The NOAQ Boxwall is a freestanding temporary flood barrier.
It is designed specifically for the urban environment, with even
surfaces like asphalt streets, but it works as well on lawns etc.

A NOAQ Boxwall BW52 is able to dam 50 cm of water and is
self-anchoring. It is automatically ballasted by the own weight
of the flood water. The higher the water rises, the harder the
barrier is pressed firm against the ground. Utilizing the weight
of the water, the barrier itself doesn’t need to be heavy. Individual
”boxes” weigh only 6.2 kg each and the barrier not more
than 6.9 kg per meter. This makes it easy to use, and very fast.
Two people can build 200 linear metres of boxwall in an hour.

A Boxwall is built by snapping the boxes together. No tools are
needed. Gradual curves are made by connecting the boxes at
a slight angle, and for corners there are specific corner boxes.

The Boxwall can also be used during a flash flooding event to
divert water away from vulnerable areas. A number of boxes
are put in the flowing water and will stick directly to the ground.

The boxes are stackable, which means they require very little
space for storage and transport. 26 boxes (23 m) fit on a standard
pallet, and a 40’ container can take 1.1 km of Boxwall.
