Fundamental pillars, as a rule, are made of concrete mixture, made of concrete of asbestos pipes, from metal pipes and ready -made concrete pillars, as well as from praised coniferous logs. In some cases, wells are created under the poles, and sometimes, when using special equipment, the pillars are clogged into the soil without preliminary drilling. One of the most common methods of erecting a columnar foundation is the following: a concrete mixture is poured into dug wells or drilled wells, after which it is filled with a missile stone and intensified by means of metal reinforcement.
