How to make a blind area the hands

When we got the house with a site in the village, at once there was a set of questions concerning repair. Anything surprising, after all house though strong, but nevertheless not new. Therefore before enjoying rest and harmony of rural life, it was necessary to solve a number of pressing problems. And the blind area became one of such problems.

When we got the house with a site in the village, at once there was a set of questions concerning repair. Anything surprising, after all house though strong, but nevertheless not new. Therefore before enjoying rest and harmony of rural life, it was necessary to solve a number of pressing problems. And the blind area which was already so ancient that did not carry out the functions became one of such problems. It was simply impossible to ignore this fact as, without having a blind area, the base by all means would start collapsing. And restoration of the base – business very expensive and labor-consuming. So that having had a talk with skilled builders and having studied the Internet, we turned to work.

What is the blind area and for what it is necessary

The blind area is the paved strip which adjoins directly the base of the building or a socle. The blind area is a peculiar bridge for the water flowing from a roof during a rain or thawing of snow. The main function of a blind area – not to allow water to get to the house base. For this purpose the blind area has to have a certain tilt angle that to water was where to flow down.

It is simple to imagine that will be with the base if the blind area is not in general or it will be low-quality. Water, as we know, sharpens a stone. Therefore the zealous owner has to worry about an appropriate condition of the house in time.

That is required for construction of a blind area

As a rule, the blind area consists of two layers. The lower layer is called spreading, and top – protective. As material for the lower spreading layer sand and crushed stone is used, it is possible to use clay. We ordered the truck of small gravel, so-called elimination. Something between crushed stone and sand.

For creation of the top protective layer it is possible to use different materials, such as: asphalt, paving slabs, concrete, cobble-stone. The main condition – the top layer has to be impenetrable for water.

Our blind area is constructed by the most widespread option – as the spreading layer small gravel, and the top layer – concrete was used. Therefore here I will describe an operating procedure with these materials.

Concrete filling, naturally, will require cement. How many bags with cement to get? This question demands a reality in each separate case. Everything depends on amount of works. Preparation of solution for filling will require usual sand. Take care and of capacity for concrete mixing. For this purpose perfectly the old bathtub approaches.

Construction of a timbering will require some boards. It is also good to have a reinforcing grid which protects concrete from cracking. For the same purpose it is quite good to reserve some large stones cobble-stones.

Still without fail the shovel, lomik, a wheelbarrow for earth transportation, a trowel for smoothing of concrete solution, pegs for a marking will be required. Here, perhaps, and all.

Operating procedure

Before making a blind area, everything is necessary correctly to calculate. Width of a blind area has to be a little more, than eaves carrying out of a roof. Usually width varies within 80-100 cm. At first we do a marking by means of pegs and a rope.

The main work begins with preparation of a trench of the necessary depth. Usually minimum depth of a trench – 15 cm, but, I think, it will be suitable only for steady soil. We took out the earth on a shovel bayonet, that is on depth of 25 cm. It is specified in various sources that it is necessary to remove a fertile layer of earth that roots of plants would not destroy a blind area. In practice this work is simple and demands only physical force and endurance. We load with a shovel the removed soil in a wheelbarrow and we take out it to a certain place. In advance think where to take out the earth. It is possible to fill up with it any holes, or it is simple to scatter an even layer near the house.

When the trench is ready, we begin to fill it with sand or gravel. Everything is carefully stamped, we level for what we water sand a little. It is possible to make one layer of sand, and from above to fill crushed stone. The sandy pillow has to reach earth level. Some of readers of can manage, as well as we, only gravel. Further we begin to make a timbering of in advance prepared boards. The timbering is similar to a trough without bottom. Inside we stack a reinforcing grid. And over a grid we stacked cobble-stones that the concrete surface was stronger.

So, we prepared the lower spreading layer and we start laying of the top protective layer. For this purpose we prepare solution of cement, sand and water. We used brand cement – 400. On 1 bucket of cement we take 3 buckets of sand and we add water, gradually stirring slowly. If solution turns out too watery, it will be necessary to add a little more cement and if solution is dryish, add sand and water. It must be kept in mind that it will be necessary to make use of the prepared solution within an hour.

We fill in solution and we smooth, we level it by means of a trowel. Concrete needs to be poured so that to observe a bias from the base on 3-4 degrees. For improvement of a waterproofing still strew a wet surface with cement and smooth with a trowel. As filling of concrete is carried out by small sites, approximately on 1,5 m, upon termination of the main work it will be necessary to see to it about a fastening of the arisen seams. These are so-called temperature seams. They are necessary in order that at expansion and compression concrete did not crack. For a fastening of seams we used polyurethane sealant. For the same purpose it is possible to use flexible vinyl tapes.

Drying of concrete has to be gradual. Therefore if weather costs solar, several times we water a newly made blind area from a leechka.

On it the main works can be considered ended.

Additional councils

It would be very correct to provide a small storm flute along a blind area. We did not do it as our house is on a hillock and water safely flows down down.

If in the house there is a first floor, it is possible to make a blind area warmed. For this purpose before concrete filling directly apply a polyurethane foam layer on crushed stone. This synthetic material is applied in the form of foam from a special spray and in 15 minutes it is possible to start concrete filling. This way of warming of a blind area is simplest and does not demand additional works and knowledge of special technologies. But it is possible to use also other ways of warming which assume laying of plates of a heater on the spreading layer, use of waterproofing materials – roofing material, a film etc.

The blind area can be not only functional, but also decorative part of the house. For this purpose over a concrete coupler paving slabs or a decorative cobble-stone keep within.

Repair of a blind area

It is necessary to watch a condition of any blind area, that is in due time to notice emergence of cracks and to liquidate them. If cracks small, fill in them with cement mortar. It is especially attentively necessary to look narrowly at a place of joining of a blind area with the base. The best time for repair of a blind area – fall and spring as at cool damp weather seams and cracks strongly extend.
