How to make a blind area around the house yourself
The blind area is unjustifiably considered a secondary work and set aside for a long time. Someone does not have enough time, and someone does not know how to make a blind area around the house. In case of untimely protection of the foundation, soil may be washed out, and in winter, freezing may occur, which will cause non-uniform shrinkage and stress over the entire surface and cause the formation of cracks and delamination in the foundation, and then in the structure itself. The answer to the question of what the blind area around the house is for is quite understandable and beyond doubt. In addition to a protective function, the blind area also performs a decorative, attached to the completed image of the building.
How to make a blind area around the house? Work plan
1. Preparing for casting formwork
The construction of the blind area is carried out in several stages. First, the marking and measurement of the future blind area is made: from the foundation to its border it should be at a distance of 600 to 1,200 mm, from the edge of the roof to the edge of the blind should be 200 to 300 mm.Secondly, a trench is dug along the entire building, adjoining the foundation to a depth of 250–350 mm, depending on the soil and the protective layer of the blind area. Thirdly, the formation of the base in the form of layers. The first and foremost is clay, 150 mm thick, which serves as a waterproof layer that allows you to pull water out of the foundation. The next layer is sand 100 mm thick, and a layer of gravel or small gravel is poured, which when in contact with water serves as a drainage. Each layer must be accompanied by thorough tamping. Fourth, the formwork is being installed and installed; the height must be at least 100 mm; a curb can be installed instead.
2. Manufacturing foundation
In the formwork, a frame is formed in the form of laying steel mesh with links 150x150 or reinforcement is put, connected by a wire with a similar link. This will protect the blind area from cracking, will give strength and elasticity. The final stage of the question “how to make a blind area around the house” is the pouring of ready-made concrete or cement itself made in appropriate proportions (sand 1: 4, while crushed stone in concrete should occupy 75 percent of the total). The concrete is poured in small pieces at an angle of 3 to 10 degrees to the house.
3Protection and decoration of the blind area
When pouring, temperature joints are formed; for this, a regular board impregnated with waste oil will fit (it is necessary to eliminate cracks), when the board is removed, the seam is sealed with liquid glass. Between the pavement and the foundation lay a layer of roofing material (protects against the destruction of the basement coating as a result of shrinkage). A protective coating of the blind area, in addition to concrete, can be asphalt, gravel, paving slabs, crushed stone, rubble stone, self-made tiles made with the help of a plastic mold. Also important is the question of drainage. It is mounted on the edge of the blind area in the form of a concrete gutter that drains water into the common sewer system or septic tank.
How many houses, so many options can there be for his surroundings, for the inexhaustible theme is the blind area around the house. Photos with variations of this final chord of construction can be found in large quantities. So you can get a visual representation of the implementation of this type of work and, perhaps, note for yourself interesting solutions to the problem, how to make a blind area around the house on your own.
