One of the varieties of an inexpensive foundation with good bearing capacities is a brick foundation.
This is a fairly inexpensive type of foundation with your own hands, which, subject to the construction technology, may well be used in the construction of houses from a bar or frame, not to mention baths or outbuildings.
A brick foundation can be made of tape or columnar. The names show that the tape is a brick lined tape that runs along the entire perimeter and under the walls of the future building. Columnar, however, involves the placement of buildings on freestanding pillars of brickwork.
Not every brick is suitable for the construction of a good solid foundation with the calculation of its operation for many years. Since brick is the main material used in the construction of this type of foundation, the strength, durability, reliability and bearing capacity of the base of the house depend on its quality.
Facing or sand-lime bricks are not suitable at all, since they are not intended for long-term use and are subject to rapid destruction. Only solid red fired (ceramic) bricks with high frost resistance are suitable for the foundation.
Sometimes a brick foundation is built using materials left over from old masonry.
Although this option will be quite economical, one has to doubt its quality.
Technology erection of a strip foundation made of brick is similar to the construction of a similar reinforced concrete foundation. Here, the same stages of work take place: calculation of the foundation, preparation of the construction site and marking, digging a trench, setting up a sand cushion and erecting the body of the foundation itself.
However, the most basic condition for a brick tape is its high-quality waterproofing. Based on the characteristics of the material used, both the base of the foundation and its outer walls need protection from moisture.
Masonry is made according to all the rules of brick construction. The brick is bonded with mortar. In addition, the strip columnar foundation needs reinforcement.
During construction a columnar foundation made of brick on the construction site in marked places, holes of the required depth are dug. At the bottom of each pit, a sand cushion is arranged and a layer of waterproofing is laid out.
Next, brickwork is made - the construction of columns.
Here, too, waterproofing is necessary not only at the base, but also along all the outer walls of the posts, as well as on top.
If you decide to arrange a columnar brick foundation for a house, then you should remember that the completion of all basic construction work on the construction of a building on such a foundation must be completed before the onset of cold weather. This is important, since the columnar foundation left for the winter can be squeezed out of the soil or it is deformed under the influence of the force of frost heaving and all the work on leveling the supports will go to waste.
This type of foundation is still best suited for a light one-story house, rather than for massive structures.
