Sandbags prove invaluable for fortifying walls, shoring up levees, or safeguarding against floods. Opt for specialized bags designed for this purpose and select dense sand to prevent leakage. To fill, fold the bag's top to create a collar, then carefully pour sand using a round shovel. Secure the bag with a drawstring or by folding if used for wall construction. Enlisting help is advisable due to the challenge of holding the bag open while pouring sand.
Preparation Steps
Material Selection and Preparation
Procure polypropylene bags specifically crafted for sandbagging. Avoid standard cloth or plastic bags as they are prone to tearing when wet. Opt for woven polypropylene bags designed for stacking and water resistance, available at construction supply stores or online. Optimal dimensions range from 14–18 inches wide and 30–36 inches deep. Consider bags with built-in drawstrings for easier tying, although tying isn't necessary for flood walls.
Choose a dense sand or soil blend for filling your bags.
Pro Tip: Beach sand is often too fine and will seep through sandbags due to its texture.
Recruit assistance to streamline the sandbag filling process.
Don protective gear including gloves, boots, and eyewear.
Preparing to Fill Bags
Fold the bag's top 2-3 times to form a sturdy collar.
Handy Hint: When working with others, have one person hold the collar open for easier sand pouring.
Scoop sand into the bag's opening using a rounded shovel.
Cease filling when the bag is 2/3 full to ease tying or folding.
Securing the Bags
Open up the collar and raise the top of the bag.
Secure bags with built-in ties by tightening the drawstring.
Pro Tip: There's no strict rule for tying sandbags with drawstrings; a secure knot is what matters.
Use the bag's fabric to tie it if it lacks a drawstring.
Fold the bag's top over itself when constructing a wall.
Useful Tips
- An emergency flood wall should ideally be 5 feet (1.5 m) tall. If it exceeds this height, utilize multiple columns to prevent collapse.
- Consider straw bales as an alternative to sandbags for water resistance. When wet, straw bales expand, impeding water flow and serving as effective flood barriers.
Warnings
- When relocating sandbags, prioritize lifting with your legs to avoid back strain and potential injury.
