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 BW102 is able to dam 1 meter of water and
is self-anchoring, as it is automatically ballasted by the weight
of the flood water. The higher the water rises, the harder is the
barrier pressed against the ground. Utilizing the weight of the
water, the barrier itself doesn’t need to be heavy. The BW102
”boxes” weigh only 15.2 kg each and the barrier not more than
17 kg per meter. This makes it easy to use, and fast to deploy.
Two people can build 100 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.

There is also a lower Boxwall model, the BW52, which is able
to hold back 50 cm of water (see separate fact sheet).

The boxes are stackable, which means they require very little
space for storage and transport. They are loaded on pallets,
with 32 boxes (29 m) on each pallet. A 40’ container can take
16 such pallets, or in total 460 meters of Boxwall.
