Abstract: A kit of parts suitable to form a waterproofing membrane consisting of a first component A including or consisting of a) 5-60 mass parts, preferably 30-60 mass parts, more preferably 45-55 mass parts, of a hydraulic binder, b) 0.5-15 mass parts, preferably 1-5 mass parts of at least one synthetic polymer, c) 20-80 mass parts, preferably 30-50 mass parts of aggregates, and d) optionally further additives and a second component B including or consisting of an aqueous emulsion of bitumen.

Abstract: A system (1) for the execution, traceability, monitoring and control of reducing the bacterial count in a confined environment, includes an environment identification device (2) arranged to contain information relating to the confined environment. A device (3) for micronizing air-dispersed decontaminant substances is arranged to diffuse through a diffuser (9) a decontaminant substance (12) by air as dry fog, based on the information contained in the environment identification device (2). A detection sensor (4) detects the concentration of the decontaminant substance (12). An instantaneous bacterial analysis sensor (5) determines the quantitative and qualitative bacterial concentration.
