The blind area around the house: step-by-step instructions on how to place it correctly in modern construction (110 photos)
The whole structure of the house is important, it includes many details that create integrity and fulfill their role. Now we will talk about the final stage of construction of personal housing. The main role in it is given to the correct laying of the protective coating.
If it is done qualitatively, then the foundation together with the soil will receive sufficient protection, and this will allow the use of living space for a long time. The blind area forms the comfort of using housing due to the formation of moisture protection, which without it could seep to the foundation and harm its stability.
Because of this, it is very important to know how to blind around the house correctly so that it will serve for many years. Its role is considered paramount, since moisture can significantly erode the foundation, and lead to the destruction of any structure.
The value of such a finish increases if a shallow foundation is used for the building. Water is able to inflict more damage to it, reaching the sole faster, but with the help of a high-quality blind area - this becomes impossible, and the house remains strong always.
If the sole becomes wet for some reason, the structure will begin to sag noticeably. In the case of the use of deep immersion of the sole of the foundation, she will also need a barrier to the penetration of water. It must be mounted in any case, regardless of the reliability of the foundation, the type of soil and other related conditions.
Check out the reliable views through photo blind areas around the house, made by professionals for various projects. They show many approaches to the styling process, suitable for the ideas of architects, designers, taking into account the chosen style of the house.
There is no clear-cut framework for arranging a rockery - a picturesque mess is also possible, close to the natural mountain alpine landscape, flat rocky gravel paths of colored gravel or pebble, intricately laid, are also appropriate.
Stones for rockery will suit any that you find in your area - from large boulders, cobblestones, to medium and, finally, fine grafting.
Granite, limestone, wild stone are suitable, the weathered stone looks very picturesque.
You can entrust the creation of a rockery on your site to a landscape designer, or you can create it with your own hands based on your tastes and preferences.

Why add it to your home project?
It is important to remember that the correct blind area will help protect the structure from serious problems during the operation of the owners. The first thing you need to do is select the right material for your installation goals. In order for its properties to be most useful, you need to choose the correct width of the tiles that form its area.
Experts do not recommend limiting the space for her. If more is obtained, then it is better than less space for its placement. Water will evaporate from its surface or can be absorbed into the earth at a remote distance from the foundation without harming it.
Important: It is recommended to enclose the building with a blind area at least 80 cm from its any edge. Otherwise, it may turn out to be a futile exercise. And do not forget about the decorative possibilities of such a coating. It can be made part of the whole design.
It has another purpose, it is used as paths for passage along the house.It has rained and moisture will accumulate everywhere, and it will help to get to some corners of the cottage in comfortable conditions. This is a very important point because of it it is recommended to take this part of the project seriously and make a blind area on the mind based on a sufficient size.
If it is too narrow, then you have to move along it sideways, which is not particularly pleasant fun for residents. Experts believe that it should reach a size of 1.2-1.5 meters in width. This will open all its functional capabilities and provide sufficient fencing of the foundation from water interference.
What is her device?
It is important to consider the presence of a slope for it, in order to direct water from the walls, and not under them. The builders have calculated that the optimum slope is 50-100 mm for 1 meter wide. But moving around it will not be very convenient, because of this you will have to make a choice - reliable protection or increased cross-country ability.
A compromise size is 15-20 mm for 1 meter of its width. So the water will discharge at a lower speed, but any person will easily pass through the coating.
To decide, it is important to recognize all the nuances, and, to make a suitable device, the blind area around the house for all family members. This will help to prevent the need to rebuild this critical product, forming the proper characteristics of housing outside the city.
And also it is worth adhering to the developed requirements for long-term operation:
- The width cannot be made smaller than the size of the protrusion at the roof, since water will drain further than it, and this will reduce its useful qualities to zero;
- It can not be interrupted and must be carried out around the perimeter of the house;
What will be required to create it?
Turn to professionals and watch how they will do everything in a short period of time. Or make it your own efforts. In the second case, you need to choose the right materials. Various variations of its formation are available, but the blind area made of concrete is recognized as the simplest and highest quality of all popular types. It is not difficult to arrange for any area.
To begin with, the territory is cleared, on which the necessary surface will lie. Then reinforcement is used, its rods are laid on the principle of a grid. They must have a diameter of at least 6 mm to provide the necessary functionality. They are easy to connect with a sufficiently bulky knitting wire.
The time has come for the installation of formwork in the form of long wooden boards. Everything can be done by casting the formwork with a suitable type of concrete.
For the correct implementation of this process, you will have to use a number of tools and materials:
- A shovel is needed to dig holes for the main job;
- The hydraulic level will help to establish the same laying angle throughout the entire area of the house;
- A wheelbarrow will provide a simplified waste removal and delivery of the required amount of crushed stone;
- Manual tampering is required to level uneven places;
- Waterproofing will ensure the reliability of the structure;
- The heater guarantees the durability of the blind area;
- Crushed stone will strengthen it and make it monolithic;
- Clay will connect all its parts into one whole;
- A reinforced mesh based on 10 x 10 cells can replace reinforcing bars.
The main work based on the use of concrete
It consists of the formation of its two layers - for litter and coating. Now we will explain how to fill the blind area without complications with our own hands, taking into account all construction principles.
The underlying or initial layer will help to form a flat surface for the covering level, called the finishing stage. For the first level there is sand, gravel and clay. And on top will be the most important concrete coating.
It is due to this composition that a powerful barrier against water is provided. It is known that it is able to penetrate very deeply, but in this case it will have to drain and pave the other way away from the foundation.
But before this part, it is necessary to remove the soil to a depth of about 20-30 cm around the entire perimeter around the house. Then we begin to compact the base, so that it is ready for another job. If plant roots are found, they can be left alone and not removed.
But, in order to prevent their growth, it is desirable to perform the processing of all processes with the help of herbicides. If they grow, then they will certainly damage the blind area.
We form a removable formwork using wooden boards. We form a layer of clay, and then cover it with sand by about 10 cm. The sand must be compacted using a tamping machine. Then it is slightly watered. The time comes for crushed stone, it is placed 6-8 cm in a dug base.
To reinforce the structure, a reinforced mesh or bars of reinforcement is used. Now a compensation version of the seam is created between the base and the main part of the blind area. A mixture of sand and gravel, roofing material, sealant, a foamed version of the tourniquet is good for this.
Suitable time for pouring the base material. Now the concrete blind area is not yet ready, but is already taking on a completed shape. Before pouring the main solution, it is necessary to lay the slats of wood after every 2 or 3 meters. Before installation, they are treated with a coating against decay.
It is important to monitor the correct bias of their placement. They will help to create the correct form. Then it comes to concrete. You must use a quality type like M 250 or M 300, suitable for various road works.
To make the coating stronger, the ironing method is allowed using a dry or wet approach. It consists in adding another small layer of 2-3 mm on top of the drying concrete.
The first consists of dry concrete, which must be carefully pressed into the main layer by tapping.
The wet version includes a solution of ceresite, water glass, sifted cement and water. Within 7-10 days, the resulting mass will harden. Now the product can be used.
We see that the whole process is quite simple, but takes a lot of time. It is also important to think about a sufficient amount of funds for its full implementation. The total cost of filling the blind area can be impressive, but it will depend on its size and quality.
Naturally, you can reduce it, and use a simplified installation option, which will help to save, but will affect the quality and durability.

The first rule in construction is that you cannot save on the foundation and blind area. If the blind area is not made correctly, then water will flow under it, and in the end it will smear the foundation.First of all, you need to make markings, then it is good to smoothen the earth, then lay the reinforcing mesh and be sure to install expansion joints, and only after these preparatory work can concrete be laid.
Quite often you have to see cracks in the blind area, even among people who hired experienced builders to build it. Now, despite the huge abundance of goods in stores, there are big problems with buying high-quality goods. Very often, cheaper ones are put in bags from cement of one brand, this makes itself felt in winter. The reinforcement gives the blind area additional strength, but will not solve all the problems with concrete quality.
I myself made the usual blind area manually and realized that it would be better to hire builders and lay out paving tiles. He spent a lot of time and effort, but in the end, after three years, the entire blind area cracked and began to crumble. Plus, weeds began to make their way through it. I’m sure of the materials, but to cope, it would seem, with a simple matter did not work.
For a long time we could not decide on the design of the blind area, as we really wanted to combine the external aesthetics with quality and durability. Experts advise to leave as much free space as possible for beautiful masonry, which is what we did. We chose bricks of three shades, thought over the drawing, ordered a drawing. A very beautiful result was obtained, and the workers did well.
Thank you very much for the useful article and good advice. Just closer to summer, we are going to do major repairs at home, but first of all, we need to strengthen the foundation and do the blind area well, because a lot depends on it later. The husband will do it on his own - I will show him an article, let him read it, he will take the necessary information for himself. You are so well shown in the photo)))
Our grandfather built a house in the village and made a blind area of concrete. Over time, most of the residential buildings where there was no such protection, fell into disrepair, and our house is now in perfect order, he even survived his grandfather. The case seems to be not so costly, but what benefit it gives. My husband and I are also completing a house, though in an urban area, and we will certainly put such protection for the foundation.
