Insulated blind area is a necessary condition for building a house, since only in this case it is possible to achieve maximum protection of the base around the house from various external influences.
It is the blind area that allows not only to improve the quality of the house, but also to increase its durability.
It is important not only to correctly do it, but also to wisely insulate, using for this purpose only high-quality and effective materials.
The blind area around the house is made for different types of foundations, including shallow ones.
The scheme of thermal insulation can be different, but in any case it is necessary to achieve maximum protection of the foundation and walls of the house.
For paving tiles, which serves as a blind area around the house, you also need to think about how to properly perform insulation.
In order for all the work to be done correctly and in accordance with the technology, a step-by-step instruction is developed.
The technology of work execution, as well as the scheme of warming of the blind area around the house are quite simple and do not require professional skills, and therefore you can do everything yourself, without resorting to the services of qualified builders.

Nuances of thermal insulation of the blind area
In general, the blind area is a strip of a certain width that passes around the house along its entire perimeter.
It can be made using paving slabs, strips of concrete, or some other similar materials.
An obligatory condition for its implementation, both for shallow and for other type of foundation, is quality insulation.
This allows you to maximally protect the foundation of the structure from moisture and exposure to low temperatures, which can lead to its destruction.
The role of insulation can be a variety of material, but in any case, the technology of its device implies the execution by their own hands of several different layers.
So, it is necessary to make the underlayer, as well as to make the top cover and for this purpose the use of paving slabs is allowed.
Such a pie from different layers will prevent the formation of mold and the destruction of those building materials that were used to build the foundation, as well as the socle.
A variety of materials can be used as insulation under the blind. The maximum protection of the foundation will help foam polyurethane.
This foam is an effective waterproofing agent which, due to its elasticity, is able to fill all the slots, thus ensuring a good seal.
This material should only be laid on a pre-prepared basis and for this it will be necessary to make a special cushion of crushed stone and equip the formwork.

It is allowed to lay paving slabs over polyurethane foam. Also, to warm the blind area with your own hands around the house, you can use the penokleksom.
This material also effectively protects the foundation and socle, and besides, the process and the technology of its laying are so simple that they can be executed by themselves.
Penoplex should cover the entire surface along the perimeter of the house, adjusting the sheets to each other as tightly as possible.
You can also use an ordinary foam, which in its properties is similar to a penokleksom. On top of these materials, paving slabs are allowed.
Performing drainage under the blind area of the
Before proceeding directly to the very warmth of the blind area around the house, it is essential to make the proper drainage by your own hands.
It is especially relevant in the case that around the foundation the soil consists of soft clay, has increased humidity, there is a risk of flooding and so on.
In any case, drainage under the blind does not hurt and will further protect the base of the house.
It should be equipped for any type of foundation, including a shallow one.
First you need to arrange drains and for this you can use ordinary plastic pipes. Further around the house it is necessary to dig a ditch, the depth of which should be up to one meter.
The bottom of the ditch is carefully leveled, while making a slight slope towards the well. Also, the walls of the pit should be strengthened, especially if the soil is soft.
Pre-prepared drains should be tightly wrapped with a special cloth, for example, geotextile. This is done so that land and soil do not get into the holes of the drains.
Further on all the bottom of the pit a pillow in the form of rubble is arranged and carefully packed. After that, along the entire perimeter of the pit, the drains are exposed in a certain sequence.
Then it is necessary to fill them with soil, with special attention paid to compacting the soil along the sides of the drains, and also directly to the will of the very foundation of the house.
After that you can proceed to the device of the next layer of the blind area, which will act as a kind of litter under the heater, thus forming a kind of cake from different layers.
Arrangement of the underlying layer and insulation
The underlayer is a prerequisite for making the insulation of the blind area around the structure.
For its correct implementation, a step-by-step instruction has been developed, following which you can do all the necessary work yourself.
To begin with, you should mark up the territory adjacent to the house. After that, along the entire perimeter of the house, in accordance with the marking, the ground is removed onto the bayonet of the shovel.
Then follows all the bottom of the ditch dug with clay and carefully tamper.
As a waterproofing layer, a construction ruberoid can be used, which spreads over the surface of the pit in several layers with an overlap.
After this, it is absolutely necessary to fill the bottom of the pit with a small layer of sand and spill it with plenty of water, after which it should be densely packed.

Formwork is then formed, which should exactly follow the configuration of the future blind area.
After the formwork is completely formed around the perimeter of the pit, a pillow made of crushed stone is made in its internal space.
Before proceeding with the laying of the insulation, the bottom of the pit is recommended to be treated with bitumen, or other similar composition. Next, the most densely to lay the heater itself.
All joints between them are necessarily sealed. It is better if the insulation material is laid in two layers.
This will increase the protective functions of the blind area and further protect the foundation from the aggressive effects of water and temperature.
Next follows on top of the heater to make a pile of sand with a thickness of at least seven centimeters.
Above the sand is laid and carefully compacted rubble, after which a reinforcing layer is formed from the metal mesh.
Only after this, it is possible to start pouring cement mortar along the entire perimeter of the exposed formwork.
Pour concrete is recommended layer by layer, thus, not forgetting to observe a necessary bias towards the arranged drain under rain waters.
After this it is necessary to give time to the solution so that the solution is well dried and strong, after which it is possible to proceed to the formation of the upper face layer.
Formation of the face layer
After the device of the insulated blind zone has been fully completed and its filling is performed, it is recommended to equip the upper face layer along the entire perimeter.
Of course, the top layer can be left and in this form, however, the performance of the face layer will help not only improve the aesthetic properties of the blind area, but also make it even more protected.
For these purposes, the use of paving slabs, as well as other decorative materials, is allowed. In the event that the use of paving slabs is intended, all gaps between the tile joints must be carefully covered with sand.
It should be noted that it is necessary to arrange the top layer with decorative elements only if there is a certainty that the waterproofing and thermal insulation of the blind are performed correctly and in accordance with the technology.
In general, the use of paving slabs as the face layer is the most popular option and in this case it is allowed to lay it not on a concrete foundation.
Do not save on the insulation of the blind area around the house.
Only high-quality insulation, carried out according to all the rules, will help to protect the foundation as much as possible from moisture and low temperatures, and, accordingly, will increase its strength.
As a heater it is necessary to choose high-quality modern materials that will provide good foundation protection for many years.
The material chosen as a heater should be laid only on the prepared surface of the base, and the insulation sheets should be sealed with each other.

Execution of the upper layer of the blind area will help to protect the insulation from the aggressive external influence, and, accordingly, will prolong its service life.
In the event that all the work on the insulation of the blind area is carried out correctly, the durability and strength of the house will significantly increase.
