Video about the arrangement of the flood foundation on highly heaving soils. HDPE pipes are selected as permanent formwork. In moments of frost heaving, the earth "slides" on these tubes, and does not raise the foundation. A technical HDPE pipe with a diameter of 16 cm was used. I forgot to mention that sand is poured and rammed between the pipe and the walls of the well ... Water from the well was not pumped out, a thicker solution was made.

Happy viewing everyone.
