Standards for prefabricated vertical drains (wickdrains)

ISO 12958:1999    Geotextiles and geotextile-related products -- Determination of water flow capacity in their plane
ISO 10319:1993   Geotextiles -- Wide-width tensile test
ISO 11058:1999   Geotextiles and geotextile-related products -- Determination of water permeability characteristics normal to the plane, without load
ISO 12956:1999 Geotextiles and geotextile-related products -- Determination of the characteristic opening size

Below there is a typical datasheet of a wickdrain (prefabricated vertical drain) for soil consolidation. The standards used are listed.
