Due to objective reasons, most people prefer not only to the quality of materials, but also their economy. To one of the structures that the data feature is inherent in the block foundation.

Benefits and types of design

Blocks for foundation are characterized by:

• increased strength;
• frost resistance;
• solid operational period;
• resistant to the effects of chemicals;
• wide range.

Bookmark blocks are carried out in extremely short time and without technological delays. As inherent in the monolithic design. The unit of block foundation is also quite acceptable for each owner of the country area. The main component is the weight of the erected structure. If the house is big, then, accordingly, the foundation from blocks should be made of massive.

There are such basic material classifications:

• in form;
• in appearance;
• by weight.

In the form of blocks are divided into wall and custoded structures. Wall blocks are a quadrangle. Applied when arranged both ground and underground parts of the foundation.

Pillow blocks have a trapezoidal form. They are characterized by an increased reference area. From this material, the first number of the foundation of the house is laid out.

Classification by appearance implies the division of products depending on the availability of technological gaps. The blocks are:

• integral with cutouts (VBW);
• hollow (FGF);
• one piece without holes (FBS).

The latter material is the most popular according to reviews of the foundation block.

By weight of units can be:

• heavy (concrete);
• lightweight (it expanded clay).

The two main ways to create a foundation

Block foundation for the house can be set up tape or columnar manner. The most appropriate solution for the creation of the strip foundation is the use of CFC blocks. It is a reliable and solid foundation for buildings with more weight. Walling houses can be started immediately after the laying of the foundation block their hands.

Small wooden houses will be the best option tab columnar base. The main advantages of this technology are:

• minimal complexity of the process;
• low cost of the foundation block;
• small construction area;
• ease of erection.

erection work

Now directly to how to make a block foundation. The primary task - is to conduct geological exploration area. It will determine the depth of the trenches for the "sole" of the house. This is followed by marking work. axes provides a breakdown of their transfer to the prepared foundation. On axial risks are determined by the size of the foundation under the block of flats. Tensioned cord must be at a distance of 2-3 mm from the side face of the foundation.

For quality bookmarks foundation under the house need to create a sand bed. In the presence of sandy soil, and blocks can be laid directly onto the bottom of the trench aligned. In other cases it is necessary to fill the trench sand bed 5-10 cm. The length and width of the sandy grounds made by 20-30 cm longer dimensions of the foundation. This prevents the drooping blocks. In any case it is impossible:

• created under the pillow or leave loosened bulk earth;
• pouring the foundation to produce ground covered by snow or water.

Installation work begins with stacking units at the corners and at places where it is planned intersection of walls. Such units act as beacons. After their installation tensioned cord, which occurs on the intermediate mounting block. The cord moves as the installation following series material.

The elimination of small deviations is carried out by moving the block with a scrap. The smooth location of the bearer blocks is carried out with the help of the level, and the rest - on the cord. When the installation of a particular block was carried out with an unacceptable deviation, it should be pulled out with a crane. The base is aligned, and the block is re-falling into the trench.

The main stages in the block of block foundation are:

• laying blocks of rotary;
• binding vertical seams;
• alignment of walls;
• fishing seams on both sides.

When installing blocks, a concrete solution will be applied. Its thickness should be 2 cm. The laying of the building material is carried out in 4-5 rows. The best clutch of the blocks is achieved by:

• wetting them with water;
• raking solution raking;
• concrete seals in vertical joints.

The cutting depth of the vertical seams of construction depends on the type of soil. On susceptible soils, it is 40% of the height of the block, on swelling, stronger and sedentary soils - 100% of the block height. After mounting the blocks, the horizontal and vertical seams are made.

When erecting blocks that have different lengths, monolithic inserts should be provided. They fill the gaps between blocks. During the work, you need to leave gaps for laying sewer and water pipes, elements of the heating system and electrical cables.

The use of blocks for creating a foundation makes it possible to build houses on any soil with different climatic conditions. They withstand temperature fluctuations in the range from -70ºС to + 50ºС.
