SYSTEMS

Cities are becoming ever more densely built and there are more and more cars coming in too. So we must try to use the little space left to us as optimally as we can. One way to realise that is stacked use of space. Examples of this are underground car parks with high-rise office blocks above them, or apartment complexes with mezzanine roof areas with planting and drive-on paving.  That delivers space, but also a better quality of life and a more attractive environment.

Nophadrain parking roof decks provide for optimum utilization of roofs. One prerequisite, however, is that the architect and structural engineer take account in the design of the extra demands placed by installation of this type of roof. 

A parking roof deck does not have a natural substrate. For installation of paving on a roof construction, therefore, the Nophadrain system for parking decks takes account of the following:

• The difference in structural behaviour of the support construction: natural substrate versus roof construction.
• The waterproofing membrane: suitable for static and dynamic loading.
• The roof construction: traditional warm roof, inverted roof, non-insulated roof.
• The pressure-resistance of the thermal insulation.
• The type and layer thickness of the ballast materials: foundation layer, filler layer, paving layer.
• The type of paving.
• The use, and the intensity of it, by people and the loads that creates.
