Protan Vacuum System
Protan vacuum roof is a unique system which does not require fasteners on the roof surface. The membrane is laid loosely on the roof and sealed tightly around the perimeters and penetrations. This system uses wind pressures to create a vacuum effect which secures the membrane to the roof structure.

what if I want a clean concrete finish on a flat roof to use for recreation? Can I pour concrete on top of it or how is it done?

If you use concrete, you dont need vacum system. Concrete is ballast.

Just use type G membram between. Without fastenings, just weld it together then pour concrate on top but u have use some delatating membram beetwin. Chemical reactions will eat membram. For this case asphalt is better
