The Vitoslavitsa company is pleased to offer customers the foundation of a turnkey house in Moscow at the most favorable cost. During foundation work, we strictly follow the requirements of SNiP 2.02.01-83 “Foundations of buildings and structures”, SNiP 3.02.01-87 “Earthworks, foundations and foundations”, SNiP 2.02.03-85 “Pile foundations”, SP 50-101 -2004 “Code of rules for design and construction. Design and construction of foundations and foundations of buildings and structures ”, as well as“ Design, calculation and construction of shallow foundations of low-rise residential buildings in the Moscow region, TSN MF-97 MO.
In its activities, the company Vitoslavitsa is guided by the rule of exact following technological maps. We propose a short excursion about the latter. When installing any foundation, Vitoslavitsa company uses various modern technologies for the greatest stability and reliability of the entire structure as a whole.
Also note that the proposed types of foundations are just some kind of framework. If you need, say, a shallow foundation of a larger or smaller section, and there is an understanding of the type of soil on the site, variations are possible:
Pile-driven foundation is able to compete with other types of foundations due to its high technical and economic indicators. The construction with driven piles is very promising when conducting construction on problem soils (soil is unstable or is subject to recharge from fresh or sea waters).
The foundation with driven piles has the status of a quick-erected foundation and is especially popular in the construction of country houses, surface buildings. It is difficult to do without it, erecting a low-rise or high-rise building with many apartments. The foundation design provides for the use of reinforced concrete rods having a square section and a pointed end. Piles are immersed in the ground using the shock method (using special equipment), while preliminary excavation is excluded.
Pile-driven foundation has a long service life, because the elements used in this design are very resistant to moisture, changes in atmospheric pressure, and also have a high refractoriness index.
Pile-screw foundation - a popular option for the foundation in the field of civil engineering, involving the use of promising pile technology. The function of the supporting element of this design is performed by a screw pile, which is a high-strength steel pipe with a cutting blade at the end, due to which the support is screwed into the ground while it is pressed into different depths.
If necessary, make adjustments to the building project or its layout, when the installation of the foundation is ready, it is possible to build up the pile-screw base without problems and special costs. In addition, the repair of the foundation with screw piles is not particularly difficult (the pile changes even with the finished building).
The specialists of the Vitoslavitsa company will measure the elevation difference and clearly demonstrate to you what corner of the future foundation and at what height it will rise above ground level.
The installation technology of a shallow foundation provides a relatively low level of labor and resource costs, as well as earthworks. The trench is digging according to a predefined marking at a depth of not less than 500 mm (in places of elevation drop deeper by the magnitude of the difference). A sand cushion is rammed in layers along the bottom of the trench to provide cushioning properties and to remove excess moisture. Next, the formwork is installed and the reinforcement is knitted.
This is a somewhat complicated strip foundation for the construction of a wooden house. “Broadening” of the sole of the base is done on soils with weak bearing capacity, which include fine sands, sandy loam and sandy sand.
The installation technology of a T-shaped shallowly buried foundation offers a slightly higher (in comparison with the tape) level of labor and resource costs, as well as earthwork. The trench is digging according to a predefined marking at a depth of not less than 500 mm (in places of elevation drop deeper by the magnitude of the difference). At the bottom of the trench, a sand cushion is rammed in layers. Next, the sole reinforcement is knitted.
The T-shaped foundation is poured twice. First a sole in which embedded parts are left. The latter, in turn, are associated with the foundation ribbon itself. The tape is poured in 2-4 days. This ensures the solidity of the structure.
It is an ideal base solution for a wooden house, especially in areas with elevation. It is optimal on clay soils and refractory clay loams.Such a foundation perfectly distributes and withstands the load from home. The voltage from the house is collected by means of a monolithic reinforced concrete. grillage and transferred to piles, the sole of which is below the freezing level and rests on dense soil. The grillage, in turn, is located above the ground and surface heaving of the soil, appearing as a result of freezing of the upper soil layers, does not cause damage to the foundation.
The installation technologies for this type of foundation are characterized by an almost complete absence of earthwork, which reduces the construction time and, consequently, the overall cost. The holes for the piles are made using a gas drill, into which asbestos-cement pipes with a length of 600-1000 mm are mounted (depending on the height difference). Pipes serve as a kind of "conductor" of concrete between the grillage and the pile itself. Next, the formwork is installed and the reinforcement is knitted.
It is an ideal solution for the foundation of any house and in any soil. This is a relatively costly and at the same time the most reliable type of foundation. This base is indispensable on weak and heterogeneous soils, quicksand and other "unreliable" soils. Also, a monolithic slab is used in the construction of basement and basement (operated) floors, when the top of the slab serves as a rough floor of a similar tier.The technology for pouring a foundation monolithic slab is quite complicated. The technical department of the Vitoslavitsa company relied here on the development of a research, design and survey and design and technological institute of foundations and underground structures (NIIOSP) named after N.M. Gersevanov (FSUE Research Center "Construction"), as well as on the development of FSUE "Fundamentproekt" and Moscow State University. M.V. Lomonosov (Faculty of Geology) under the leadership of Doctor of Technical Sciences L.N. Khrustaleva. At the first stage, a pit is developed mechanically - this is one change in the work of the excavator, and when removing soil and a dump truck - several shifts. Then half a shift goes to finalize the soil manually. A geotextile is spread on a level pit leveled on which first crushed stone and then sand are tiled in layers. On the compacted sand, a two-layer surfaced waterproofing is made with hydroglass. Further, depending on the type of soil, you can mount a layer of base insulation. The final stages are the installation of formwork and knitting reinforcement. And do not forget about the mortgage holes for future communications. In parallel, a drainage system around the foundation is recommended.
Regarding the price of this type of foundation. Take an average house of 10x10 m, in addition to earthworks by machinery and manually, for a layer-by-layer tamper, 5 KamAZ gravel and sand, 5 geotextile rolls, 26 hydroglass glass, 33 concrete cubes, almost a ton of reinforcement, formwork and other consumables are needed. You understand that it costs money, but it will give you confidence in the reliability of the foundation of your home!
It is an ideal foundation solution for wooden and combined houses, and is also suitable for the construction of a stone house, with minor changes (in particular, increasing the diameter of piles, cross-section of the grillage itself, reducing the pitch of piles, etc.). Such a foundation is especially relevant in areas with a vertical drop. It is optimal on clay soils and refractory loams, and also, in view of the expansion of the heel from below, it is also suitable on less dense loams.
Such a foundation perfectly distributes and withstands the load of the house. The voltage from the house is collected by means of a monolithic reinforced concrete. grillage and transferred to piles, the sole of which is below the freezing level and rests on dense soil. The grillage, in turn, is located above the ground and surface heaving of the soil, appearing as a result of freezing of the upper soil layers, does not cause damage to the foundation.
The specialists of the Vitoslavitsa company will measure the height difference and clearly demonstrate to you what angle of the future foundation will rise to what height above ground level.
The installation technology of this type of foundation is characterized by an almost complete absence of earthwork, which reduces the construction time and, consequently, the total cost. The holes for piles are made using a gas drill, into which asbestos-cement pipes with a length of 600-1000 mm are mounted (depending on the height difference). Pipes serve as a kind of "conductor" of concrete between the grillage and the pile itself. The so-called heel (extension from below) is made a special drill called bur-tise, which opens like a plow. Refinement is done manually. Next, the formwork is installed and the reinforcement is knitted.
The construction of the basement is possible only if the groundwater flows deep enough and the type of soil allows a significant deepening. There are only two options for arranging the foundation of a house with a zero level - these are monolithic reinforced concrete slabs or construction on the basis of a strip foundation. Both methods have their own nuances.
Digging a pit can begin at any time of the year, but in the spring it is highly likely that there will be water in it - you must wait until it leaves or pump it out. Then proceed to the formation of reinforced concrete slabs. To prevent cracking, it is held for at least 1-2 weeks, taking a break in construction.
The tape is carried out in a standard way using reinforcing bars, the distance between which should not exceed 20 cm. At this stage, window openings are organized if the project provides for their presence on the basement. It is recommended to abandon the openings on the north side of the building.
The basement itself is built of foundation blocks with a thickness of at least 50 cm. The masonry is tied with concrete mortar. It is important not to forget about the formation of technological holes with sleeves - they are necessary to ensure zero level engineering networks.
For the construction of a monolithic basement after a sand cushion, it is necessary to assemble the formwork and strengthen with spacers - this approach will reliably hold the walls and prevent their deformation under the weight of concrete. After mounting the formwork, the reinforcing cage is assembled. At the last stage, pour the concrete mixture in one go to create a monolithic structure. At least 14 days must be allowed to dry.
A buried type of strip foundation is a foundation that is mounted well below the surface of the earth. Such a solution is necessary if there is heterogeneous soil, sharp changes in relief, heaving soil, as well as during the construction of massive buildings.
The advantages of this type of foundation of the house include:
To implement the strip foundation of full deepening, first a study of the soil features is carried out in order to reveal the depth of freezing - the trench should be 20-30 cm below the set value. Then mount the wooden formwork and reinforcing cage. At the last stage, concrete pouring is carried out, which guarantees the solidity of the base. Drying takes from 1 to 2 weeks and is carried out under a plastic wrap.
The construction of the foundation consists of several stages that must be performed as qualitatively as possible in order to ensure the durability of the building:
Turnkey foundation prices depend on the complexity of the project, the number of building materials used, the location of the construction site and its features. In order to calculate the exact cost of the work, it is necessary to conduct appropriate research on the construction site. Our experts will make an estimate as quickly and accurately as possible, which will allow us to begin construction in the shortest possible time.
We believe that saving when creating a foundation is possible only without loss of quality, because it is the foundation of the structure. Our experts never deviate from the requirements of SNiP and technological maps, use only high-quality concrete and reinforcement to achieve the best result. We offer the most favorable cost of the foundation in Moscow, as you can see for yourself by reading our prices.
