Steel cased driven pile

The driven tube pile with plug is a close ended, low energy driven full-displacement pile with lost steel tube. The pile is formed using an internal free-fall hammer striking a dry concrete plug locked at the bottom of the casing. The tubular segments are welded together in function of the available free working height.

Construction sequence

Fields of application

  • In confined, narrow and difficult to access working areas and/or spaces with restricted headroom

  • In aggressive soil conditions and contaminated soils

  • Suitable in soils with strong underground flow of water, where the fresh concrete is protected by the casing

  • Well-suited for piling through cavities or very soft and unstable top or intermediate layers of soil where overconsumption of concrete is likely to occur.

  • Where the cut-off level is located above the ground level

  • Possibility to maintain with great accuracy the concrete level: execution of non-concreted lengths is possible

  • Wide range: industrial projects, infrastructure, hydraulic engineering works, railway works, housing construction, rehabilitation, renovation…

Environmental impact

  • Limited vibrations

  • Limited noise pollution since driving is performed inside the tube

  • No soil removal (soil displacement pile)

  • A stable, dry and flat work platform is required.
