Floods develop quickly. The GDB-1 is a telescopic flood barrier made in New Zealand, set down and linked on site to hold back rising water or divert fast-moving floodwater — then retracted, cleaned and reused.
Sandbags are single-use, labour-intensive to fill and place, and have to be disposed of afterwards. Traditional flood barriers and emergency barriers can also require significant labour, heavy equipment and lengthy installation.
The GDB-1 is set down with its apron out — no anchors, no ground works — and units are telescopically deployed to the overall distance you require. Water pushes the face and weighs the apron down. Large sections can be deployed within minutes, while conditions are still changing.
Once the incident has passed, the barrier is retracted, cleaned, transported and prepared for future deployment. It comes on a trailer, or we build a cradle for a truck to hold and deploy the system.
A rapid-deployment design reduces setup time and labour requirements, so response teams can establish protection without relying on slow, labour-intensive temporary solutions.
Operational simplicity designed in from the start — minimal crew, no heavy plant.
Retracted, cleaned and prepared for the next deployment rather than discarded.
Efficient footprint in the depot and on the truck, ready to move at short notice.
Reduces labour, deployment time and disposal costs across repeated use.
Our proprietary defence barrier technology is protected by patent.
Performance and reliability are essential when protecting communities and critical infrastructure. For flood use, practical testing has included:
Performance figures are drawn from practical prototype testing. Full test documentation is available on request.
Straight answers about the GDB-1 for flood and water management.
Sandbags are single-use, labour-intensive to fill and place, and have to be disposed of afterwards. The GDB-1 is set down, linked and loaded in minutes, then retracted, cleaned and stored for the next incident.
Large sections can be deployed within minutes, enabling response teams to establish protection quickly while conditions continue to change.
Yes. It is retracted, cleaned and prepared for future deployment rather than discarded, and carries a 20-year lifespan warranty, subject to terms and conditions.
It is built for organisations that protect communities: councils and local authorities, Civil Defence and emergency management, fire and emergency services, infrastructure and utility providers, construction and civil contractors, farms and rural properties, and communities exposed to flooding.
The same GDB-1 is configured for other uses too.
The same GDB-1 system used for floodwater can be configured to contain mud, silt, clay and debris, and for landslip, rockfall, avalanche and sandstorm applications.
