The mechanical consolidation of soil
squeezes free pore water from saturated areas, reduces the volume of soil and

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
