: The standard for flood control and construction. These are lightweight, water-resistant, and tear-resistant. Look for UV-stabilized versions if they will be outdoors for more than a few weeks; these can last 6–24 months in the sun.
: Best for short-term use, erosion control, or landscaping where you want the bag to eventually biodegrade. They offer a better "grip" when stacked but will rot if left wet for extended periods.
: Used for long-term or permanent ballast and industrial applications due to their extreme weather resistance.
