Principle:
FDC 01 uses a simple physical effect of pressure difference. Liquid tends to enter the sewer through its openings but also through looseness at the edge of the sewer. In order to prevent it, it is necessary to place a barrier there which is also safely sealed. A thin, highly flexible foil which is exposed to hydrostatic pressure thus creating perfect adhesion to even irregular surfaces and edges has shown the best results. For this purpose we have chosen highly chemically resistant, flexible and strong foil which we attached to a flexible and magnetic foil with openings; this is how we allowed the liquid access to the bottom PUR foil.
Testing:
We subjected the results of development to multiple tests on a special tester imitating real conditions of deployment. On top of that, we also entrusted professional fire brigades with verifying the efficiency
