In addition to all of these advantages, perhaps the most important feature of using disposable formworks in landscape areas is that the reinforced concrete structure constructed with disposable formworks will not prevent the flow of drainage water. Technically, in such a podium area, the drainage water flow direction and the floor gutters should be planned very carefully. Ideally, all slopes, regardless of the structures on the area, should be adjusted in an architecturally appropriate way to the large main structure.
The most standard layers that we encounter in our experience are as follows; first of all, there is the slope concrete on top of the structural slab, then water insulation comes on top of that slope concrete. Then a layer of vapor barrier and heat insulation of hard polyurethane foam. Finally, a 5 cm top protective concrete layer covers them all. Again, this is a typical section we encounter most often, there could be others. Once the protective layer is finished than bubbled drainage sheets are placed on top of it and then finally comes soil for the plants. Disposable formworks are also placed on the top of the protective layer just like the drainage sheets.
