The advantages of the columnar foundation are that it is relatively easy to build, does not require the use of a large volume of materials and, as a result, is a fairly economical construction. The columnar foundation is used in cases where a large load is not supposed to be on the base of the house. In this case, shield and frame buildings, panel buildings of low number of storeys, chopped wood buildings are involved. The construction of a columnar foundation with drilling pits begins. In the corners of the house, as well as at those points where the structural elements intersect, the pillars are installed. In this case, all the heads must be placed at the same level. Between the lower part of the house and earth should be left.
Pillars themselves can be made from various materials. For example, a tree pre -treated with an antiseptic is often used and burnt. But it is better to use brick or reinforced concrete. For better stability and more uniform redistribution of the load, some pillars are bandaged by a grillage. We can say that in many cases such a foundation is a good option for arranging the base of the house. Unfortunately, the column foundation is not calculated on the arrangement of basements. In some cases, it is possible to create a basement, but it must meet some requirements. In particular, the basement must be erected separately from the foundation, so that as a result, a wall can be between the base of the building that can withstand the side pressure of the foundation. Some construction organizations claim that they have the opportunity to build residential facilities based on a columnar foundation with a height of more than three floors. But to trust such firms should not.
