Having completed the construction of a house, many people ask a reasonable question: from what and how best to build a high-quality blind area around a fresh building? This process needs to be given special attention. In this article we will tell you exactly what the blind area is for, and what it is.

What it is?

Before understanding the purpose and distinctive characteristics of the blind area around the house, it makes sense to answer the main question - what is it? A blind area is called a waterproof coating mounted around the perimeter of a built building . It can be a concrete or asphalt strip. It continues along the entire structure. In this case, the necessary slope is necessarily made in the direction of the building.

The blind area needs to be equipped, regardless of what foundation the building has . It can be erected on piles, strip or any other foundation.

Installation of such an important component as a blind area is a prerequisite that cannot be neglected in any case.

Significance for protection against groundwater and melt water

One of the most important functions of the structure in question, equipped in the environment of the house, is protective. This functional addition effectively protects the foundation foundation of the dwelling from destructive penetration of moisture, as well as freezing and possible swelling . These are very important tasks. The durability of the entire structure directly depends on their solution. It is for this reason that protection must be reliable and of high quality.

So, for soils characterized by a high occurrence of groundwater, high-quality waterproofing of the prepared blind area is a prerequisite . In the above situation, one clay layer will not save money. Only modern high quality waterproofing coatings can come to the rescue. The upper layer of the blind area can also be constructed from crushed stone. In this case, the concrete base will be able to guarantee 100% reliable protection of the foundation against water penetration. No other building material or mortar can guarantee the same good protection. True, the rigid blind area also has its drawbacks.

Decorative function

The aesthetic function, for which the blind area around the residential building is responsible, cannot be underestimated . Buildings always look more attractive and complete in terms of design when complemented by the structures in question. Moreover, there is no need to use exclusively concrete mortar or gravel. It is quite possible to use a wide variety of materials. Many homeowners prefer to resort to various interesting design options for the blind area, so that the appearance of their home is even more spectacular and original.

When decorating the blind area, you can use materials of different colors and textures. The very form of this component in the environment of the dwelling can be not only standard, but also round, wavy and any other.

Blind areas made in this way always attract a lot of attention. With their help, you can literally transform the appearance of the building, protecting it at the same time from water penetration.

Importance for thermal insulation

It is worth noting the important thermal insulation function of the blind area, which is built around the houses. Many people are aware that temperature changes can have a great detrimental effect on the foundation. Because of this, the strength reserve of such structures is noticeably reduced, which will certainly lead to the gradual destruction of their main elements.

In such situations, a "scarf" in the form of a properly erected blind area may be the salvation for the foundation . This component will be able to form the necessary heat, which will level out sharp jumps in temperature indicators. If it is planned to equip functional rooms like a gym or a billiard room in the basement or on the territory of the basement, then the device of the blind area must be thought out in advance and taken with full responsibility. Only in this way it will be possible to effectively and without negative consequences retain heat in such spaces.

Preventing soil heaving function

As you can see, the blind area serves as a very important and functional component that perfectly copes with many tasks that are important for houses. That is why many people complement their residential buildings with similar designs. In addition, the blind area is able to effectively prevent possible swelling of the soil in the area. This function should also be considered very important and significant for any buildings.

A mandatory requirement for buildings erected on sandy, heaving and moving soils is the presence of a well-built blind area . The indicator of the level of its occurrence in such conditions should be at least 30 cm. In addition, it is required to use a reliable reinforcing layer. Its construction must also be implemented in accordance with all the rules and regulations.

Varieties of blind area, their pros and cons

The blind area can be arranged using a variety of materials. Each of the options has certain pros and cons. Based on the specific type of structure, the structure under consideration can be rigid, with a fixed base, and also consisting of separate components. Let's take a look at the main strengths and weaknesses of the various options.

Concrete

The most uncomplicated, inexpensive blind area, characterized by an extremely simple design. It is very easy to build. This requires only formwork, which, if necessary, is reinforced. Subsequently, it is poured with a concrete solution.

The main advantages of a concrete blind area are as follows:

• such designs have an affordable cost;
• durable;
• effective and functional;
• simply assembled and repaired.

Of the minuses, the following can be noted:

• not the most spectacular view;
• the need for repair work when cracking occurs;
• it is necessary to prepare the formwork;
• extra time is required for the formwork to freeze;
• the installation work itself turns out to be much more laborious.

From rubble and gravel

This option is related to the category of soft blind area. It is most often mounted on heaving and moving soils. Thus, excellent performance of the structure is ensured, as well as a long service life.

The most important advantages of such a blind area are associated with the following parameters:

• they are made from available materials;
• they are built quite quickly and easily;
• it is not necessary to additionally provide for special expansion and expansion joints;
• similar specimens look more aesthetically pleasing and attractive.

The main disadvantage of the considered blind area is that it turns out to be less resistant to mechanical damage than its concrete counterpart.

With decorative trim

To get a beautiful lining of the built blind area, you can use a variety of materials. It can be paving stones, paving slabs, porcelain stoneware, pebbles and other similar options. Each of these options requires the use of a specific styling technique.

For example, a very aesthetic paving stone in most situations is mounted on a soft type of blind area with the equipment of a clay castle. But such a popular coating as porcelain stoneware should be laid out on a concrete solution that has not yet hardened.

Such decorative options for the blind area give the house a much more spectacular and neat appearance, but often require a lot of money.
