resistance to deformation of these industrial cavity elements guarantee the implementation of the calculated static values in the structure.
Easy and flexible
Despite their low weight, the displacement pipes can be installed in the concrete without stiffening. Additionally, the corrugated profile provides a certain flexibility, which allows for the laying of displacement pipes also in a bent course. Despite these characteristics, the resistance of the pipe to longitudinal deformation is so high that the distances between the lift prevention locks can principally be adapted to the stability of the applied supports.If the displacement pipes are to be secured against lift, it is recommendable to apply the specifically developed Hydra single and double anchoring elements. They are tested for their static properties and guarantee utmost avoidance of showings, above all of rust stains at the bottom of the ceiling.
The different assembling and disassembling methods of the supports allow for compliance with the individual requirements in the individual structures. it is possible to install and to remove the lift prevention locks exclusively from above, if this should be very difficult or impossible from below, due to the specific conditions.

Use in Ceiling Areas
The use of displacement pipes made by wbr makes modern concrete building more economical and faster – either with site-mixed concrete or with ready-mixed concrete, or with a combination of both variants. The great number of applications of our products and the great variety of versions allow for new approaches, even with solutions which go beyond conventional procedures.
Application in Core Slabs (Building Shell Pipes)
Hydra displacement pipes (hollow elements) can also be used in the construction of commercial or industrial buildings because of their harmonized dimension ranges when it comes to constructing modern and slender buildings
Application in Bridge Construction
The application of pipes made by wbr as hollow parts in bridges allow for savings in reinforcement steel and concrete. This will result in a considerable weight reduction. The „more slender“ buildings made in this way will integrate themselves better into the landscape and thus require less interference. In this way, Hydra displacement pipes allow for economical building not only in the foundation of a bridge but also in the structure itself.
