The durability of the foundation is affected by its protection against adverse conditions. One such protection measures is waterproofing. Protection of the basis of the building from the effects of moisture and atmospheric precipitation on it is called waterproofing. Since the soil has the movement of groundwater, it is necessary to choose the right materials for this process and perform it qualitatively. The protection measures are called waterproofing work.
Varieties of waterproofing according to the type of product used:
Plastering waterproofing of the foundation is very common in construction. It is convenient and easy to perform, and it is suitable for almost all surfaces. The process itself occurs by plastering the surface with a special composition, which includes mineral additives, astringent components and other fillers. The finished product has a smooth, hard surface about 2 cm thick. In addition, it has a number of advantages, such as the possibility of applying on uneven surfaces, is suitable in the future for any finishing, has good water -repellent properties.
The sprayed waterproofing of the foundation occurs by spraying special compositions to the surface. Its advantages are its fire resistance, lack of smell and seams.
The painting appearance includes many layers of a special waterproofing composition reaching 5 mm. The advantage of this method of protection is that in the solution there are substances that protect metal structures from corrosion, this has a beneficial effect on the use of it for reinforced concrete structures.
The proprietary type is used mainly for porous and cellular structures. This is caused by the composition of the composition into the microcracks of the foundation and their sealing.
The waterproofing of the foundation by inname materials is carried out using roll products. Bitumen mastic is taken as their basis. Bloody waterproofing of the foundation does not cause difficulties when laying roll material, which is a significant advantage.
The waterproofing of the foundation is rarely used in a backfill method, but is not inferior to its qualities. In the role of filler, concrete is poured into the prepared formwork, which perfectly confronts the penetration of water.
Varieties of roll materials for waterproofing
Roll waterproofing of the foundation
Ruberoid is the most commonly used among roller waterproofers, although it has both its advantages and obvious disadvantages. The structure of roller waterproofing resembles roofing cardboard, which was saturated with bitumen. Ruberoid is often used in private houses and garages as waterproofing material, since it is widely available and has a simple technology for applying. It is simply glued to the foundation using bitumen. Among the important shortcomings, one can distinguish the fact that the rooferoid has an organic basis that is prone to decay in case of multiplication of microorganisms. So over time, he loses his properties and becomes fragile.
Asbestos cardboard (waterproof) is widely used in the waterproofing of industrial premises, as well as underground buildings and pipes. Such rolled waterproofing is used for lining the basement rooms of multi -storey buildings. Unlike roofing material, it is less prone to decay and has high water resistance. The waterproof belongs to cheap and durable materials that are used even in regions with low climatic temperatures.
Permamine has been used as protection against moisture penetration for many decades, and there are reasons for this. It, like rolled waterproofing, is a roofing cardboard filled with soft bitumen. Permamine is able to create a waterproof layer and protect wooden structures from high humidity. It is also used to warm window openings or frames. Permamine is most often used in multi -layer structures, especially in summer cottages, but for external work it is not suitable. It does not differ in strength and elasticity, over time it begins to lose hygroscopicity. But low price and wide availability make Pergamin indispensable in the construction of household premises.
In general, rolled materials remain the most affordable and widely used way to protect the foundation from moisture penetration, despite the existing shortcomings. Such waterproofing is simple in mounting, economical in price, universal, as it is used for the structure of both residential and non -residential premises. However, using rolled waterproofing, it should be remembered that the material used for these purposes does not have high technical indicators and after a certain time loses hygroscopicity.
Roll waterproofing techno -nicol for the foundation
Choosing rolled waterproofing materials, very often the user’s choice lies towards products from the company Technonikol. Such popularity was obtained due to the high efficiency of the material and its simple laying during the waterproofing of the foundation. “Technonikol” is profitable to use to create high -quality protection against moisture.
Rolled waterproofing for the foundation is a kind of barrier that consists of one layer of bitumen and the second layer of bitumen-polymer composition. Fiberglass, polyester or glass chloride is used as the basis. They have high strength and are resistant to microorganisms. Such properties improve protection against moisture penetration and increase the durability of waterproofing.
Horizontal and vertical roll waterproofing
Distinguish horizontal and vertical waterproofing. The first isolation is responsible for protecting the foundation of the already built house on its horizontal plane, on which the walls of the building are then erected, and the second protects the vertical surface, which is located under and above the ground.
If the waterproofing of the foundation with roll materials is carried out in a horizontal direction, then the selected roll insulation is laid on the tape on top, capturing the first floor of the connection along with the foundation. If there is a basement or a basement compartment in the construction, then the basement and the foundation together should be laid out with insulating material.
When the mounting of the waterproofing material is located vertically, the material should be fixed to the base of the wall.
And in vertical and horizontal isolation, roofing material is used, which has a different look, starting with the elasticity of the material, ending with resistance to various climatic. The price of this material depends on its practicality and long -term operation. It is worth considering that the roofing material with the basis of cardboard is not reliable for such isolation. A great option in choosing can be roofing material that is based on polyesterol fiber, such as roller materials from Technonikol’s company . A type of glassproof roofing ground can be laid in one layer, this will be enough to ensure good waterproofing. However, waterproofing materials that are used for any types of flat surfaces can be used as waterproofing.
The profiled type of membranes can only be used for waterproofing in an upright position. Rolled materials have a self -adhesive surface, but some can not be fixed without the use of welding. For the installation of such membranes, an additional material is a bar and tape. For flat waterproofing of the foundation, the ideal option would be bitumen mastic. However, before applying this material, the surface of the walls of brick is plastered with a cement mortar.
