What can the GDB-1 be used for beyond flooding?
Traffic management, motorway and road maintenance, emergency incident protection, crowd control, event management, temporary site separation, and protection of emergency services and work crews.
GDB-1 / Traffic and public safety
A reusable barrier for traffic, crowds and site separation
Beyond emergencies, the GDB-1 can be set up quickly to protect road crews, separate sites and manage crowds — a strong, impact-resistant barrier that is retracted and reused rather than discarded.
Reusable. Telescopic. Made in New Zealand.
Protection for the people doing the work
The GDB-1 is built to take the load of moving water, debris and accidental contact — and not just for water.
Large sections can be deployed within minutes and telescoped to the overall distance you require, then retracted, cleaned and prepared for the next job.
It comes on a trailer, or we build a cradle for a truck to hold and deploy the system.

Common questions
Straight answers about the GDB-1 for traffic and public safety.
Is it suitable for planned works?
Yes. It is suitable for scheduled works as well as unplanned response.
How is the barrier transported?
It comes on a trailer, or we build a cradle for a truck to hold and deploy the system. It is compact to transport and store.
Who is it for?
Transport and roading agencies, construction and civil contractors, ports, airports and logistics facilities, event and venue operators, councils and emergency services are among the organisations the system is built for.
One system. Multiple threats.
The same GDB-1 is configured for other uses too.
Flood and water management
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.

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.
