Sack gabion is a columniform bag woven by double hexagonal netting. When it is used, it's filled with selected stone to make a stable building material with good water permeability to prevent or control flood. At the project site, Sack Gabions are filled with rock to form flexible, permeable, monolithic structures, which is used for emergency and river training works, where local conditions require fast installation or the water does not allow easy access to the site (underwater installations).
