Making a foundation out of concrete elements is the fastest option. Although a solid surface is more acceptable for him, for example, filled with concrete, as it is a monolith, it will need to dry for almost a month, and all construction work for this period will be stopped. The foundation of the blocks will allow you to finish everything in one warm season.
Concrete blocks for the foundation, made at the factory, are of fairly high quality. This is due to the production technology, which includes:
- the same and exact composition of the concrete mix;
- rebar tab;
- mechanized pouring of concrete into molds;
- shrinkage of the mixture under the influence of vibrocompression;
- special 8-hour steaming in special chambers;
- final curing of concrete.
You can cast them yourself at home. But for obvious reasons, a number of technological operations will simply be skipped, and the quality will suffer. It will also cost money and time. Modern manufacturing technology at factories gives these blocks one more quality - frost resistance. They obtain this property through the introduction ofcomposition of concrete with special additives. Since the soils in our country are almost universally acidic, crushed granite is introduced into the concrete to counteract the acidic environment.

For the manufacture of the base of the building, two types of blocks are used: wall and cushion.
Wall have cutouts on the sides for good docking with each other. Of these, 2 parts of the base are collected, underground and aboveground. Pillows have a trapezoidal shape. They are used for laying the first row of the base. It is the cushions that ensure the stability of its entire structure.
For those who want to build a foundation with their own hands, ordinary concrete elements are not suitable, as they weigh from 350 to 1400 kg, and their installation requires a lifting mechanism. But for manual laying of the foundation and plinth, they are produced in small sizes, 20x20x40 for the construction of small buildings. They can be made both from ordinary concrete and with expanded clay filler, which has insulation properties. You can not buy expanded clay concrete blocks from your hands, as they may be defective and not have the appropriate strength.
Types of building foundations
For small buildings, such as baths, a columnar foundation is suitable. It can be done in one day.
The strip foundation of blocks is suitable for low-rise small houses made of brick or cinder blocks. It is a tape that is located under all the bearing walls of the building.
Construction of the foundation from blocks of both types includes work on marking them and digging trenches.
The laying technique for both types of foundation is the same and similar to brickwork. All joints and seams must be carefully sealed with mortar. The foundation of blocks for small buildings is quite possible to do on your own. But it is better to use factory concrete elements due to their higher quality.
