Von den Entwurfsgrundsätzen für Tiefgaragen-Bodenplatten zur dauerhaften Ausführung

From the design principles for RC-ground slabs in underground car parks to the durable execution

Planning of underground floor slabs, special attention must be paid on the durability of the construction as a result of the severe chloride exposure. This durability has to be ensured by a thick concrete cover with a chloride dense concrete or by the application of a surface protection system. Further measures have to be taken to prevent chlorides to penetrate into cracks. These measures are specified within the existing rules and regulations. In the design of new DBV Guide to Good Practise, Design Principles are provided, from which construction alternatives can be derived. For the implementation of the Design Principles at the construction of underground floor slabs three examples are given.
