The undoubted advantage is the shortest possible time for the construction of the basement, the durability of the structure (up to 150 years, and the piles processed by a special composition will last up to 200 years). There are also disadvantages of this design: great influence on corrosion resistance stray currents in the ground, there may be miscalculations when choosing the diameter of the pile and the thickness of the wall of the trunk of the pipe. Also, in handicraft production, the quality of welded joints is of great importance.
