Geotextile Encased Columns

Particularly at sites with difficult ground conditions and extremely weak soils or in earthquake regions, reliable ground improvement measures are frequently required to provide a strong base for oil tanks and similar structures. The Ringtrac foundation system takes the form of a regular arrangement of columns comprising noncohesive material placed inside a geosynthetic casing. The structural action of the geotextile casing transforms granular columns into high-capacity loadbearing elements. The columns can be installed more or less independently of the level of lateral support provided by the soft strata to create a ductile structural system. The horizontal reinforcement above the columns, provided by the Stabilenka geotextile woven, facilitates the transmission of structural loads to the columns and promotes global structural stability.

Advantages

  • Adaptability to local conditions and loads
  • Use of locally sourced soils as column fill
  • Almost all settlement takes place within the construction period
