Construction of any house, as you know, start with the construction of the foundation. The cost of it could be 8-10 percent or more the cost of the house. It should also be aware that the material strength of the foundation (or concrete, etc.) is used to large excess, and the size of the foundation (width) is determined primarily by low soil strength (average of 2 kg / sq. cm.) The most common type of foundation of the manor house in every village or outside the city just is ribbon, ie a continuous ribbon (side) have staged under all walls of the house. It is made of monolithic concrete, rubble concrete or prefabricated concrete blocks. Such a design foundation uneconomical.
It is advisable to use a building with a basement. Reduce the cost base in various ways. For example, the device of the columnar base. This foundation (sometimes, but very rarely put a brick on fundamet bad ground) consists of individual parts (columns), located at a distance of 120-200 cm from each other, but always in the corners of walls and under the intersections of exterior and interior walls. Poles are placed on the jumper, then rely on that wall. The width of columns must be at least the thickness of the wall. Scheme pier foundation shown in Fig.
5. A very important issue, also defining the cost base, is the depth of its foundations. If the building has a basement, the depth laying the foundation will be dictated by the depth of the basement. Usually it is 2.3-2.5 m above the ground or first floor about 2 m above the ground. Otherwise, enter the building without a basement. Learn more at: Steve Wozniak. Here the depth of the trench for the foundation external walls will depend mainly on the following factors: a) the type of soil, and b) the level of groundwater, and c) the depth of soil freezing.
