Foundation Building Technology with Basement

In some cases, the owners of the houses lack the premises that are located on the surface. This problem is solved like simply – due to the organization of the basement. But it is important to consider that every such case requires the modification of the foundation of the house.

Peculiarities

The foundation with the basement inevitably goes more and more difficult than a simple analogue. The volume of earthworks increases, the consumption of structural materials increases. More will need to pay attention to the prevention of water penetration and the occurrence of condensation. To note: foundations designed for the basement, regardless of the properties of the soil and gravity of the construction are made by bellulated.

When calculating the level of soil waters and the characteristics of the Earth in a particular place.

Before making a basement in the house, you need to deal with the type of foundation under it. Most often the base makes tape. The final choice is done after studying the mechanical and bunched properties of the soil.

Important: The tape can be not only monolithic, but also the team.

The use of ready-made blocks is radically saved and allows not to be afraid of low quality work. Monolithic ribbons are formed necessarily with a formwork, and it is necessary to pour concrete into it strictly for one reception.

In any case, the need for a construction solution and other materials is found through special calculations. Be sure to place the construction site to avoid problems. Kotlovan under the tape are made as smooth as possible, and below layers of rubble and sand, which will have to thoroughly. For formwork allowed the use of durable wooden boards with a thickness of at least 25 mm. Ribbon is made to reinforce with metal rods with a cross section 1.2-1.6 cm.

It should be avoided the exit of frame elements beyond the foundation. And ideally their ends should be bundled for 30 mm or so. Special attention is paid to strengthening the corners and the lowest points. Waterproofing tapes produced by bitumen, rubberoid or more modern materials. Ribbon foundation can be used even to get a basement with a cellar.

Such a solution allows you to preserve products and other perishable things, regardless of the availability of electricity, in any season of the year. Even if the refrigerator can break, the cellar can help. And just the tape base is best suited for this purpose. If the foundation is made on the slab technology, you will have to or do the cellar at all, or equip it outside the main house.

In any case, the cellar should be equipped with some kind of building, it will improve ventilation and increase drying efficiency.

A simple basement (without cellar) can be erected on a monolithic plate. This practice is best suited for complicated soils, that is:

  • bunched;
  • sediments;
  • actively compressed and so on.

Classic slab circuit requires lowering the foundation deeper than the soil freezes. In the floating option, the mount is produced by 0.6-0.8 m below the surface of the Earth, regardless of the freezing. Kotlovan will have to dig 2 m more of the estimated plates in all directions. By reserving this place, it will be much easier to carry out fundamental work. Bottom of the pit is required to thoroughly ram.

Falling asleep the pillow, proceed to the formation of the sublimaton, that is, the ties with a thickness of 4 cm. Actually concreting is carried out using Peskobeton M300. Crushed stone need to water the portions of this solution, and not everyone immediately, only so you can get a kind of “crust”. When the preliminary screed is formed, you can already engage in waterproofing. For it, used mainly rolled materials on a bitumen basis.

An alternative to the described solutions is the foundation device under the basement from the FBS blocks. Such a design is characterized by three advantages:

  • increasing the useful area of ​​the house;
  • makes building more stable;
  • increases energy efficiency, since the walls of the underground space are insulated.

The foundation blocks differ and adapt to the gabarities of the buildings. But according to experts, the most convenient to use the largest products, and all others are best used as a good details. The fact is that no calculations and thorough cooking make it possible to avoid the occurrence of emptiness and undertakes in length. FBS is characterized by perfect safety for people’s health and environment. This material will not accumulate fungal foci and will not be amazed by the colonies of microbes.

As for the deficiencies of the FBS, it is worth remembering about their high price. However, due to the lack of fittings, the fee for the construction of 1 cube. m turns out to be less than when using monolithic plates. More seriously, the fact that joints will not be able to seal 100%. Bulk options for the foundation are much better tolerated contact with underground waters and with saturated water with soils. It is also important to remember that the FBS is severe, normal work with them without the help of automotive cranes and prepared installers is impossible.

In some cases, the basements put in the deepening below the sole of the foundation. So come if the basement was originally equipped, but then it had a need. This is possible only when using ribbons or piles. Deepen under the stove categorically unacceptable. It can end even the destruction of the whole house or other structure.

Prepare a recess under the basement below the foundation is very hard. It will be necessary to remove considerable amounts of land and strengthen the sole. Additionally, you will need to make a sandy backfill for future floors, pour concrete there, finish the walls, stretch the wiring and install electrical appliances. According to statistics, the construction of the basement in the already exploited house will be twice as expensive than the construction of it simultaneously with the housing (and this is still a minimum assessment).

It is first recommended to evaluate how deeply there is moisture in the soil; Control spend by digging pit on the hottest day of the year.

Marking for the future basement is carried out with amendment on the thickness of the outer walls. Most cellars are made in 2x3x2 m format – more serious dimensions are not always needed. It will be necessary to disassemble the screed in accordance with the markup, and only then take for earthworks. Walls necessarily need to cover two-layer inlet waterproofing based on any rolled material.

When concreting, it is permissible to use both removable and in-nozzle formwork.

In real construction practice, instead of a clean tape, plate or pile base, a combined foundation is often found. There are various schemes, how to do it:

  • place on the monolithic pillow block design;
  • Instead of writing, tie piles highly placed ribbon;
  • put bricks or blocks in the intervals;
  • Make a support plate on piles (instead of the usual sandy flooring).

The formation of a layer of monolithic reinforced concrete around the perimeter of the foundation made of piece parts allows you to guarantee the reliability of the design and combine the various parts of it. The combination of tape and pillars makes it possible to strengthen the belt base. For weak soils or for soil, prone to bent, it is this option that is considered the best. Ultimately, it will even be possible to build a heavy house on a plot with a rapid simplifier horizontal. The generated load will be distributed evenly, including such complex cases as construction on the slopes.

Important: A combination of different types of foundation under the same structure must be approved by professionals.

Attempts to make information independently, it is unlikely to benefit the right decision. And at best, then it turns out excessive tightening of construction, redundant earthworks and other additional costs. Separate miscalculations can at all reduce the service life of the house and even lead to its premature destruction. If the characteristics of the united blocks are not combined, there are cracks between them sometimes arise.

Stamp foundation under a private house attracts the attention of developers with minimal cost, ease and lack of special requirements for the experience of builders. The strongest and stable pillars are structures based on monolithic reinforced concrete. Only they should be applied where the soil can be aggravated by highly standing underground waters. It is usually taken to put pillars in the corners, at the intersections of the walls among themselves and with common.

Additional amplification is performed if the gap when setting down the main rule is greater than 3 m. During the construction of a heavy house, it is necessary to bring closer supports, but you should not put them closer than 1 m to each other, it will only create unnecessary expenses without adequate efficiency. As a transverse beam, a probable non-uniformity of shrinkage can be applied to Rastell and a tape with minor bulk.

Construction in such formats and the use of foundation blocks does not exhaust opportunities to make the base under the house with the basement. You still need to think about the pile foundation, which in a number of situations turns out to be the perfect choice for developers. Such a solution is recommended if, when moving to the depth of the soil, only weakens instead of the expected hardening.

Digging the pit for dozens of meters under a private house is impractical, wherever you want to take advantage of the pile. They are actively used on weak soils:

  • saturated abundantly humid and peat;
  • similar wood;
  • floats;
  • Plastic Suglinka.

But in very dense soil, pile designs are also helpful. They reduce the laboriousness of the work and the need for the foundation concreting. Now there are a lot of types of piles and their application modes. In order to avoid unnecessary problems, it is best to consult with experts. Without consultations, it is clear, however, that wood should be left in extreme cases. Even with solid processing with protective drugs, it serves too little.

Steel products of great value can not be mounted without cranes.

In any case, it will have to spend money on thorough anti-corrosion processing. Worth considering and increased metal costs. Reinforced concrete structures are considered the best choice. You can make them on the most construction site, if there is a suitable tool and minimal skills. Manufacture of piles from reinforced concrete in all the rules, you can expect that they will serve at least 100 years.

How to build your own hands?

Building technology on step-by-step instructions after digging pita is:

  • Failure of a cushion from crushed stone and sand;
  • breaking a cement screed;
  • water protection;
  • Formation of the foundation for the foundation;
  • Preparation of drainage (with close groundwater);
  • Overlapping base with additional waterproofing.

Independent work is good because it helps save money on the remuneration of professionals. But first you have to calculate everything. If some kind of work can be performed manually and with the help of special equipment, it is better to prefer the mechanized version. Expenses for the payment of equipment or assistance of masters will soon be justified by a significant improvement in quality. Any work with the cement pouring is desirable to perform in one working day, otherwise the strength qualities will be unsatisfactory.

Important: the foundation with the basement will not be able to build without large-scale earthworks. Therefore, the order of cargo transport for export of the withdrawn soil is necessary in any case.

After the excavator completes its work, the bottom and walls of the pit will need to be sealing by traaming. Be sure to make the calculation of walls and gender in the basement, only then it will be high-quality inside and outside. Those who build such structures without paying are in a losing position.

When calculating, take into account:

  • Whether the fittings of the wall in the foundation are starting;
  • whether the sweeping ground is brought to the top point of the wall;
  • how the overlap is performed;
  • Are the engineering and geological conditions during construction;
  • What coefficients are valid in this area.

In most cases, the basement is used not only for storing blanks for the winter. This means that in addition to the installation of walls and sex, they will still be insulated as follows. This is especially important when additional residential or workspace is organized. Reverse backfall can only be made by materials that are not prone to bent. In any warm basement, there are insulation of the caps, for this purpose, materials with zero water absorption level are used, which retain their characteristics even with moisturizing.

Most often it is recommended to use extrusion foam. Platular floors are insulated with layout of material on carrier parts between lags. The insulation layer is preceded by plating protection. A steam barrier is formed over the insulation, which will prevent the exposure to the water vapor contained in the air. The material of this barrier is placed with a raid of rolls at least 10 cm.

Even the warmest base of the house may not cope with the task. The fact is that after the fill, the tape must necessarily be reinforced. Only this approach guarantees a normal mechanical fortress. Cracks that have appeared should be immediately saturated with a solution and sweat with metal strips.

Almost always this technique stops the further destruction of the material.

Tips

When building a foundation under a country private house, it is advisable to form a single base for the whole building. If the basement is in one part, and in the other, for example, the tape – it will just get in the air. Pretty soon such a design breaks. The optimal concrete wall for the home basement has a thickness of 0.4-0.5 m. No particular need for the construction of jumpers in the basement.
