High labor cost: Sandbags need to be pre filled with sand, which requires a lot of manpower and time to complete. The staff need to bend down for a long time to load sand, which is labor-intensive and inefficient.
Heavy weight: difficult to transport: Sandbags increase in weight after being filled with sand, making them difficult to transport, especially in emergency situations, which may delay deployment time.
Environmental impact: After use, sandbags need to be cleaned of sand, which may have a certain impact on the environment, especially in densely populated areas such as cities.
Cost issue: Although the manufacturing cost of sandbags is relatively low, they require frequent replacement and cleaning of sand, which increases the overall cost .
Just due to Above disadvantages of the flood contorl sandbag, noaq boxwall developed flood boxwall in 1996, from below picture you may see, it looks very thin, then how
the thin flood boxwall could prevent flood?
As the flood boxwall adopts a kind of L style principle, it converts the water flow to be pressure to the ground, thus when the flood reaches the flood barrier, the water pressure would press the flood barrier get closer to the ground, that is why flood barrier could stop water and won't fall down.
Just take a easy example, one pc of flood barrier is just about 6kgs, while if you want to stop the same area, you would need to use 50pcs sandbags, from here, you could know
why our flood barrier product could be regarded as a new style flood control product. It is light, easy to take and store, and what is more, it could be repeatedly used for over
7 to 10 years.
And now Denilco successfully invented the second generation flood barrier with fin protection, it well solves the issue that old style flood barrier can't be used in uneven ground. And we have models of 55cm, 60cm and 100 cm high series.
As the most professional flood control product supplier in the world, we are looking forward to serving customers all over the world, and we would continually develop and
invent more useful flood control products.
