How to use sandbags: filling tips and materials

Posted by Sandbaggy Admin on

Sandbags Filling Tips

  1. Fill sandbags 1/2 to 2/3 full and tie the bag at the top (lay flat when in place). This sandbag should weigh between 35-40 lbs. An overfilled sandbag weighs between 60-75 lbs and will leave gaps that will allow water to seep through.
  2. Always wear gloves during filling operation to avoid hand injuries and protect from contaminants in sand and floodwater. Safety goggles should be used on dry and windy days.
  3. Filling sandbags is physically demanding work and can easily cause back and other injuries if not careful. Always lift with your legs and not your back. Do not reach out, bend over, or twist when lifting.
  4. Do not throw sandbags; it stresses the back and shoulders. Rather, use a brigade line to pass bags.
  5. Use a short handled, #2 rounded point shovel with straight shaft and D grip, bagger scoop or funnel to fill sandbags.
  6. Remove any debris from the areas where the sandbags will be placed. After placing the sandbag, walk on sandbags to create a tight seal between each bag.

Fill Materials

  • Sandbaggy sandbags are built for use with both gravel or sand. Be aware of poor quality sandbags that rupture when filled with sharp gravel rocks.
  • Gravel should be filled in the sandbag when it is used as an erosion control device (on slopes) to trap sediment but allow water to permeate. Sand should be filled for flood control needs, whether to protect doors or garages or to divert water. If sand or gravel is not available, a less effective solution is to fill the sandbags with backyard soil.
