The Geodesign Barrier system consists of collapsible galvanised steel supports, which are easily opened and locked into a 45-degree position.
The steel supports are placed in the required position and inter-connected using the horizontal connecting rods, which fix the distance between the frames, providing ease of assembly and a high strength construction.
Depending on the model, Aluminium sheets, plywood sheets or pallets are secured to the supports and covered with a waterproof plastic membrane. Chains are used to provide a load onto the membrane until the water arrives. Clips are provided to attach the membrane to the top of the barrier.
The Geodesign Barriers unique design allows the increase of the barriers height during operations to allow for additional flood protection when rivers rise further than expected or maintaining barrier levels in low lying areas.

As the water level rises, it flows onto the waterproof membrane, which extends out from the front of the barrier on the ground. The weight of water on the membrane provides an effective seal against the ground minimising seepage under the barrier.
The pressure of the water on the barrier anchors the supports to the ground due to the inclination of the barrier and a series of collars integrated into the bottom face of the supports. This provides an effective anchoring system, even allowing the barrier to be overtopped.

|The Geodesign Barriers can be assembled in various internal and external corner angles utilising the adjustable connection rods and clip-on Wing-shields, making it a very adaptable barrier system.|
