FlexMac is a multicellular Galmac coated corrosion resistant gabion structure with reinforced steel bar integrated into the mesh. Each cell is internally lined with geotextile in which fill can be contained. The unit can be pinned through a spiral connecting interlock.

FlexMac can be lined up, backfilled and stacked up for emergency flood control, coastal protection, bank restoration or simply diversion of water, for both temporary and permanent applications.
