Bookmark of the foundation: the specifics of the work of earthwork

The preparation of the soil for the subsequent laying of the foundation manually is a fairly laborious and burdensome process. Its first stage is excavation, the cost of 1m3 of which varies depending on the features of a particular project. In some cases, when the relief features are required, it is worth making excavation manually, the cost of 1m3 of which is significantly reduced.

It is worth noting that the basic conditions for creating a strong and durable foundation are manually:

accurate calculation;

the correct technology of soil preparation;

high -quality reinforcement;

compliance with accurate proportions in mixing concrete solution;

phased filling;

Reliable waterproofing.

Earthwork as a basic stage of bookmark

During the construction of a house, a tape type of construction is most often laid, the cost of which per 1 m3 is quite democratic.

Earthwork is carried out manually, the cost of 1 m3 varies depending on the price list of the developer company or individual agreements. At the same time, the cost of 1 m3 of manual excavation depends on the complexity of the technical tasks to be solved when preparing the soil for the foundation.

The depth of excavation and its density also matter.

It should be noted that in case of individual construction earthworks are much more often carried out manually, which significantly reduces the cost of their cost per 1 m3. In any case, an important factor in the preparation of a trench or foundation pit is the calculation of the depth.

In addition, when preparing a tape trench, it is worth considering the installation of formwork. It is recommended to take into account approximately 15-20 centimeters in width on both sides, and at least 15 centimeters in depth.

Compliance with this norm will allow you to mount high-quality and durable formwork, which will subsequently become the key to a reliable strip foundation.

Tape base: calculation and cost

In individual construction, the most commonly used is a strip foundation, the calculation of which is based on a combination of factors of natural relief, technical characteristics of the soil and the expected mechanical and physical loads associated with the design and operation of the building.

Design parameters determine the calculation of the complexity and cost of earthworks 1 m3. A feature of the strip foundation, laid by hand, is its reliability and stability, as well as affordable cost.

Earthworks are carried out along the perimeter of the building.

The strip foundation is a monolithic reinforced concrete strip, the thickness of which in any section remains the same.

One of the basic conditions for creating a high-quality tape-type foundation is the correct reinforcement of the structure and the gradual pouring of the concrete mass.

Careful calculation and high cost of such technology are justified by its positive technical characteristics.
