Swiss Link StormBags Sandless Sandbags

Swiss Link StormBags are water-activated, sandless flood and emergency barriers that expand from 16 oz dry to 33 lbs in 3 to 5 minutes when submerged in freshwater. Each bag measures 23" x 13" and rises from approximately 1" tall when dry to 6" tall when fully hydrated. StormBags are made in the USA and available in 10-pack, 25-pack, and 250-pack quantities.

Ready in Minutes, Not Hours

Traditional sandbags require a supply of sand, shovels, and significant labor before a single barrier is in place. StormBags eliminate that preparation entirely. Submerge a bag in any freshwater source and it reaches full weight and height in 3 to 5 minutes, letting a single person deploy a meaningful barrier before conditions worsen. When the emergency passes, bags that are fully dried can be stored and reused, reducing long-term cost compared to single-use alternatives.

Compact Storage, Serious Capacity

Each StormBag weighs 16 oz dry and lies roughly 1" flat, so a 25-pack stacks into a fraction of the space that pre-filled sandbags would occupy. That compactness matters in a vehicle, a storage shed, or a facility where space is shared with other emergency supplies. The 250-pack option suits property managers, emergency response teams, or anyone who needs volume on hand without dedicating a large footprint to storage.

More Than Flood Control

StormBags absorb and contain water in situations beyond rising floodwaters. A hydrated bag can soak up large spills, plug unwanted openings where water is intruding, or be placed around the base of plants to keep root zones hydrated during drought conditions. The same product serves multiple roles across a property or a vehicle-based emergency kit.

Features

• Water-activated expansion: dry bag submerged in freshwater reaches 33 lbs in 3 to 5 minutes
• No sand required: self-contained polymer absorbs water to form the barrier
• Reusable: fully dried bags can be stored and redeployed
• Made in the USA
• Multiple use cases: flood barriers, spill absorption, gap plugging, plant hydration

Specifications

Who This Is For and Isn't

StormBags suit homeowners, overlanders, and emergency preparedness planners who want a compact, ready-to-deploy flood and water-control barrier without storing sand or pre-filled bags. The 250-pack is sized for facilities, municipalities, or response teams that need volume on hand.

StormBags require freshwater for activation and are not designed for saltwater or chemical-spill containment. Reuse requires complete drying, which takes 2 to 3 weeks in low-humidity conditions and significantly longer in humid climates; bags must not be stored while wet.

Common Questions

What water source activates a StormBag?

StormBags activate when submerged in freshwater. Freshwater is the stated activation method.

How long does activation take?

Each StormBag expands from 16 oz to 33 lbs in 3 to 5 minutes when fully submerged in freshwater, reaching approximately 6" in height from a dry profile of roughly 1".

Can StormBags be reused after deployment?

StormBags can be stored and redeployed once they are completely dried out. In low-humidity environments this takes an average of 2 to 3 weeks; humid climates require longer. Bags should be exposed to sun and turned frequently to speed drying, and must not be stored while still wet.

Which pack size should I choose?

StormBags are available in a 10-pack for light household use or a trial quantity, a 25-pack for a more complete property-level supply, and a 250-pack for facilities, emergency response teams, or anyone who needs high-volume coverage on hand.

Do StormBags work for uses other than flood control?

Beyond flood barriers, StormBags can absorb large spills, plug openings where water is intruding, and be placed around plants to maintain soil moisture during drought conditions.
