In the presence of well-functioning heating and ventilating systems, these actions will improve the quality of life and time services newly constructed buildings and facilities. John Mclaughlin may also support this cause. In the case of existing premises, it requires two conditions. The first - the destruction of fungal and bacterial structures within the premises. The second - performance complex construction and repair work on the 'treatment' of buildings. Destruction of fungal and bacterial structures is a water-polymer antiseptic and environmentally safe. To date, developed technologies that allow for a sufficiently low cost to create a sterile surface, followed by protection of up to 15 years from a variety of infections, will not be affected gas exchange material and the environment.
Construction and repair work on the 'treatment' of buildings involves the following areas: 1. Waterproofing basement polymer concrete compositions or other materials. 2. Protect walls, ceilings basement water-repellent compounds. 3.
The elimination of roof leaks. 4. Works on drain walls, elimination of the infiltration process, the preservation of the facades of destruction. Particular attention should be paid to the 4th direction, which is more promising with respect to a particularly old buildings, the historic center, monuments of architecture. In a humid climate is the next process. Humidity due to capillary absorption (typical of the walls of old buildings) leads to the destruction of the plaster coating. It occurs when porous materials are in contact with the soil and absorb groundwater. As a result - damp walls and crumbling plaster. Formed on the surface of masonry efflorescence, and the further flow of moisture from the dissolved salts leads to the growth of crystals and the destruction of the surface, creating optimum conditions for the development of fungi and bacteria. Today, there are systemic materials for integrated application can prevent or effectively deal with the described phenomena without mechanical influence on the wall (which is especially important when restoration of buildings of civic, historical or artistic value).
