Vertical drain (for ground improvement)
Terratest

  • vertical drain (for ground improvement) Terratest
Vertical drains have a rectangular cross-section. The core is plastic so that it serves as a channel allowing water to circulate freely. This core is surrounded by a thin filter casing made of a material that acts as a barrier to prevent the soil surrounding the drain from penetrating into the core, while at the same time allowing water in.

Vertical drains can be driven into the ground statically or dynamically. In some very soft soils, water jets with the pipe mouth open or pipe drilling can be used.
