The spectrum of application of the blind area during construction is quite wide, it is used in the construction of residential, production, trade and other facilities. It is used to take water from the foundation, which allows you to protect it from its harmful influence. The dictionary distinguishes two words that consists of this term: to bridge-cover with something, to get off-to do something to the descent of something. Such a definition helps to conclude that the blind area is an artificially created strip connected to the foundation or base, as a rule, has a width of 0, 6 – 1, 2 m. They usually make a bias of 10 degrees, which is sufficient for the water to be removed to the side.
Before laying the blind area around the house with your own hands, you should take into account the wishes to the decorative appearance, determine the width, angle of inclination, composition of layers and other parameters. In this case, it is necessary to take into account the geological conditions, the planning of the structure and the device of drains from the roof. The coating itself, which is visible outside, can be made of any material and depends only on your preferences.
Types of blind area
Basically, during the construction in summer cottages, the blind area is made of mint of clay having a thickness of 10-15 cm, which
put thoroughly on the initial surface. The properties of clay do not allow to pass moisture, which is assigned to
The right place. When installing such a blind area, various material can be used as a coating on the outside.
The economical version of the blind area can be made from gravel, which must be carefully compacted. If the structure does not have a drain organized in several places, then such a blind area will have to be regularly restored due to falling water, which will violate the structure of gravel.
The highest quality blind area will come out if a cement solution is laid on a layer of gravel. This design will require large financial costs than the previous one, but will allow you to well protect the foundation from moisture, in addition, it does not require constant care and correction.
For those who are used to doing everything, a blind area from a monolith slab is ideal. In this case, you will have to fill the plate with a thickness of 6 to 8 cm, which will serve as a blind area. This option should not be used if the structure is located on soils with a lot of water and clay. Very often, builders of the moment are missing from the calculations and as a result the owner often has to close cracks in such a blind area.
At the moment, it is popular to make a blind area from a solution of cement and sand, with which reinforced slabs are created. This design can be easily made independently.
How to make a blind area around the house with your own hands
It is best to make stoves from cement and sand in size 60×60 cm and 3 cm high. First, the formwork of the desired height should be built. The walls of the formwork join each other so that then they can be disassembled and used in another place.
For the maximum quality of the blind area, the slabs will have to be strengthened with reinforcement. To do this, you need a metal frame that will give strength even with such a small thickness. The reinforcement will also minimize costs and save cement. It is best to use a grid with 8 cm cells as a reinforcement. A smaller diameter allows you to give more strength. In the absence of a grid, you can use cans from which you need to pre-chop bands of 8-10 mm and combine in a single design. Steel wire is also suitable, it should first be cleaned from oil and isolation material, as well as burn.
So, we have a formwork, now you can start making the plates themselves. At the base, we spread a film made of polyethylene so that there are as few folds as possible, which will allow you to better divert the liquid. The solution is prepared and poured 2/3 from the entire height, the metal mesh is installed and the solution is poured again.
To accelerate the setting, you can recommend put a piece of burlap or torn grass on the tile. Such plates dry for 3-4 days, after which you can safely remove the formwork.
Reinforced slabs as a blind area
Reinforced slabs made from a mixture of cement and sand are the most effective way to protect the foundation of the structure, especially in cases where the structure does not have an organized gutters as a result of which promotions are formed on a regular blind area. Reinforced plates are much more stable to such influences, they will not have to be constantly looked after, but they need regular shift with a U -turn by 90 degrees.
Such plates can be made colorful by adding a dye to a solution, which makes them quite attractive.
You can come up with other options. For example, you can lay out a blind area around the house with your own hands with ordinary paving slabs, which looks good and durable. Thanks to these qualities of tiles, it is increasingly used in modern construction to create such structures.
In the manufacture of the blind area, various factors must be taken into account, from existing finances to the features of the site on which the structure is located.
