It only held back 1,912 milliliters. Because of the results of this experiment, I wonder if something solid like concrete, steel or metal would work as well or better. Also, I think that the more compacted the material is, the better it works. I would run a more accurate flood, make bigger sandbags, make a more waterproof flood table, run the test longer, make sure that all sandbags are the exact same size, and many more. Many thousands of people and homes have been killed or injured in floods.
Sandbags help to prevent floods from damaging homes.
They also help save peoples lives. A properly built sandbag dike can reduce or prevent flood damage. To make a dike 1-foot high, you need to use 800 sandbags. When filling them make sure and fill them only half way full. When deciding to make a sandbag dike you should place it in a place where it has all the natural advantages.
