Pile and Pile Retention Wall Design

Pile or Pier Foundations – based on the site geotechnical conditions and the project’s structural and architectural requirements, we analyse and design bored pile, driven pile and screw pile for buildings and other structures’ footing.

Basement Pile Retention Walls – we design a piled wall retention system for a basement, for example, soldier pile wall, secant pile wall and contiguous retention pile wall. Depending on the soil profile and site features, we design anchor supported or cantilevered or waler beam-strut supported basement walls.
