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.
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.
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.
When the event has passed, the barrier is retracted, cleaned and prepared for future deployment rather than discarded.
Designed to be set up quickly where conditions are changing, and recovered for use at the next site.
Built to take the load of moving water, debris and accidental contact — and not just for water.
A long-term operational asset, not a single-use consumable.
Retracted, cleaned and prepared for the next deployment rather than discarded.
Suitable for scheduled works as well as unplanned response.
Our proprietary defence barrier technology is protected by patent.
Practical testing relevant to slips and sediment has included:
Performance figures are drawn from practical prototype testing. Full test documentation is available on request.
Straight answers about the GDB-1 for natural hazard protection.
The system can be configured to contain mud, silt, clay and debris, and for landslide, rockfall and sediment-management applications. Practical testing has included a direct impact from six tonnes of wet clay.
No. The same system is configured for natural hazards such as landslips and sediment control, for temporary fire-control walls, and for traffic management, crowd control and site separation.
Yes. It is suitable for scheduled works as well as unplanned response.
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.
The same GDB-1 is configured for other uses too.
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.
