 Wedge Barrier – Self-deploying flood barrier and spill containment

The Wedge Barrier is a rapid, self-deploying flood barrier that is activated using the weight of the water. Ideal for flood control, blocking streams and other waterways to create reservoirs, as well as containing toxic spills – a special model is available for petrochemicals – the unique design of the Wedge Barrier allows water to flow inside for automatic deployment and self-stabilisation.


Suitable for any surface, sections are easily joined using Velcro and the Wedge flood barrier will curve to any given angle due to the flexibility of its design. Able to withstand very cold temperatures, the Wedge Barrier can resist ice and is usable as low as -40°C.


Wedge Barrier benefits:

  • Suitable for flooding, reservoir creation and spill containment
  • Self-deploying and easy to join
  • Installed on any surface
  • Usable in extremely cold temperatures



Pivot Barrier

The Pivot Barrier provides flood defence over dead-level thresholds for vehicle or forklift access. The Pivot Barrier is controlled using precision gas assist lifting for effortless opening, closing and rapid deployment with single point locking.


Made from maintenance free aluminium panels, installation is simple, with no excavation required. The Pivot Barrier can be ground or wall mounted, internally or externally over any flat impervious surface, with flood widths up to 4.25m and heights of 700mm.

...brilliant, they have worked really hard to get out plant back running and nothing has been too much trouble...they are a credit to your company. I wish we had a shift full of them, we would have them back on our sites anytime.

I would like you to pass my thanks to your response team(s) and particularly the individual who attended the port so promptly on Monday early am. They acted in a thoroughly professional way, they were of great assistance and always helpful. They are a credit to Adler and Allan and I look forward to us working together for our mutual benefit in the future.
