The NOAQ Boxwall is able to dam 0.5m of water and is extremely lightweight and easy to deploy. Although the weight of each box section is light, at only 6.2kg, the Boxwall stands firm without any external fastening, even when damming water to its full height. The Boxwall flood barrier is anchored by the weight of the flood water itself.
The Boxwall is particularly useful during flash flooding to control fast flowing water, diverting it away from vulnerable entrances. The Boxwall sections simple stick with the asphalt and divert the water.
