Any major construction begins with digging a foundation pit and building a foundation. The foundation is called the supporting
a base that transfers the load from higher structures to the ground. The durability and reliability of the building itself depends on how well and correctly it is designed. Therefore, the construction of foundations should be treated responsibly, because correcting errors is a very expensive task. The most correct thing, of course, is to prepare a project before undertaking construction. But often the owners of suburban areas neglect this rule.
Calculation of the foundation cube
How to calculate the foundation cube? This question was asked at least once by every novice builder. Meanwhile, to do this is not difficult at all. It is enough to know the school course of mathematics and such parameters of the future foundation as length, width and depth. These three indicators are multiplied among themselves. Previously, all quantities must be converted to meters. Let's look at a specific example of how to count the foundation cubes. For example, the length is 25 m, the width is 60 cm, the depth is 70 cm. We translate everything into meters and multiply. It turns out that for pouring such a foundation, 10.5 m 3 of concrete will be required.
The importance of soil composition
In order to qualitatively perform work on the foundation, you need to know what types of soil the new structure will stand on. So, for example, sandy soils have such a property as subsidence. Therefore, the foundation on them is laid to a depth of 40 to 80 cm. Clay soils tend to freeze, so dig a hole under the foundation is necessary to the entire depth of the clay, to another rock. How to calculate the foundation cube in this case. First you need to find out to what depth the clay horizon lies.
The depth at which it is necessary to fill the foundation also depends on the depth of freezing of the substrate. And she, in turn, is determined by geographical location.
If the depth of the foundation device depends on the soil and groundwater, and the length on the dimensions of the structure, then the width - on what thickness of the wall will be built. Typically, the thickness varies from 20 to 40 cm.
Understanding how to calculate the foundation cube is not a difficult task. It is more important to decide what it will be. There are several types of foundation. The most common are tape and columnar.
Column foundation is cheaper than strip foundation. Most often it is used on deep-freezing soils. But with its device, difficulties arise with filling the space between the posts, as well as between the ground and the wall.
Strip foundation
The strip foundation is the most common. It is usually erected during the construction of a building with heavy walls, and in private houses - for the subsequent installation of a cellar or basement.
Depending on the materials used, sand foundations, crushed stone, rubble, brick are distinguished. When adding crushed stone to concrete, the amount of the latter will decrease. A professional will tell you how to calculate the foundation cubes necessary with this version of the device. Since you need to know the percentage of adding crushed stone or other material. Also, the question of how to calculate the foundation cube will arise when using reinforcement. In addition to the above, it is always necessary to take into account the standards of concrete compaction and take its amount 2% more than calculated.
