Abstract
The text of the paper deals with the unusual use of textile membrane, originally used in outdoor clothing, as hydrobariers in building composites. In the experiment, the resistance of the building composite exposed to the 1.5 m high water column is examined. Research is conducted on two levels. On the first level, we focus on developing a building composite that includes a smart fabric membrane and is waterproof and vapour-permeable. On the second level, we deal with the development of a measuring system which will be able to correctly evaluate the water resistance of the building composite. A moisture-proof and air-permeable membrane can protect construction against various effects of moisture (i.e. flood, rain, ground water). The resulting water permeability values are compared with the four types of construction composite. It is discussed whether it is possible to create hydrobarriers in buildings if a textile nanofibrous membrane is composed into the building composite. If the composite is able to capture 70-80% of the water then the energy savings are significant.
