NOAQ Tubewall is an air-filled flood barrier which uses the weight of the water and friction to anchor itself.
It consists of a number of air inflated sections (”tubes”) that are interconnected by ordinary zips ties to form a continuous protective barrier.
Each tube is furnished with a skirt which lies on the ground on the flood side. As flood water rises on top of the skirt, the skirt is squeezed against the ground whereby the friction against the ground anchors the skirt and the entire Tubewall. The higher water levels, the better anchoring pressure, and the Tubewall remains stable even if the water rises to the full height of the unit.
When floodwaters have receded, Tubewall units can be deflated and rolled up for later use with no residual water or soil to contend with.
