At construction and repair of objects special attention should be paid them to protection against moisture. Getting into designs, it can become the reason of big destructions. Competently to perform construction jobs and to protect constructions from water, it is necessary to make qualitative waterproofing.
Depending on assignment of design and the nature of influence on it of moisture, different technologies of protection are used. Most of all underground constructions need it. To save the building under construction from underground, rain or melt waters, it is necessary to carry out its waterproofing. These works include protection of walls of the base and protection of plates of the basis. Besides, processing of interblock seams, microcracks and entry points of utilities is obligatory – through them moisture from the earth arrives to designs most of all. That the base for many years was support to all house, it is necessary to use modern waterproofing materials. When choosing covering for basements many factors are considered: proximity of underground waters, nature of use of the basement, feature of soil. So, for waterproofing of walls coating materials, and for basis plates – materials of rolled type are used. If the building not new or not opportunities to replace external waterproofing of the basement, then are carried out internal works with use of special material - thin elastic membranes. For heat preservation in rooms at construction of roof use thermal insulation materials. If not to make waterproofing barrier, then heat from internal space, rising up, gets into heater and forms moisture. At the same time rafters and other wood structures of roof dampen that leads to growth of mold and fungus. To prevent freezing and presenilation of roof, works on waterproofing are performed. Under heater the paroizolyatsionny film which does not miss to it couples from housing keeps within. Over it the diffusive membrane protecting roof thermal insulation from penetration of atmospheric moisture is mounted. The waterproofing is necessary not only for garret designs. Such atmospheric phenomena as sleet, rain with the wind or low subzero temperatures cause emergence of condensate on covering of buildings. If at wall construction the thermal insulation material was used, it is necessary to provide also mounting of waterproofing courses. The bathroom is room of the increased humidity. To avoid unexpected leakages of water on the first floor, it is necessary to take care of floor waterproofing. For this purpose it is possible to use material of rolled type on the basis of polymers or bitumen. Also the painting and coating method is applied. In the first case use varnish, in the second – mastic. At construction and repair of pools special attention is paid to internal and external waterproofing. To avoid course of concrete bowl of the pool, apply special membrane on its inside face – polymer cement mix. It in the hardened state keeps elasticity and prevents emergence of cracks from big water pressure. If the pool is only under construction, then the substances providing waterproofing material properties are added to concrete mix for bowl. Special attention is paid to isolation of seams, joints, places of contact with ladders and sides. The external waterproofing is applied that underground waters could not filter through concrete in bowl. Apply modern material to this mounting - membranes of rolled type. Natural desire of the person – to live in comfortable conditions. Even small surplus of water can create big problems therefore the waterproofing is so important and necessary.
