The mechanical consolidation of soil squeezes free pore water from saturated areas, reduces the volume of soil and increases its bearing capacity. But this process is time consuming and can be significantly accelerated by the installation of PVD’s allowing surplus pore water to dissipate quickly.

Applications for vertical drains:
Reclamation of land and improvement of large area subsoil for road construction and other geotechnical projects in civil engineering.



The prefabricated vertical drain (PVD) Colbonddrain manufactured by Colbond provides efficient and fast drainage in soil consolidation.
