Often the owner, build their own house, often financially constrained and it arises the problem of how to produce calculation options Foundation of his house, so he served with no problems and for a long time. To calculate the foundations of the house, preferably all, of course, to refer to the estimator in the company of the Engineering Guild. They have sufficient experience and knowledge in this. Of course, you can contact your neighbors or friends associated with the construction and learn the device and methods of calculation of the Foundation. But with this approach you can get the waste of material or the Foundation will not high quality and not reliable, respectively, over time it can deteriorate.
Each Foundation requires an individual approach, accurate and relevant calculations, and of course proper execution. We will help you to calculate the parameters of the Foundation. Here's what you need to know when the full payment of any Foundation:
- on the place taken into account soil bearing capacity;
- calculation of deformation of the substrate;
- description of soils;
- the level of soil freezing;
- groundwater level;
- weight of the snow on the roof (load).
Soil is the Foundation for Foundation, he must have strength and be resizemap. To find out how to do the Foundation, it is necessary to know the characteristics of the soil. Bearing capacity of soils allows you to set what should be the area of the basement under construction: the more the load can withstand the soil, the less should be the area of the basement. Soil bearing capacity is determined by three factors is the groundwater level, soil type and soil moisture. There are several types:
Indicators of soil quality depend on the complexity of construction and the costs related to this process. In order to assess the soil on the site, you need to drill a couple of wells or dig some holes. Why? In many cases, the soil of the plot is different, respectively, and the properties it possesses different. No need to rely on research neighbour - it threatens not good effects! This is done as follows. Dug a pit depth of about 2 m - depth enough to understand what kind of soil needs to be worked on. Even his appearance, depth, thickness of the individual layers, will tell us about some of the grounds should be preferred, and from what you can give.
You need to understand that lying at a great depth of soil layers with natural hydrostatic tests are different and have different resistance values.

Depth of foundations
Some developers mistakenly believe that with the greatest depth, Foundation will be stronger. This will ensure reliable operation. This is partly true, if the sole Foundation lies below the depth of frost penetration, then the force of the swelling from the frost will not exert pressure on him from the bottom up, i.e. to bring it up. However, you need to remember about the tangent side and frosty swelling. It operates on the entire surface. Sometimes, the swelling snatches the Foundation and separates the lower from the upper part. This happens when masonry blocks, small blocks or stone under lightweight frame houses made of wood.
To avoid the destruction of the Foundation (of the blocks, brick or stone) on the heaving ground, you need to put it a little below freezing and to minimize shear forces, lateral and frost heaves.
Blind area Foundation for this insulated Pompano, foam, or expanded clay.
If its not to warm, then it is important and necessary to perform a bunch of Foundation walls (brick, stone or block) metal reinforced frame. Lay the frame over the entire height of the Foundation, linking the upper and lower part. If you do not produce a reinforced metal frame, then the bottom wall of the base should be broad, and to top smoothly to narrow. This method will greatly reduce the lateral, tangential and frost heave of the soil.
Width of the foot of the basement.
Any soils perceive pressure from standing on it private homes (excluding silts and peat). Typically, an individual house has a small weight and size.
If the bearing capacity of the soil is negligible, it is necessary to increase the area of the soles of the Foundation to reduce the pressure on the ground. If you increase the square foot basement, ground pressure is reduced.
There are two major measures for the correct calculation of the width of the sole Foundation. They need to know, it is the mass of the house (including snow loads) and the type of ground on which to stand the house.
Several times recheck their calculations before the construction of the Foundation. 's future depends on your home, its safety and reliability. Of great importance and savings funds, expenditures for construction materials.
It must be remembered that the calculation of the deformation of the soil is very complex and it is better to entrust its execution by the professional company, the Engineering Guild.
