Product Advantage from wbr
HYDRA cladding pipes facilitate by their special shape the gapless pressurizing of cavities between pre-stressed steel and cladding pipe walls with grout-in mortar. This ensures a permanent corrosion protection for the pre-stressed steel and the necessary joint for force transmission from the pre-stressed member to the cladding pipe, as well as from the cladding pipe to the surrounding concrete.

80,000 m cladding pipes
A new transit expressway line from Brussels to Cologne connects the metropolitan area of Cologne with the French railway net for express trains. For the realization of this project four large bridges had to be erected in the Ardennes, completely made of pre-cast concrete elements. Three plants were busy to produce pre-stressed concrete elements.

Just-in-time
The company wbr has been delivering more than 80,000 m cladding pipes in various types just-in-time, always right on schedule with the construction progress. In order to meet the specific requirements of this project wbr has exclusively manufactured a pipe with special corrugation.
