Starting to build their own country house, all people dream that he will serve them faithfully for more than a dozen years. However, in order for your cottage not to require constant repairs, you should carefully plan the construction work, not forgetting about even one, even the most insignificant element. Therefore, the question of how to make a blind area around the house correctly excites many. After all, this inconspicuous element is responsible for protecting the foundation from precipitation, thereby preventing its destruction.
Why do you need a blind area around the house?
In places where heavy precipitation often occurs, a periodic increase in groundwater is noted, which, rising, can harm the foundation and erode adjacent parts of the soil. Because of this, cracks can appear in the walls and foundation of the building. You can not build houses without a blind area on heaving soil. The fact is that in this case in winter the soil can be very saturated with water and freeze, as a result of which the uneven distribution of icy soil and its pressure affect the entire structure. Therefore, when building a building on heaving soil, the blind area is recommended to be carefully insulated.
How to blind around the house: design features
This protective structure consists of two elements - the underlying layer and the coating. The first part is needed in order to create a dense and even base for subsequent laying of the coating. Fine crushed stone, clay, sand, etc. are used to create the covering part. Experts recommend the use of clay coating, since it has the best level of waterproofing. The thickness of the coating layer must be at least 15 centimeters.
It is best if the blind area will surround the entire building along the perimeter, tightly fitting to the base. And the larger its width, the better the water will drain.
To think about how to make a blind area around the house, it is necessary already at the stage of construction of the foundation. True, some masters argue that it is better not to create a protective structure at the same time as the foundation, since after the construction is completed, the soil can settle and voids appear in it, which will lead to cracks in the area. However, if work is carried out in compliance with all technologies, such incidents can be avoided.
The blind area around the house, a photo of the process of the device which can be seen in numerous building editions, is divided into several types. Allocate brick, cobblestone, soil, asphalt and blind area from concrete slabs.
Concrete blind area is the most popular type in the capricious climate of our country. However, if the structure is made entirely of concrete, it may collapse at the first frost. But how to blind around the house correctly? When arranging this type of blind area, concrete is laid with wooden slats or reinforcing mesh. Also, the protective structure must be properly insulated, this is especially important if the house has a basement or ground floor. As materials for waterproofing, roofing material, a plastic film or a PVC film are used to organize water bodies.
