It takes time to build dikes from sandbags, sometimes so long that you should start work even before it has rained .... Anyone who knows what work is required does not build a dike unnecessarily either, but waits until warnings go out via the media . And then it may already be too late to start. We have developed a mobile protective wall that is so quick to build that you can wait until you know it is needed. In addition, you do not need to have your own army of people carrying sandbags. Since the regular army is probably full elsewhere, it can be safe to know that you can handle the situation on your own. A NOAQ tube wall weighs less than half a percent of the sandbags that would otherwise be needed, and is easily handled by 2 - 4 people. The tube embankment works just as well on lawns and meadows as on gravel or asphalt roads and does not need any preparations or anchoring devices. Namely, it uses the floodwater's own weight as an anchor. A NOAQ tube wall consists of a series of air-filled tubes made of reinforced plastic, which are joined end to end with the help of standard zippers. Each tube has a longitudinally welded jacket that lies against the ground on the "flood side". When the water begins to rise over the mantle, it is pressed firmly against the ground and thus anchors the tube. We call it the "book support principle" because it works in the same way as a regular book support. The book support supports the books, but at the same time is prevented from tipping by the books standing on it. Read more about how the technology works in the information sheet ( PDF). You can also use our checklist ( PDF ) to see if and how the tube embankment could be used in your case. The tub embankment has been developed in Sweden in collaboration with the Swedish Rescue Services Agency and has been used successfully in several floods. It has also won several awards, including The SKAPA prize, which is awarded annually to the best Swedish inventions. In the autumn of 2002, it also won the BBC's live inventors' competition "Best Inventions". The book support principle! © Copyright 2003 NOAQ Flood Protection AB Atellus AB
