Using Big Bags for Flood Control
Coated bags are made with 100% polypropylene offering the same light, yet extremely strong tear resistant security that traditional sandbags offer, but allow emergency crews to use one bag in place of dozens of traditional sandbags. FIBCs used for flood control also have a coating which is a water resistant, and UV protection (much like traditional sandbags) that helps protect the bag from breaking down when exposed to ultraviolet rays such as sunlight. FIBC Silvassa big bags used for flood control/prevention are typically filled with sand, much like traditional sandbags, but can be filled with other substances such as gravel, dirt and other flow-able materials
However, bags on their own can’t completely stop water. Because of the small gaps that remain between the two bags, combining the use of bulk bags with a waterproof membrane OR by filling the gaps between the FIBC with sandbags are two easy ways to complete your watertight barrier.
