WHAT is a floating foundation


Diagram of floating foundation</a>

Floating foundation is a solid reinforced concrete slab located under the whole building.

It protrudes beyond the boundaries of the structure by 20-40 cm.

Thus, the house stands on a solid platform right on the surface of the earth.

Features of floating foundation

Floating foundation is an ideal option forConstruction on the abysmal, mobile soils. It is used for all types of buildings: residential buildings, outbuildings, special purpose structures, etc. The advantage of such a foundation is that when the soil moves, it will be like floating on the surface. In this case, the structure of the building remains intact and protected from destruction. With proper installation, such a foundation is a reliable base of the house, not subjected to deformation forces. High mobility is characterized by sandy and clay soil masses, terrain, with a high level of soil moisture. In the severe climate zone, soil mobility is significant due to seasonal temperature changes. Tape or pile foundation is not always able to withstand these loads, floating - walks along with the ground, protecting the building from distortions.

After installing the floating foundation, he mustStand up and gain strength before the building is erected on it. The ideal term is a year, the minimum is a month. Otherwise, the structure may become warped and even collapse.

The height of such a foundation can be from 20 to 40 cm, depending on the size and weight of the future structure. This is enough to provide the building with a solid foundation.
When building a floating foundation it is importantObserve all established standards. It is necessary to pour a double-layered pillow under the base of sand of rubble. Install the stiffeners and a robust reinforcement cage. Use concrete grade not less than M200. Provide reliable waterproofing, and if necessary, heat insulation of the plate.

Pros and Cons of the floating foundation

The main advantage of the tile foundation is,That it allows building strong buildings on a floating, heaving ground. Correctly erected construction of the base of the building is able to withstand even very heavy structures.

On the floating foundation Ostankino TV tower was built. Its height is 540 meters, and the height of the foundation is only one meter. This is quite enough to withstand such a massive, heavy structure.

Such a foundation is distinguished by its strength,Durability, reliability, it does not shrink. Its power does not depend on the depth of freezing of the soil, it is calculated solely by the parameters of the building. The load plate can serve as the floor of the basement floor. To do this, you only need to fill in the leveling screed, if necessary, arrange the insulation of the floor.
As a major drawback of a floating foundation, its high cost and labor-consuming installation are noted.
