HOW TO USE

How to Use

Prepare Sand

Use dry sand or fine soil, free of sharp stones to prevent bag damage.

Fill Sandbags

Fill sandbags to 70-80% full; avoid overfilling to prevent sealing issues or rupture.

Seal Bag Opening

Tighten the polyester drawstring or close the zipper; secure shut and confirm no sand leakage.

Stack Water Barrier

Layer sandbags in a staggered pattern over the flooded area, compact by trampling to create a solid water barrier.

Cleaning and Maintenance After Use

After floods, pour out sand, wash sandbags, dry, fold, and store in a dry location.

Precautions

Do not use sharp tools when filling to avoid puncturing the bag's waterproof layer.

Avoid prolonged exposure to sunlight and contact with grease or chemicals to prevent material degradation.

Store in a dry, ventilated environment to prevent moisture, mold, and damage from rodents and insects.

Do not stack too high; a single layer height of no more than 50 cm is recommended to maintain stability.
