Quick Dam Flood Bags Frequently Asked Questions

What are Flood Bags Used for?

Flood Bags are designed to absorb, block, and redirect water during flooding or heavy rain. They are commonly used to protect doorways, garages, basements, and property perimeters from water intrusion.

How do Flood Bags Work?

Flood Bags activate when they come into contact with water. The inner absorbent material expands quickly, turning the bag into a heavy, water-filled barrier that helps stop and control water flow.

Where Should Flood Bags be used?

Flood Bags are ideal for both residential and commercial flood protection, including:

  • Doorways and garage openings
  • Basements and foundations
  • Around equipment or inventory
  • Along property edges to divert water

Are Flood Bags Better than Traditional Sandbags?

Yes—Flood Bags offer several advantages over traditional sandbags:

  • No sand or labor required
  • Lightweight and compact before use
  • Faster deployment in emergencies
  • Cleaner and easier to dispose of

Why can't Flood Bags be used with Salt Water?

Flood Bags are filled with a super-absorbent polymer that reacts best with fresh water. When exposed to salt water, the minerals interfere with the absorption process, preventing the bags from expanding properly and reducing their effectiveness. For best performance, Flood Bags should only be used with fresh water from rain, leaks, or flooding.

Why Choose Quick Dam Flood Bags?

Flood Bags provide flexible water protection wherever water appears

Water activated flood bags provide fast, reliable flood protection without the mess of traditional sandbags. These sandless sandbags absorb water and expand within minutes, growing to 12" x 24" x 3.5" and absorbing up to 4 gallons of water to help block, divert, and control flooding. Designed for flood control and storm protection, the flexible bags can be stacked, curved, or positioned to create an effective flood barrier around doorways, garages, basements, and low areas. Because no sand or filling is required, water activated flood bags are cleaner, lighter, and much easier to deploy during an emergency. Compact and lightweight before use, these flood protection bags are easy to store and keep on hand for storm flooding, water leaks, and emergency flood control.
