An Instant & Ready To Go Flood Barrier!!

Get sandbags installed 10X faster and set up a water barrier in just minutes with Water Activated Sandless Sandbags (also known as instant sandbags or flood bags)! There’s zero work required, once the water hits the sandbag the sandbag expands to create a water barrier and protect against flooding. They work great for flood protection and erosion control applications. They're the ideal size to block doors, protecting your garages, basements, etc.

At Sandbaggy we want to ensure all our sandbags are built to last and able to accomplish just what you need them for! We’ve constructed these 5 ft long sandbags to be extremely tough. They are 2x thicker than the competition and can be dropped 40+ times without any damage to the bag! Plus, they arrive ready to go, and once installed last 3-6 months (they have a storage life of 5 years). Our sandless sandbags are made in the USA.

Also availble in a smaller size: 14" x 26" Water Activated Sandbags.

How do water activated sandbags work? (And how to fill them up)

Our Water Activated Tube Sandbags contain superabsorbent polymers (gel) within the outer shell that expand as they absorb water. This makes them much easier to use and handle than a traditional sandbag. Just dunk these water absorbing bags in a bucket of water, then take them out and spray water on it to fully saturate the bag. When fully expanded they are about 3.5 inches tall. You can easily stack multiple bags on top of eachother.

Do sandless sandbags work?

Sandless sandbags are effective in preventing flooding and erosion, and have been tested and proven to be effective in real-world situations. They work similar to traditional sandbags, the difference is that they use superabsorbent polymers to absorb water and subsequently divert water, rather than being filled with sand, gravel, or dirt.

How long do sandless sandbags last?

Like all sandbags, the lifespan depends on a variety of factors such as the conditions they are being used or stored under. Once activated with water, our sandless sandbags will last 3-6 months. If stored properly, in an enclosed area like a garage, these sandbags have a storage life of 5 years.

Can you reuse water activated sandbags?

Once activated, you can reuse these sandbags as many times as you need within 3-6 months. After that we recommend using a new sandbag.
