In the complex dynamics of interaction between the elements of the construction of a private house, the stage plays an important role. Antediluvian clay and asphalt-concrete structures of the blind area have long been in the past, giving way to blinds from paving slabs and clinker. How to set the blind in a country house?

Blind area as an element of improvement
A significant element of the improvement of a private house is the blind area, which gives the building or structure a complete view.
Practically the blind area is erected after the end of the construction of the house or cottage and the finishing of the facade and the socle. The main function and purpose of the blind area of a private house is to divert water from the foundation and walls of the structure. Private houses, equipped with a blind, always looks attractive.
According to the current regulatory documents regarding the device of the blind area, it is said:
• the blind area is erected continuously along the perimeter of the building and must have a preparatory layer from the local soil of the sealing, the thickness of which is not less than 15 cm.
• the width of the blind area of a private house should not be less than the width of the roof projection
• the blind area is made with a slope towards the ground, ensuring the drainage of water. The minimum percentage of slope should be 1.5-2.
• it is necessary to provide a technological gap between the wall of the house and the blind in the form of a compensating weld up to 2 cm thick with filling it with sand.
Thus, based on regulatory documents, you can solve the problem: "How to properly make a blind area at home."
Types of blind area
It is necessary to distinguish such types of blind area:
• Classic
• monolithic.
For the classical type of blind area is characteristic of its solid device along the perimeter of the house from the outside. This type of blind area can be located close to the base of the building. The width of the blind for this type is 80 cm, the angle of inclination is in the range from 5 to 10 degrees. The classic look should be wider in width than the protruding part of the roof at 20 cm. The classic look of the blind area looks like this.
For a monolithic type of blind area is characterized by a massive and high-quality execution of a concrete solution. As a basis for monolithic blind area use the compacted sand of the middle fraction, covered in prepared trenches.
Technologically, the blind area of any type consists of two different types of layers: the cover and the underlying layer.
Therefore, the device of the blind area of the house is made in stages and depends on the type of the underlying layer. What experts recommend to know about the device otmostki specialists, shown in this video.
How to make a blind area with your own hands
blind area of crushed stone
Crushed stone can be confidently called the simplest and cheapest way. Blind area of crushed stone is an ideal option with a significant level of groundwater in the house. When using a blind area, crushed stone is used in the fraction 8-32 mm. The device of the blind area of crushed stone is as follows. The continental soil along the perimeter of the house is compacted, then the membrane from the geotextile is laid.
Without additional implementation of backfilling with sand, geotextiles are poured with rubble with a layer thickness of 10 cm and the blind area around the house is almost ready!
For your information: one square meter of blind area from rubble can be done in 25 minutes.
asphaltic concrete
Asphalt concrete pavement near a private house is rarely found today. The laboriousness of the step-by-step process does not justify the final result, because the asphalt pavement after a while becomes unfit for use and begins to crack.
Blinds of this type can be found only near the high-rise buildings of urban houses, reminiscent of a long road in the dunes of the Soviet period with a half-scratched inscription "Dembel 87". Therefore, asphalt concrete blinders are rarely dealt with.
concrete area
Concrete blind area is also the most popular type, which you can build yourself. Its construction begins with the marking of the field. The recommended width should be 700 mm, sometimes even more.
After marking the field, it is necessary to remove the soil to a depth of 25 cm. Then the formwork is built. Now the organization of the underlying layer is made. At the bottom of the blind area after the selected soil, a layer of sand up to 10 cm thick is laid, then compacted with hand tamper. Especially carefully it is necessary to compact the areas located near the foundation, the sinuses of which are subject to considerable draft. Now the sand is poured with water until it gets wet. Then a layer of rubble, up to 6 cm thick, is laid on the sand layer. For weak and blotting soils, before reinforcing the concrete, the layer is reinforced with a fine mesh net.
The final layer when erecting a concrete blind is the casting layer of concrete. It is desirable to choose concrete class not lower than B-15 height 7 mm. The slope of the concrete area is made depending on the width of 2 percent or 20 mm per 1 m of width. When equipping the blind area of a large area, it is necessary to think about the continuity of delivery and pouring a freshly prepared mortar of concrete. Thus, it is possible to achieve monolithic construction. In addition, it is necessary to ensure the creation of deformation seams in the corners of the building and the length of the wall.
For this purpose, use narrow wooden slats or vinyl tapes. To give the formwork strength, the wet mortar of concrete is covered with a small layer of cement and mashed by hand with a special grout.
More detailed information on the step-by-step device of the blind area of concrete with their own hands is shown here.
For the device 1 square meter of concrete blind area it will take 30-40 minutes of time, taking into account the erection of wooden formwork and the preparation of concrete mortar in place.
To give the concrete area an attractive appearance it is decorated with tiles paving or natural stone.
pavement from paving slabs, pavers and clinker
The most aesthetic solution of the blind area is its arrangement of paving slabs, pavers and clinker.
Sidewalk tiles, as well as pavers, are laid on a carefully prepared layer of crushed stone or sand, whose thickness is 5 cm. It is desirable to calculate the laying tile or pavers from using whole tiles without pruning.
After laying the tiles, the joints between individual elements are filled, followed by a ramming. The final stage of the device blind area of the tile is the erection of a curb. Paving of the blind area of this type is an art work that should not be limited in time. What attracts the blind area of tile paving?
This is a wealth and variety of colors and textures of the finishing material, as well as the geometric dimensions of individual tiles and pavers.
The design of the blind area from paving slabs or clinker allows to conveniently arrange and install elements of drains.
Harmoniously fitting into the overall interior of the socle, the blind area from the clinker with a well-chosen pattern looks great and performs excellently the functions of water removal from the basement and the base of the private house.
However, for laying the blind area of clinker and paving slabs special skills and techniques of work will be required.
For reference: the time of the device 1 square meter of blind area from the paving slab or pavers will be 1 hour, in case you independently produce tile laying.
