Foundation for a wooden house, types and features

The foundation is the foundation of any building. If an error is made during its calculation and construction, it will lead to serious, if not dramatic, consequences. When designing the foundation, the composition of the soil, the availability and horizon of groundwater, and much more are studied. After studying all the factors, it is calculated and the choice of the design variant. If small wooden houses are to be built, then everyone can calculate the foundation independently. If it is a brick building on several floors, then in this case it is better to turn to professional designers.

The foundation for a wooden house has a design that has been used since ancient times and has reached our days, without fundamentally changing. The foundation, as such, was practically nonexistent. The house was set on large stones or wooden logs. And today the foundation for a wooden house is columnar, in fact, with an amendment to the modern level of technology and materials, repeating the ancient design. In addition, there are ribbon, slab and pile versions of the basement.

Light country houses made of wood, the construction of which does not provide for the installation of a basement, you can put on the foundation of the pillars. It can be made of stone or wood. When the columnar foundation is made of wood, poles are used, which are the lumpy parts of the logs made of pine or oak. The pillars are laid down on the foundation pit on stone or concrete pillars. Negative moment in this case is the fragility of wooden structures. You can get rid of this defect by using poles made of stone. In this case, the poles are made of granite or quarry stone.

The most common is the ribbon foundation for a wooden house. There are monolithic or prefabricated structures of such foundations. If the project involves the installation of a basement, then it is better to plan a strip foundation, performed by a solid monolith. If the construction of the house with a basement is provided with a strip foundation of the prefabricated structure, then it will be necessary to take care of good waterproofing of the basement. Because moisture through a lot of stitches will penetrate the basement.

If groundwater approaches quite close to the surface of the earth, then it is advisable to use a slab foundation for a wooden house. The basis for it is a solid reinforced concrete slab, which is manufactured locally.

The construction of the pile foundation is used in the construction of the building in conditions of weak soils. Apply piles and pendant piles. Piles-struts perform a length of no more than 6 m. They pierce the weak soil to more solid layers, to which the load is transferred. Hanging piles in their upper part are united by monolithic beams-grillage. The load in this variant is transmitted through frictional forces between the beams and the dense ground. The pile foundation requires the use of special equipment in its production, making it a rather expensive option.

With the preliminary calculation of the cost of building a house, the question always arises: how much does the foundation of the house, which is performed in one form or another, stand. The cheapest is a block foundation for a wooden house.

The cost for the unit with the installation is 1200 rubles. The most expensive - plate reinforced, the price of which reaches 7200 rubles. For one square meter. The pile foundation has an average price, for one installed pile it is necessary to pay 5500 rubles.

There are many options, and for each specific situation suits its own. Therefore, sometimes it is better to get professional advice.
