What are sandbags made of?
Posted by Sandy Baggs on
Sandbags are bags or sacks that are made of burlap (hessian), polypropylene, or high-density polyethylene. They are filled with sand, gravel, or soil and used for flood control, erosion control, military fortification in bunkers and trenches, or as ballast or counterweight. Sandbags can be used as extra protection for armored vehicles and tanks.
The most common material used to make sandbags is polypropylene, a type of plastic. The polypropylene is thickly woven, with a 10x10 count.
This allows the sandbag's structure to be rugged and last up to 6 months under direct sunlight.
The durable structure helps the sandbag hold up in floods and heavy rain.
