The foundation for the two-story house - which one to choose ?

Strip foundation for a two-storey house

In terms of construction practice to build a pile foundation is not profitable for the two-storey building.This is due to the fact that the price for the rental of specialized equipment, transportation and installation of monolithic pile foundation grills have a major impact on the high cost of construction in general.In connection with this pile foundation for such buildings is not applicable.The most common terms of price and quality of the tape bases are for brick houses.

most commonly used monolithic or modular tape base.Precast foundation consists of concrete wall blocks, concrete slabs, pillows thickness not less than 50 centimeters.To eliminate the possibility of ejecting the soil at the bottom of the expansion is done.To narrow elements is reinforcing metal rods.During the construction of a brick house in the place of contact between the walls and the foundation is laid PVC foil and insulation done.

Standard for two-storey buildings are considered flood bases.They are made of pure concrete filled with small or medium-sized crushed stone or gravel.Concrete is poured into a pre-prepared formwork and compacted.Due to uniform thickness may be based on a 35 centimeters longer than or quarry rubble concrete foundation.

Important!Doing the groundwork for the two-story brick house, be sure to carry out a consultation with a specialist.

Tile Tile base

base is the ratio of inexpensive materials and robust design.However, it is most often used only for building standards in the condition of weak soils.Board substrate - a kind melkozaglublennogo strip foundation.The difference lies in the rigid reinforcement, which eliminates deformation under varying loads.

floating foundation - a solid or grid plate, which is made of reinforced concrete.Such a system is used in areas with uneven compression of soil and high groundwater levels.Use a foundation in the following cases:

• Construction of buildings on the complex ground;
• In buildings where the basement is not provided;
• in buildings where basement will serve as the basis of sex.

Note!Tile base - this is a great alternative in areas of strong soil freezing.

Depth base

Deciding what to build the foundation for a two-storey brick house, you will encounter many problems.The first of these - the calculation of the depth of the foundation for the two-storey house.The depth depends on such factors:

• type locality;
• type buildings;
• material type.

depth calculation for a building with two floors and one is almost the same.The only thing to bear in mind - this is a heavy load for the two-storey house.The depth should be calculated as follows: wall thickness plus half a yard.You can also do the calculation on the basis of 80 centimeters on each floor.However, we can safely assume that the depth of the base must be of the order of 170 centimeters.The depth can be smaller than if you use the valve.Not just dig a trench and fill it with stones, it is safer to install a reinforced concrete structure.

Tip!Make the depth with a small margin.
