NOAQ Boxwall
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.
