Sandbags

For small water flow protection – up to two feet.

Sandbags can redirect stormwater and debris flows away from homes and other structures if they are correctly filled, placed, and maintained.

Follow the instructions below to maximize the protection that sandbags can provide in floods, hurricanes, and storms of any kind.

Filling:

  • Fill sandbags one-half full.
  • Use sand if readily available; otherwise, use local soil.
  • Fold the top of sandbag down and rest the bag on its folded top.

Placing:

  • Take care in stacking sandbags.
  • Limit placement to three layers unless you have a building or wall to use as a backing. You can also stack sandbags in a pyramid.
  • Tamp each sandbag into place, completing each layer before starting the next layer.
  • Clear a path between buildings for debris flow.
  • Lay a plastic sheet in between the building and the bags to control the flow and prevent water from seeping through openings like sliding glass doors.

Limitations:

  • Sandbags will not seal out water.
  • Sandbags deteriorate when exposed to continued wetting and drying for several months. They may not be effective when needed if they are left outside for too long.
  • Sandbags are for small water flow protection – up to two feet. Protection from more significant water flow requires a more permanent flood prevention system.
  • Wet sandbags are very heavy. Use caution when lifting to avoid injury.
