How do blind area around the house with his own hands: Practice, Tips

Construction of the blind area with their hands

designing otmostki

The first step is to choose the width of the strip. According to the standards, the minimum value is 0.8 m. The maximum size is not regulated, but the average are from 1 m to 2.5 m. This takes into account and the time that the blind area around the house is to track walk. Than it is wider, the easier it is to walk through it. And most importantly, the less likely it is undermining and foundation deformation. And yet, to diversion of water to be effective, the concrete strip should extend beyond the eaves of the roof about 30 cm.

The second important parameter - the degree of inclination of the strip in the direction of the wall. According to Soviet GOSTs deviation value varied from 50 mm to 100 mm per meter of width. This means that a portion of the blind area of ​​the house, adjacent to the wall, will have a height of 5 to 10 cm, and the opposite edge is flush with the ground. Such a roll is good for rolling water, but walking through it will be difficult.

Scheme create otmostki

Today, a compromise between functionality and comfort is considered the height of 15 mm to 1 m. When walking, it is hardly noticeable, and water this bias does not linger. If the web surface is smooth, it is sufficient and 10 mm per 1 m. However, it is worth noting that such a roller track turn winter.

Useful advice!If the belt is around the garage ramp should be at least 20 mm per 1 m. Then the entry will always be dry.

Preparatory work

Solving the problem of how to make a blind area around the house with his own hands, the first thing the finished ground. The basic element of the blind area is traditionally a concrete screed. Work on its installation in the following order:

• base layout. At a distance, for example, 100 cm from the base, trying to drive the pegs around the perimeter of the house. Pegs on pull cords. On it will be the boundary of the web;
• excavation. Our task - to remove the fertile soil of about 20-25 cm (with a bayonet spade). The depth of the trench must be the same everywhere. The side wall of the foundation must also be thoroughly cleaned. The smaller the land on the contact surfaces, the stronger the adhesion of concrete layers;
• laying sand cushion. Aligns the bottom of the trench and compacted, it is best to shovel. Top evenly fall asleep sand;

blind area of paving slabs

Useful advice!Sand for pillows should be uniform, no broken bricks and rubble. Large blotches did not enhance layer, as many believe. On the contrary, in the spring of blistering sand soil pushes them out, destroying the concrete.

• sand layer spill on water twice and sealing rammer. Water can be sprayed from a garden hose with a divider, or normal watering. If you stand on the finished sand bed, it does not fail, but remain clear traces of soles. This means that between the grains almost no airbags. Poor compacted sand will continue to sink, forming cracks in concrete;
• Cushion poured gravel layer thickness of 8 cm. Macadam laid on a mesh with mesh size of 5 cm. If instead of the grid rods are used, they should link together with wire. The distance from the reinforcement to the upper edge of the trench should be 5-7 cm.

Formwork with reinforcing mesh

How do blind area around the house with his own hands: the main work

In most cases a trench concreted by mounting the removable formwork of 20 mm boards. But it can be done easier - along the rim, strictly on a cord, install the curb. This can be red bricks or curbs. Between the stones leave a gap of 10-15 mm. It is necessary to ensure that the solution flows into the joints to form a further solid ligament.

Apparatus concrete otmostki

Apparatus expansion joints

Monolithic blind area around the house just to make difficult. You have to order just two concrete machines and a team of workers. But there is a solution - split the band into blocks. To do this, take wooden slats 10 mm and put them crosswise formwork every 2-3 m. The volume of the section should correspond to the amount of concrete in one batch. Rods should be pre-soak or working off the bitumen. And most importantly, such concrete lintel reduce internal stress at the diurnal temperatures races. You must install them in the corners of the building.

Useful advice! If you are afraid that between the rail and the concrete can leak water, it is better to make expansion joints of special sealant.

Creating a blind area around the house with his own hands

At the junction with the cap otmostku also perform a movement joint. This gap width of 1-1, 5 cm, sanded or stuffy roofing material. You can lay in a joint bundle of Styrofoam, compacting it with a piece of plywood. If the blind area still prosyadet, then it falls down the seam. A cap will remain intact.

Fill blind area

Concrete kneaded standard proportions 1: 3: 1 (1 part cement, 3 parts gravel and sand 1 part). Pour the mixture by sections, setting on edge transverse slats. The upper ends of the webs have to coincide with the strip surface. Slats simultaneously serve as beacons for leveling concrete. Therefore, they just need to put to the desired degree. Concrete is spread wide spatula or plastering trowel.

Fill blind area of ​​cement mortar

The mixture was compacted by pouring or vibrator or iron rod (shtykovaniya method). Length of reinforcement is immersed in concrete and rock the rotary motion. Likewise are all blind area. As a result of frequent penetration of air bubbles and excess water will rise up, and concrete becomes denser.

Next, the wet surface of the belt type iron to give it strength and water resistance. For this scatter dry cement in concrete and wait until it absorbs water. Then take a metal trowel and rubbed cement concrete surface to achieve a dark gray color.

Scheme insulation and waterproofing otmostki

The finished blind area is covered with burlap from the sun. If there is no rain, the material is poured from a watering can, wetting the concrete. Otherwise, he will seize, not having time to collect the necessary strength.

Finally. Blind area around the house could easily fill a person with no construction skills. Carefully made concrete screed not only protect the foundation from the rain, but also give the building a finished look.
