Flood protection is often a matter of time. Traditional sandbag dikes take considerable time and effort to build. Often the time, labour and materials required are not available during a flood event and extensive damage to land and property is the result.
The NOAQ Tube Wall is a quick, lightweight and highly effective alternative to old fashioned dikes. Utilising air and water, the tube wall is a series of interconnected reinforced air-filled tubes. Rather than relying on the weight of the wall itself for anchoring, the NOAQ tube wall utilises the weight of the flood water for a firm seal and excellent anchoring ability.
The NOAQ Tube Wall weighs less than half a percent of a corresponding sandbag barrier and is easily handled by 2 - 4 people. A Tube Wall works as well on lawns and fields as on gravel roads and asphalt and requires minimal site preparation prior to installation.

| The NOAQ Tube Wall is suitable for most flood protection applications but will depend on the terrain of the particular site. Refer to the Checklist in the Download library to ascertain whether a tube wall is applicable for your site.

| The NOAQ Tube Walls come in 10m and 20m sections and are 750mm high. Sections are connected together to create the wall length required to protect the property.

The NOAQ Tube Wall consists of air-filled tubes of reinforced plastic, interconnected to form a chain. A skirt is attached on the flood-side of each tube to anchor the system.
When water starts to rise, the skirt is pressed firmly towards the ground, creating a water seal and a securing mechanism. The tubes are quickly and easily filled using a suitable air blower and just as easily deflated and stored after the flood event has subsided.
The NOAQ Tube Wall was developed in Sweden with the support of the Swedish Rescue Services Agency and has been used successfully during numerous flood events. It has been awarded the SKAPA prize for best inventions in Sweden and in December 2002 it won first prize in BBC´s live ”Best Inventions" show.
