How to calculate a foundation cube for an amateur builder

Any capital construction begins with excavation and foundation construction. A foundation is a support The base, which transfers the load from the superior structures to the ground. On how well and qualitatively it is arranged, the durability and reliability of the building itself depends. Therefore, it is worth to take responsibility for the foundation of the foundation, because correcting mistakes is very expensive. Most correctly, of course, before undertaking construction, prepare a project. But often the owners of suburban areas neglect this rule.

Calculating the foundation cube

How to calculate the base cube? This question was at least once asked each novice builder. But meanwhile it's not difficult to do it. 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 the values must be converted into meters. Let's consider on a concrete example how to count the foundation cubes. For example, the length is 25 m, width 60 cm, depth 70 cm. We translate all into meters and multiply. It turns out that 10.5 m ^{3 of} concrete will be needed to fill this foundation.

Importance of Soil Composition

To qualitatively perform the work on the foundation of the foundation, it is necessary to know on what types of soil a new structure will stand. So, for example, sandy soils have a property such as subsidence. Therefore, the foundation on them is laid at a depth of 40 to 80 cm. Clay soils have the property of freezing, so digging a hole under the foundation of the foundation is necessary for the entire depth of clay, to another breed. How to calculate the cube of the foundation in this case. First we need to find out to what depth the clay horizon lies.

The depth to which the foundation is to be filled depends also on the depth of freezing of the substrate. And it, in turn, is determined by geographical location.

If the depth of the foundation depends on the soil and groundwater, and the length of the structure, the width - from the thickness of the wall will be erected. Usually the thickness varies from 20 to 40 cm.

Understand how to calculate the cube of the foundation, the task is not difficult. It is more important to determine what it will be like. There are several types of foundation. The most common are belt and columnar.

The pillar foundation is cheaper than the base. Most often it is used on deep-freezing soils. But at its device there are difficulties with filling of space between posts, and also between the earth and a wall.

Ribbon foundation

Ribbon foundation is the most common. It is usually erected in the construction of a building with heavy walls, and in private homes - for the subsequent installation of a cellar or cellar.

Depending on the materials used, sand foundations, gravel, butovy, brick are distinguished. When adding rubble to concrete the amount of the latter will decrease. How to calculate the foundation cubes, which are necessary with this version of the device, the professional will tell. Because you need to know the percentage of adding rubble or other material. Also, the question of how to calculate the cube of the foundation will also arise when using reinforcement. In addition to the above, it is always necessary to take into account the standards of compaction of concrete and take its quantity by 2% more than calculated.
