Is one of the most profitable in the cost of the types of foundation. It is used mainly during the construction of small buildings without a basement, since the space between the Earth and the house should be closed – this helps to reduce heat loss. However, in this case, the space should be ventilated, otherwise dampness will accumulate under the building all the time. What is a columnar foundation? At a certain distance from each other around the perimeter of the buildings, wells are drilled, which are subsequently filled with concrete and vertically reinforced with several related rods of reinforcement.
The supports should first be installed at the corners of the future structure, at the intersection of walls and throughout their length. It should be noted that a certain interval between the supports must be observed. This type of foundation is quite acceptable for construction on the ground with heaving soil and a deep level of freezing. The columnar foundation has several varieties: brownish and screw piles, as well as wooden and pantries. To date, the most demand is the brownish and screw piles, perfectly suitable in cases where the supporting layer of soil is quite deep. In order to make brownish piles, you need to drill wells, then install the formwork, which makes the lower part of a wider. It is this geometric feature that helps reduce the likelihood of pushing piles in the process of soil tuning. Then the vertical and horizontal reinforcement should be laid and concrete pour into the formwork. In this case, the columns are displayed to the desired height and after that you can already put the house on top – not a very heavy frame or wooden structure.
After building a house, you will need compressors. One of the most popular compressors is AirCast compressors, which can be a decent choice.
