Moisture has been and remains the main enemy of building structures . investing
heavily in the construction of real estate, you first need to take care
waterproofing of the foundation, roof, walls , basement and cellar.

Damaging effects can provide not only ground water, precipitation
and atmospheric moisture, and water leakage inside the house, condensation and
others. The strength of water expanding during freezing is enormous. Frozen in the pores
building materials Moisture can rip them from the inside, in the literal
sense. A few cycles of wet and frost cracks may be formed
even in concrete structures. In addition, the penetration of moisture in the concrete
construction can expose reinforcement rapid corrosion that
shortens their life. In general, the negative factors that may
bring a lot of moisture, now let's talk about ways to combat it. Waterproofing
underground part of the building is called - antifiltratsionnoy proofing, and
moisture protection of the visible parts of the building is called the corrosion proofing.
Waterproofing materials are separated by means of complete isolation, creating
gidrobarer and piercing tools that reduce the so-called
capillary conductivity. Further, different waterproofing for flat, plastering,
okleechnoy, obmazochnoy, painting, etc. Each of these has a whole
group of materials differing in origin and principle of isolation. Sheet
tight sealing means finishing metal constructions
or plastic. Basically this type of industrial waterproofing, and for private
the builder is not well suited. By waterproofing sheet also includes roofing
materials of metal or synthetic origin, creating an impenetrable
roofing layer cake. Roll insulation provided by modern
materials, works well with its task and is suitable for private
housing, but requires considerable preparation of the surface.
Unevenness of more than 2-3 mm - are not allowed, in addition, the surface should be
dry. Before gluing or fusing roll surface waterproofing
should be primed with a special bitumen emulsion. To roll waterproofing
also include butyl rubber, and polymer membranes, which can be used
as a roofing material. But the main area of ​​application - Sealing
artificial ponds and pools. Bitumen roll materials can be
successfully used in the device structure of the roof, insulation timber
parts and insulating materials that lose property when wet,
, including under-roof and on the water. The appearance of breathable membranes allow improved
protection of roof and make it more manufacturable. Breathable membranes provide
waterproof, while remaining permeable to air. To protect the foundations
buildings have long used natural gidroizolyator - clay. Create a clay
barrier thickness of 50 cm, enough to effectively cope with the security function
of water. Clay not only creates a waterproof layer, but also clogs
pores of the concrete, preventing thus the moisture inside. More technologically
Isolation is a way - bentonirovanie. Special colloidal clay
having a high sorption properties, and swelling forms a waterproof
gel. Bentonite is concluded between the layers of geotextile, and used for isolation
foundation. In this 2-inch layer of clay is sufficient to create
reliable waterproofing. Produce these products company Cetco (England)
Akzo Nobel (Netherlands) and other manufacturers. Waterproofing barrier
You can also create and with a special plaster, composed of
polimertsementy included. Waterproofing materials such different ecological
cleanliness - they can cover the inside even potable water tanks.
High adhesion and vapor-permeable polymer plaster makes a great
material for interior decoration with high humidity. To her
Disadvantages include the relative instability to mechanical stress,
that can lead to loss of waterproofing properties. The most effective
its physical and mechanical properties are bitumen-polymer and bitumen-rubber
mastic. To increase strength and durability of this type of insulation used
fiberglass or fiberglass. Waterproofing can be applied and in layers, with
Brush or spray. For this purpose suitable polymer
compositions containing vinyl acetate polymers. Bituminous mastics, diluted
solvent to a liquid consistency and are suitable for waterproofing paint
method, but it is necessary to apply several layers intermittently.
There is another very interesting type of waterproofing - penetrating. In
Unlike all the above methods, this type of insulation prevents
corrosion, and is based on the penetration into the stone or concrete substances interacting
with cement minerals. The pores of building materials that are applied
penetrating waterproofing, filled with crystals, formed as a result
a special type of reaction. In this case the strength of brick or concrete is increased by
20%, and water vapor permeability decreased only slightly. Also, the penetrating
waterproofing ability to repair itself, making it one of the most
advanced forms of struggle with the pernicious effects of moisture.
