Emergencies develop quickly. Your response must be even faster. The GDB-1 is a multi-purpose flood barrier and defence barrier engineered for rapid deployment in emergency, environmental, infrastructure and public-safety situations.
Thirty-seven seconds, no narration needed. The unit is set down, linked, loaded to its tested flow rate, then lifted out for redeployment — the same sequence a site crew runs.
Set down, apron out — no anchors, no ground works
Units are telescopically deployed to the overall distance you require
Water pushes the face and weighs the apron down
Retract, clean, redeploy — an asset, not a consumable
The barrier in practical testing: set up by hand, held against fast-moving water, and struck by six tonnes of wet clay.
Traditional flood barriers and emergency barriers can require significant labour, heavy equipment, lengthy installation and costly disposal after use.
Our all-in-one system offers a faster and more practical alternative. Large sections can be deployed within minutes, enabling response teams to establish protection quickly while conditions continue to change. Once the incident has passed, the barrier can be retracted, cleaned, transported and prepared for future deployment. It is also compact and easy to store, requiring minimal storage space.
Saving time. Saving lives.
Its rapid-deployment design reduces setup time and labour requirements, allowing emergency teams to respond efficiently without relying on slow, labour-intensive temporary solutions.
Operational simplicity designed in from the start — minimal crew, no heavy plant.
Built to take the load of moving water, debris and accidental contact — and not just for water.
Retracted, cleaned and prepared for the next deployment rather than discarded.
A long-term operational asset, not a single-use consumable.
Efficient footprint in the depot and on the truck, ready to move at short notice. Comes on a trailer, or we build a cradle for a truck to hold and deploy the system.
Specialist material capable of withstanding temperatures of up to 500°C.
Our proprietary defence barrier technology is protected by patent.
Performance and reliability are essential when protecting communities and critical infrastructure. The system has undergone demanding practical testing.
These tests demonstrate the barrier's strength, stability and ability to perform under challenging conditions. Full test documentation is available on request.

Unlike single-purpose flood barriers, the GDB-1 has been developed as a versatile protection system supporting a broad range of applications. It is not just for water: rising and raging floods, land slips and slides, avalanches, sandstorms, traffic management, crowd control and bush fires — protecting valuable assets.
Emergency preparedness is not simply about responding to an incident — it is about having the right protection in place before that incident occurs.
The barrier is designed as a long-term operational asset. Its reusable, low-maintenance construction helps organisations reduce dependence on disposable materials and maintain a system ready for deployment whenever required.
Reduces labour, deployment time and disposal costs across repeated use.
A versatile alternative to holding several single-purpose systems.
Simple to clean and return to a ready state between incidents.
Suitable for scheduled works as well as unplanned response.
A practical, adaptable and cost-effective solution for teams responsible for people, property and essential infrastructure.
Straight answers about the GDB-1 flood barrier — how it compares to sandbags, how it's tested, and what else it can do.
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.
Each unit is a concave A-frame shell. Nested sections are identical profiles offset by plate thickness — not scaled copies — so they telescope out to the distance required, then retract for compact storage and transport.
No. The same system is configured for natural hazards such as landslips and sediment control, for temporary fire-control walls rated to 500°C, and for traffic management, crowd control and site separation.
Practical testing has included exposure to 9–12 cubic metres of fast-moving water per second, a direct impact from six tonnes of wet clay, and static water-retention and containment testing. Full test documentation is available on request.
It carries a 20-year lifespan warranty, subject to terms and conditions, and is designed to be redeployed across many incidents rather than replaced after one use.
