Emergency Repair
Supports rapid filling and temporary protection for flood, bank, and washout damage.
Sack Gabion for Emergency Revetment, Cofferdams, and Irregular Ground
Sack gabions are cylindrical or bag-shaped mesh units that can be filled quickly and placed on uneven, wet, or hard-to-access sites. Their flexible form makes them useful for emergency bank repair, toe protection, and temporary water control.
They can be supplied with suitable mesh, coating, tie wire, and lifting arrangement for flood response, cofferdam reinforcement, channel repair, and underwater placement where rigid boxes are difficult to install.
Product Advantages
- Sack structure: The flexible cylindrical form conforms to uneven ground and supports rapid filling and placement in emergency works.
- Ecological permeability: Stone-filled or open mesh structure supports drainage, pressure release, and ecological recovery.
- Quick filling: The open sack form supports rapid on-site filling and closure for emergency and temporary works.
- Ground conformance: The flexible body follows irregular ground and localized subsidence.
Structure
Sack Gabion is made from flexible woven mesh formed into a bag or cylindrical unit with tied or closed ends. After stone filling, it becomes a deformable protection body for emergency works, cofferdams, toe reinforcement, and irregular terrain protection.
Working Principle
Sack Gabion works by quickly enclosing stone inside a flexible bag-shaped mesh unit. The filled unit can deform to fit irregular ground and hydraulic pressure, making it useful for emergency works. When stacked or placed side by side, the sacks create cofferdams, toe ballast, or scour protection layers.
