With varying sizes, the containers range from 100 kilograms to over 600 tonnes. The weight provides stability and projects have been designed and constructed in high wave energy coastal areas with waves over 12 meters.
Geosynthetic containers (GSCs) are three-dimensional systems, manufactured from geotextile materials filled with sand. They are not ‘sand bags’ or ‘bulker bags’, but require an engineered approach. GSCs are regarded as innovative, economic and environmentally-friendly systems. They have the added benefit of enhancing marine habitats.
