How These Sandbags Work

Rainwater and runoff can cause significant damage to unprotected areas. Sandbaggy’s 18” x 30” sandbags act as a barrier that absorbs and redirects water flow, protecting property and infrastructure. For erosion control, the bags’ tight weave and high capacity ensure stability on slopes and embankments.

How to Use

1. Filling: Fill each sandbag halfway to two-thirds full with sand, gravel, or soil. Overfilling may reduce effectiveness.
2. Placement: Place the sandbags in a staggered, brick-like pattern for maximum stability. Walk on filled sandbags to create a tight seal between layers.
3. Storage: Store unused sandbags in a cool, dry place to prolong lifespan.
