Strengthening and replacing soil layers underneath the foundation.
As the slope is inclined, the foundation bed is placed under different soils conditions, somewhere on the natural surface as well. As a general case, on all foundations, before the throw-in of the weakest layer will be placed a material layer of not less than 20 cm rolled and compacted. The technical parameters of the materials after compression is carried out in cooperation with the geotechnical engineer. Since the foundations are disengaged and the underwater level movement can cause suffusion, it is necessary for the coarse layers to proceed with a geotextile layer that prevents this phenomenon.
