High humidity in living rooms in recent decades - the subject of attention of health authorities in European countries. Traditionally, priority in construction have always been a problem the thermal protection and soundproofing. The energy crisis of 70 years in Germany led to the development of systems of insulating windows as one of the areas of energy saving technologies. Consequence of the innovations was the reduction in the functions of natural ventilation and increased humidity indoors. High humidity in the room - the reason for the appearance of putrefaction, breeding colonies of fungi. Dangerous, in fact, not the mold, but millions of spores, which inhabit the air and fall into the respiratory system and circulatory system. Particularly sensitive to these children, the elderly, people with weakened immune systems and are prone to allergic diseases. This, above all, respiratory diseases, including bronchopulmonary this skin disease and musculoskeletal system. High humidity is typical for underground spaces: basements, especially basements. The damaging effects of water on the structure of brick and concrete - a fact well known, because these materials have branched capillary-porous structure. Penetrating into buildings groundwater reduces the carrying capacity of concrete and bricks through leaching of free lime and the processes of freezing and thawing. In addition, ground water contains impurities salts: chlorides, sulfates and hydrocarbons. Crystallizing and gidratiruyas in the pores of salt many times increase in volume, which leads eventually to the destruction of the material of bearing elements, contributes to the strain of finishing coatings. Precipitation in the industrial centers contain impurities acids (due to industrial emissions of acidic gases), as well as excess carbon dioxide, therefore, in addition to freezing the action, destroy the chemical structure of concrete and marble. The problem of protecting material from water and moisture is solved in different ways waterproofing and water-repellency (water repellency). Some practical advice Waterproofing 1. Preferably, the use of modern materials and technologies that provide comprehensive protection from water. This outer waterproofing basements obmazochnymi bitumen-polymer compositions, it is an internal waterproofing basements and caps obmazochnymi cement and polymer-cement pastes, Protects against the external (negative) pressure of water. 2. Requires careful study of "highly dangerous" areas: the corners, seams, joints contiguity of different designs. In places the coupling of different surfaces should be taken into account the increased danger of cracking. Joints and seams are in need of a multilayer flexible protection. This is a fillet of non-shrink material or elastifitsirovannogo cement-sand mortar followed by treatment with an elastic waterproofing. This may be a multi-layered elastic tape, "sunken" between layers of flexible waterproofing. 3. Protection of the deformation and construction joints - a separate issue. There are various options for waterproofing seams: sealant (polyurethane and tiokolovye), elastic tape, elastic wedges, swellable tape, swelling paste and injectable hoses. The possibility of using each of these options is considered on an individual basis, depending on the nature of the design or construction, and their status on the operating conditions, as well as the intensity of the mechanical and the degree of aggression of water stress. 4. Places contiguity fixtures (pipes, tubes, etc.) as well as the seams, posing an increased danger because the water often finds a way it is in these problem areas. Heterogeneity of materials: concrete, metal, plastic, concrete requires the selection of individual primers for the corresponding surface, and the application running sealant. Polyurethane sealant provides an opportunity for such protection in both positive and negative water pressure. 5. Application of finishing vapor-permeable materials (plaster, paint) will help to avoid dampening walls in the condensation of steam. 6. To guarantee positive results, we recommend the use of complex materials by the same manufacturer. Hydrophobicity term does not adequately waterproofing, as repellent surfaces are not experiencing water pressure, ie facades of buildings. Most of the facades, especially of brick, hit by water-soluble salts, primarily sulfates, contributing to the destruction of the material. Therefore, the brick needs to be cleaned of salts and subsequent water-repellency. This may be: 1. Flyuatirovanie - conversion of water-soluble salts, sparingly using a special fluid with subsequent mechanical cleaning of the reaction products and plastering light vapor permeable, hydrophobic plasters, preserving the facade of the freezing and destruction. 2. The method of cleaning with a dilute solution of salts of weak organic acid. The liquid is applied on saline land, the reaction products were carefully removed by the mechanical (brush, a coarse cloth). Acid solution opens up the surface pores, and therefore more necessary to make hydrophobization - impregnation of organosilicon compounds. 3. Repellent liquid is a composition kremniiyorganicheskuyu silane-siloxane type in an organic solvent, to ensure sufficient penetration rate of molecules in the capillaries and pores and a high rate of cure. Under the influence of carbon dioxide and moisture in the air a thin waterproof but vapor permeable film that effectively protect the facade from the weather. If the humidity in the rooms already bore fruit, and on the inner surfaces of the walls there was mold, it is necessary to take urgent measures to eliminate it, and at the level of microorganisms (spores). These properties biocidal liquid, successfully cope with the problem of mold fungi on mineral surfaces. It should be noted that as individual protective measures, and the complex measures for waterproofing and repellent plants extend their lives and preserve our health.
