| Abstract: | Watertight Concrete. About Planning and Execution The use of watertight concrete is regulated by the DAfStb‐Guideline. In practice this means that concrete buildings have to be erected as watertight structures. This method avoids the high costs of a bituminous sealing. It requires a clear predefinition of the use of the rooms, in order to define — on the basis of load and exposure — the concrete grade, arrangement of reinforcement, joint finishing, progress of concrete placement and seasoning. A proper structure can only be achieved, if the individual steps of the „quality assurance chain”︁ are dealed with continuously. Drying of the concrete and vapour diffusion should be taken into account for the later use. |
