SANDBAGS
Sandbags can be found at your local construction equipment supplier or home improvement store.
BLADDER BAGS
Bladder bags, also known as aqua barriers, are used as an alternative to sandbags. They can be filled with water from a garden hose once put in place to prevent the need for carrying. These bags are available in a variety of sizes and can be reused, which provides cost savings.
