Geotextile Encased Columns



what they are:

Columns of granular material confined within high-strength geotextile fabric to increase bearing capacity and provide vertical support in extremely soft soils. They can also expedite consolidation drainage.


how they work:

The columns are installed by driving a close-ended steel casing into the ground, placing a geotextile tube inside of the casing, filling the tube with granular material and then vibrating the steel casing out of the ground.


why you use them:

GECs are used in very soft soils that are too soft for stone columns due to lack of confinement. They provide vertical support, shear resistance and drainage in fine grained soils and can also be used to mitigate liquefaction. Primarily used under embankments and fills.
