The thickness of the blind area around the house

A blind area is called a bulk covering around any structure, including a private house. It has two functions: decorative and protective. How long the foundation will last depends on how correctly such a coating is made. Consider what is the thickness of the blind area, and what factors affect this indicator.

The blind area is made around the perimeter of the house. It must protect not only the foundation, but also the basement, the basement from water. It is often decorated with decorative materials and plays the role of a track.

When organizing a blind area, it is important to take into account:

• thickness;

• width;

• tilt angle.

A well-designed blind area becomes a high-quality hydro-barrier that protects the base of the house from rain and melt water. There is an option when it is made quite wide in order to use this space as a recreation area.

The blind area can be of various types, its thickness largely depends on this. In practice, several basic approaches are used to organize the space around the foundation.

It is used most often because concrete has established itself as a practical, reliable and durable material. You can make such a platform yourself if you understand the technology in more detail.

According to the standards, a blind area made of asphalt concrete is used in most cases to protect multi-storey buildings. Has several disadvantages:

• it is difficult to tamp the material on its own;

• when laying asphalt, its temperature should be at 120 degrees.

It is almost impossible to make such a blind area without the use of special equipment.

The material is laid on concrete. Only clinker tiles are used, since only they have the necessary stability.

Among the disadvantages is the high cost, but such a coating does an excellent job with the task at hand.

Not so long ago, it is used to organize a blind area, but the material has already proven itself only from the good side.

It is not often that you see such a blind area, and there are several reasons for this. It is not very convenient to move on such a surface, it constantly crawls and needs to be corrected.

When organizing a blind area around the house, it is imperative to use GOST and SNiP. In this case, take into account:

• GOST 9128-97;

• GOST 7473-94;

• SNiP 2.04.02-84;

• SNiP 2.02.01-83.

This parameter is determined knowing the type of soil, since a different composition affects the degree of subsidence. If it is clay, then there are two types. The first one sags by an average of 5 centimeters. The clay of the second does not sag at all.

For the first type of soil, the width should be at least 70 cm, for the second - at least 100 cm. If the soil is normal, then the value varies from 80 to 100 cm.

And also the overhang of the roof over the walls is taken into account. In any case, the width of the blind area should be 20 cm larger for normal soil and 60 cm larger for clayey soil.

When making a final decision, the following factors are taken into account:

• foundation protection;

• the degree of walking on the blind area of ​​a person or a car.

The minimum allowable thickness of the layers is 7 cm, the best option is 10-15 cm, while the blind area should rise 5 cm or more above the ground. If the coating also plays the role of a footpath, then the requirements for the thickness of the screed will become more stringent. It is advised to pour concrete of a certain brand, increased strength. All attention is paid primarily to the sand cushion.

The recommended slope is made from 1 to 10% in the opposite direction from the wall. For 1 meter wide, this figure is 1-10 cm.
