How to make a break from concrete?

Even the fastest foundation cannot resist moisture and temperature drops for a long time. Moisture quickly leads to the fact that the load on the drainage system and the waterproofing of the house increases. To avoid this, install the cabin from concrete. Make it pretty simple and independently. This article will be devoted to this.

In addition to performing basic functions (preservation of the structure from the destructive effect of moisture), the coating becomes a pedestrian zone. In addition, the scene gives the private house special beauty and finished species. However, before the immediate fill of the scene, it is necessary to analyze the design features and recommendations for its installation.

Device

Concrete scenes are characterized by structural simplicity, and the following materials will be necessary for independent manufacture.

  1. Pillow (Pie). It is necessary to carry out a submission before muling in the structural grooves. This role is often performed by sand (large and medium grain), crushed stone, gravel of the smallest diameter or a mixture of gravel and sand. If you use fine sand as a substrate, a big shrinkage can happen. Due to a strong shrinkage, the design can go cracks. The most reliable option is to add from two layers: first falls asleep rubbing or gravel, which seal the soil, and then sucks sand.
  2. Laying fittings. The reinforcement grid in the design provides additional strength. The size of the grooves is usually vary – or 30 per 30 cm or a perimeter of 50 by 50 cm. The diameter of the reinforcement is 6-8 mm, however, everything is based on soil varieties.
  3. Opal. The design must be supplemented with direct boards guides. Formwork is installed all over the area of ​​the coating. Width of the guides – 20-25 mm. Formwork allows liquidation of the composition.
  4. Concrete solution. Creating a design requires the use of concrete of a special composition.

The grade of the solution is selected separately, since the type of mixture and its introductory qualities are strength, evenness and durability of sieve structures. For such a type of buildings, a mixture of M200 is often used. Strength class should start from the B15 indicator (analogue of different high values ​​may become analogue). It is necessary to take into account both characteristics such as frost resistance (perfect indicator for this parameter F50). In order for the scene to possess the best indicators of resistance to temperature changes, it is worth choosing solutions with an indicator F100. An independent construction of the scene is also acceptable to benefit, and on the price indicator.

Composition and concrete

To create a blind area around the building, it is not necessary to purchase a ready-made mixture or order a co-mixer rental. Everything can be done independently, if you calculate the proportions of the components of the materials. Mix the M200 solution for concreting can also be. Consider the recipe:

  • 1 part of the cement composition (the optimal version is Portland cement in gradation 400);
  • Filler in the proportion of 4 parts (the crushed stone or gravel is suitable);
  • The sand of medium or small graininess should be 3 parts;
  • Liquid is ½ parts of the solution.

So, to obtain 1 m³ necessary:

  • cement about 280 kg;
  • Sand about 800 kg;
  • rubbanks will need about 1,100 kg;
  • Fluids – 190 l.

Tip: First mix the liquid and cement powder, prevent up to homogeneity and only then squeeze gravel and sand.

To ensure special strength, adhere to certain rules.

Requirements for construction

All you need to know about the creation of the scene contains. Here you can find all sorts of recommendations and the main rules.

  1. The total length of the scene is obliged to be 20 cm higher than the length of the roof of the roof. If the design is drained, then such indicators are also important to consider. The best value in this case is the length of 1 meter. Such indicators allow you to put a tile track near the facility.
  2. The depth of the ribbon design is calculated half the indicator of the depth of the soil friction.
  3. The length of the length of the scenery design should relate to the perimeter of the house. However, some gap is observed when installing the porch.
  4. The thickness is also regulated and is approximately 7-10 cm, calculated for the upper layers. However, in addition to the gentlestock, parking lots are often created. In the manufacture of parking, the thickness of the scene rises and is up to 15 cm.
  5. Bias. The bias, in accordance with the general requirements, ranges from 1 to 10 cm based on the meter of construction. The most common indicators are considered 2-3 cm, which is approximately 3 degrees. Corners are sent to the opposite side of the foundation. There is no longer worth making a slope, because by too “cool” the track will be impossible to walk in winter. Farming may cause an accident.
  6. Installation of border. Although the scene does not imply a border laying, such an opportunity exists. Burgundy overlaps are better to install, if shrubs or trees grow around the perimeter of the house, whose roots tend to grow strongly. These are plants like raspberries, poplar, blackberry and t. D.
  7. Optimal height for socle. If the rigid type coatings are used, the height of the base is above 50 cm.
  8. The best indicator of the “elevation” of the scene over the soil surface is 5 cm and above.

There are several drawings and schemes regulating the construction of the erect. The design is erected from a solid concrete layer. The option is relevant for both ordinary soil and “problematic” varieties.

If you follow the recommendations of SNiP, you can even independently build an ideal gesture on a country house area.

What you need?

To begin with, high-quality disposal may be required:

  • Durable Kirk;
  • Long twine;
  • ordinary roulette;
  • Marking pegs;
  • concrete composition;
  • traaming;
  • film that does not miss moisture (geotextile);
  • formwork boards;
  • level;
  • hacksaw;
  • reinforcement material;
  • nippers, nails and welding machine;
  • the sealing composition (they will need to process the seams, a means based on polyurethane can be used);
  • Spatula, trowel and rule.

Manufacturing technology do it yourself

The technology of the construction of such structures implies several stages. Each of the steps is quite simple, having a step-by-step instruction, even an inexperienced builder can cope with them.

Marking

First you should prepare the platform. It is necessary to carry out the marking of the ribbon design. Can be used for this pegs. But there are several advice on this subject.

  1. Between the pegs observe the distance at one and a half meters.
  2. The depth of digging trenches directly depends on the type of soil. Minimum depth – from about 0.15 and to 0.2 m. If the work is carried out on the bunched ground, we increase the depth (0.3 meters).

Marking is greatly simplified if producing it in the following steps.

  1. Drive pegs in the corners of the structure.
  2. Install the beaches between the main spikes of the circumference of the house.
  3. Stretch the lace and combine pegs in a single design.

At this stage, the master is recommended to use a sealing composition to conduct a compartment of the foundation and protective coating. Then you can form a slope of structures. To do this, the trench is dried, where the depth of the first part is more different.

You can use a tree for tamping. Logs vertically, lifted. Then, with force, we lower logs down, due to which the bottom is condensed.

Creating a formwork

For the formwork building will need boards. Immediately you need to make a height of the generated pillow. At the corners, the box is fastened with metal parts. If you do not want to disassemble the formwork after completing the work, it is better to pre-process the wood with an antiseptic and wrap the boards in the rubberoid.

Arrangement of pillows

In order for the scene to be built on the necessary standards, it should be prepared by the basis for it first. The base can be both clay and sandy. The thickness of the sand layer reaches up to 20 cm. It is best to lay the styling of the pillow in one layer, but in several. Each layer you need to rub. As a result, it is necessary to align the drying solution.

Waterproofing

Waterproofing is performed when laying a rubberoid or other similar material in several layers. Specialists in waterproofing advise the following.

  1. To get compensatory seam, the material should be slightly “unscrewed” on the wall.
  2. Ruberoid or its analogue stacked straight bills.
  3. If the installation of the drainage design is scheduled, it should be installed close to the resulting “hydraulic assembly”.

Reinforcement, fill and drying

From the layer of crushed stone lay the metal network over the level of 3 cm. The step is approximately 0.75 m. Then we knead the concrete mix and fill it with the same portions in the formwork section. The layer of the mixture should be equal to the level of the edge of the box from the boards.

After pouring the solution it is worth piercing the drying surface in several places. Thanks to this, excess air will be released from the design. For the correct distribution of the mixture, you can apply a smooth or rule. Increase concrete resistance, you can the context of the surface. For this, it is covered with dry PC 400 in a thickness of 3-7 mm. Do it need 2 hours after infusion.

To avoid cracking composition, the masters recommend spraying it with water several times a day. To correctly pour the scene, it is important that the cracks do not go over concrete.

Remove the coating from moisture of precipitation will help plastic film. It is believed that the concrete surfaces of the scene will dry up for 10-14 days. However, the regulations require to wait 28 days.

Than covering?

The width, as well as the fill density with waterproofing material of the temperature and compensatory seams must be monitored. From time to time it may be necessary. For temperature seams, ribbons from vinyl thickness up to 15 mm.

If work is carried out on bunched soils, the scene does not connect to the basement. In this case, the circumference of the structure is asked drainage and landing, thanks to which the water will be assigned to the construction. Special methods help increase the tightness of concrete structures and ensure protection against destruction. A impregnation can help with:

  • cement mixture;
  • liquid glass;
  • primers (the material must assume deep penetration);
  • Hydropobizator.

The breakfast can be made by reagreeing with the help of “torn” or smooth stone, tiles, pebbles. Mustion decor elements on concrete.

Tips for repairing a breakfast

Repair small chips and close cracks by concrete solutions or cement mortar. Carry out the repair of minor flaws better either at the beginning of autumn or in the late spring. The weather during the work should be clear and dry. Repair is best carried out at a temperature of 12-10 C. It is necessary that concrete surfaces do not take over the excess water, not raw, did not destroy and did not crumble under the influence of precipitation or heat.

If the repair has to be carried out with a strong heat, it is better to choose the time of dawn or sunset. At dawn and late in the evening the impact of heat on the surface is minimal. When carrying out work it is important to understand that the fresh layer of the future cesspool must be closed by plywood, should not be located under the right rays of the sun. Under the sun, the water evaporates too quickly from the solution, and its strength and quality properties are reduced.

Create chips, small cracks and sinks can be used with mastic from a bitumen component or cement-sand mixture. Mixtures of these funds are also relevant. If you plan to repair deep rods and big chips, before work you need to conduct damage extension. You can eliminate small damage by performing work in the following sequence.

  1. First you need to clean all surfaces. After that, carefully inspect all the damage and appreciate, then you can decide how to correct the flaw.
  2. Surface cracks or chips are processed by primer several times. Puting several layers of primer, you can use a cement-sand mixture. Proportions Simple: We take 2 pieces of sand and 1 cement powder. Grouting is needed by a spatula, observing the approximate slope. 10-30 minutes after the imposition of the solution is made. Grout produced by a semiral and dry cement.
  3. To fix more serious flaws, a preliminary extension of damage is carried out. For these purposes, it is recommended to use manual devices or an electrical analog. The extender is inherent in the increase in the area of ​​flaw. At the place of damage should be a deepening in the form of a wedge. Then the site is thoroughly cleaned. When grilled, you can use a material consisting of slag, a small amount of asbestos and bitumen composition. Bitumen takes 6-8 parts at 1.5 – 1 piece of slag. Asbestos need to add 1-2 parts. After pouring to the surface, sand is falling asleep. Then everything should be good. Mastic sealant may also need.

Damaged layers are eliminated, and then new. The situation is changing if the repair is carried out on the squares without concrete or with partially cracked concrete. In this case, it will be necessary to prepare a breakfast and lay a new concrete layer.

If the surface of the surface is small, it is possible to knead the solution and independently. With a large amount of work, it is better to work with a concrete mixer. The solution is made up of rubber and sand proportions in composition 1/5 or 5 / 3.5.

It is best to use cement extremely high brands (sandbetone not lower than brand M 300). The ideal option will be the use of washed river sand (diameter – maximum 0.3 mm). Crushed stone need not very large, with a diameter of individual particles not higher than 30-40 mm.

Before work you need to carefully remove the site. Leaves, branches or dust should not interfere. Further around the edge where there is no concrete layer, we put a formwork. Old boards are suitable as materials for formwork. From the boards they pin the improvised shield.

Mix new layer of solution better in concrete mixer. If there is no old isolation on the base, you can create it yourself. This requires material in rolls or coating compositions. At the end of the repair work, before the immediate restoration of the scene, it is necessary to know the size of the distances of the fill of the new layer.

If the value turned out 3 meters or more, then it is necessary to put the temperature seam. Seam is created with the help of boards (thickness is about 20-25 mm), as well as bitumen mastic. After that, you can move to the fill. It is better to mix a lot of concrete in several approaches. Components need to be supplied gradually, separating materials on parts ratios.
