Innovative fin type flood barrier. Compared to traditional ones, this new flood barrier has 4 new features: 1. The big advantage is that there is a piece of detachable soft fin-type part(the yellow part in photo), so it can be used on uneven ground. 2. New spring-lock design greatly improved installation speed, as well as better sealing and less leakage. 3. Concave Convex design to joint multiple pieces, better sealing, less leakage. 4. Arch design makes it 25% stronger. Currently we 2 heights available: 55cm and 100cm. To change direction, outward or inward turn pieces are available. These temporary flood boxwalls can build Anti-Flood Wall. Any question, please feel free to contact us.
