Soft blind area around the house: device, step by step instruction

Usually the blind area acts as a continuation of the pavement. However, this condition is not always met, because it is not mandatory. As an example of this approach, you can consider a soft blind. Besides functional, it has decorative advantages. But before starting work, you should familiarize yourself with the technology of their conduct, as well as prepare the necessary materials.

The essence of the idea

You can change the exterior of the house using the solution described above. Cobbled and concrete paths have become boring, and not always they look natural. With some types of foundations, they simply do not combine. For example, pile-grillage base requires the decoration of the inner edge of the blind area with a hinged base. In this case, the ventilated internal space under the floor is closed.

Key Features

If we are talking about hard areas, then their main principle is to continue the yard covering and finishing the socle. But the soft blind area is almost a part of the front garden or flowerbed, the last of which is adjacent to the house. As practice shows, such a coating is durable, durable and does not require major repairs. If we compare the complexity of the device and the complexity, then both types of blind area are identical, but the layers are arranged in different sequence.

Device of soft blind area

A soft blind in the classical scheme provides for a well-compacted layer of soil. If we are talking about the traditional design, then in it water is taken over the coating and falls into open trays. In the case of the described blind area, this role is assumed by surface drainage. In order to ensure the stabilization of the surface, a preparatory layer of coarse-grained gravel should be made. The stones will evenly distribute the load and eliminate the shrinkage of the bulk coating.

The main slope can be provided with a layer of crushed stone. Alignment is achieved by a bulk layer of fine material, which has no tendency to whipping. Usually, sand is used for this, but slag or granite screening can be used, if necessary thermal insulation - expanded clay. A soft blind area should have a hydro-barrier. For this, geomembranes are usually laid, which are used for waterproofing buildings and are sold under the names "Izudud" or "Fundalin".

If it is a ribbon foundation, then the blind area is located along the perimeter, as well as the usual one. Whereas at the pile-and-grove foundation, the blind is put inside by 50 cm. This makes it necessary to equip the blind area during the construction of the foundation. Waterproofing barrier will not be damaged, and excavation will be more convenient.

Step-by-step instruction

If you will be equipped with a blind area with your own hands, the step-by-step instruction presented in the article will help in this. At the first stage, it is necessary to perform excavation work, for this the ground should be removed by trench, having deepened by 45 cm in relation to the lowest point of the site. The bottom should be at a constant level, so the work must be preceded by marking with a water level or a level.

When the blind area is equipped with its own hands, a step-by-step instruction is always studied before this. From it you can find out that the edges of the trench do not need to be strengthened, but a ditch should be formed along the perimeter. It should place the channels of the storm system. The bottom should be prepared and compacted. It is usually covered with a layer of fine-grained rubble.

On the leveled surface is laid moistened greasy clay. The final thickness of the layer should be 20 cm. From clay it is necessary to make a common plane and a tray for a shower channel. Clay should be laid with a common slope toward the building. The device of a soft blind area around the house in the next stage provides for the stage of pouring a layer of preparation. It must be periodically sprinkled with water to prevent cracks. Finish the device otmostki possible after the clay cease to bog his feet.

Provision of stormwater drainage

Remove the liquid from the blind area into the drainage system. Dumping of sewage can be in the soil, which will depend on the annual level of rainfall and rainfall intensity. The abundance of draining liquid can wash the ground under the blind and cause a strong bias of the hydrobaryar. As a result, the bulk layer will begin to blur.

If there is no drainage channel and a filtering well in the vicinity, the discharge can be carried out into the soil, away from the total drainage slope by about 10 m. To collect water, drainage pipes with a diameter of 100 mm are usually used. Prepare the product follows by perforating the walls. The diameter of the holes can be equal to the limit of 16 to 20 mm.

Soft otkostki around the house with a backfill of earth provides for wrapping pipes in needle-punched geotextiles. Despite the fact that the blind area has a high filtration capacity, protection will be required in case of migration of moisture from the muddy soil side. At the intersections and angles, the channels must be connected by cruciform or triple collectors. It is important to ensure that there are upper taps that are needed for revision.

If the valves are not used for drainage, then the revision wells can be replaced by drain neck. Water is discharged into a trench, the depth of which reaches 1 m. It should be covered with crushed stone and fertile soil. Perforated pipe acts as the distributor.

Cake pie

Clay preparation should be sprinkled with a layer of rubble, which is located with a certain bias. The thickness of this preparation is 120 mm. The fraction of the material varies from 15 to 20 mm. You can alternate small and large filler. Slope alignment is performed by a drop-out or sand layer. The deviation from the horizon is 3: 100.

Blind area of rubble will go under the house. From the border of the facade, it should be raised from 15 to 20 cm. The cake should be compacted as it is laid and watered. The stability of the layer is improved at the boundary of the rubble and clay. The surface of the sand after compaction is stretched by the rule, the membrane is spread over the surface. Blind area of crushed stone is arranged in such a way that there is no additional padding in the tray. As an exception, a few centimeters of a mixture of sand and gravel, with which you can create a slope for the drainage channels.

Shaft for well

Soft pavement of the well consists of a waterproofing film, which is filled with sand. From above it is possible to arrange a lawn or a decorative covering. The production of such a system does not involve large physical or financial costs. Before the beginning of the work, it is necessary to remove the fertile soil around the well for a width in the range from 1.2 to 1.5 m. A waterproofing foil is laid on the bottom, the edge of which should be placed on the upper ring.

In the role of waterproofing can act frostproof film, which fits into the ground when building foundations. The film can be fixed to the ring with a double-sided tape or a metal strip, through the last fastening it is carried out by screws or dowels. In the place where the film goes into a vertical position, you should make a crease. It will compensate for the material displacement and soil subsidence, which will eliminate the destruction and damage to the decorative top layer. Above you can cover the sand and lay paving slab, rubble, brick or paving stones. Sometimes the place is simply returned to the removed turf or grass lawn is sown.

Conclusion

Information on how to arrange a soft blind for a pile-screw foundation was presented above. It should be remembered at the same time that work needs to begin with the formation of a compensation suture. This will waterproof the underground and eliminate the deformation of the socle. The work can be done with a two-layer ruberoid. Further excavations are carried out. It is necessary to go deeper by 0.3 m along the perimeter of the house and fill up the materials with a ramming. At the final stage, a gutter is installed, the surface is covered with cobblestones or paving slabs.
