S-Wall®

S-Wall is a drilled pipe pile wall that is mainly used in difficult ground conditions with block-rich ground or other obstacles where sheet piling is not possible. A drilled pipe pile wall is also effective in projects that are sensitive to environmental influences. The S-Wall consists of steel pipe piles connected by a steel interlock, see Figure 1. S-Wall is available in several dimensions. This study is based on the average weight and proportion of each constituent component in one tonne S-Wall.
