Grafstal road bridge

 

Solutions & Technologies

The concrete of the abutments and central pillars of the Grafstal road bridge (municipality of Lindau) above the A1 motorway showed damage due to chloride infiltration.

 

Description

Instead of pouring a traditional concrete, the owner of Grafstal bridge opted for a coating of Ductal® Infrastructure. The layer, which is only 40mm thick, is completely waterproof and crack-free and reduces the size of the structure. In addition, the installation was simple and the Ductal® solution could be applied in a single step despite the height of up to 3.3 m.
