Quick Dam 10ft Water-Activated Flood Barrier — Single Pack, Expands to 3.5" High for Rapid Doorway Protection

Quick Dam Water Activated 10ft Flood Barrier expands on contact with water to absorb, contain and divert flood flow without sandbags.

Quick Dam’s 10-foot water-activated barrier is a compact, lightweight flood control solution that swells into a 3.5-inch high barrier within minutes when exposed to fresh water. Designed for rapid deployment, it eliminates the need to shovel or fill sandbags and can be placed around doors, garages, equipment, or construction sites to help manage unexpected leaks, appliance overflows, or stormwater. The outer fabric resists UV exposure for repeated short-term use, and the internal superabsorbent gel locks in water to form an effective temporary dam.

How quickly will a Quick Dam barrier be ready to block water?

The product begins absorbing immediately and typically reaches full height (about 3.5 inches) within approximately 10 minutes when sufficient fresh water is present. For fast-moving water or stacked protection, pre-soaking speeds activation and reduces the chance of the barrier rolling or shifting.

• Active swelling starts on first contact with water.
• Full 3.5" height in roughly 10 minutes with adequate water.
• Pre-soak recommended for heavy flow or layered use.
• Not suitable for salt water—salt causes loss of expansion.

Where can I use a 10ft Quick Dam and how much water does it absorb?

The 10-foot size is ideal for medium openings like single garage doors, utility room thresholds, and around leaking tanks or appliances. When fully expanded the 10ft barrier absorbs approximately 8 gallons of water, enough to reduce and redirect minor to moderate inflow before it reaches sensitive areas.

• Suited for doorways, garage entrances, basements, and job sites.
• Absorbs about 8 gallons when fully swollen.
• Works for spills, appliance overflows, and fresh-water flooding.
• Compact storage until needed; no heavy lifting required.

How do I position and maintain a Quick Dam to be most effective?

Lay the wider face of the barrier toward incoming water so its wedge design resists rolling and channels flow away from the protected area. For prolonged or repeated use, store dry, keep away from salt exposure, and replace when the internal gel shows wear or fails to expand fully.

• Place wider side facing the water source to prevent rolling.
• Stack or pre-soak for higher flow or extra height.
• Use outdoors or indoors on hard surfaces; avoid salt water environments.
• Dispose in regular trash when no longer functional; non-toxic gel.

What setup steps are required during an emergency?

Simply place the dry barrier across the path of incoming water and allow it to expand. If a surge is imminent, wet the barrier first and then position it to speed activation; no filling, tools, or heavy labor are needed.

• Lay barrier across threshold or in the water’s path.
• Allow 10 minutes to reach working height; pre-soak to accelerate.
• Stack units for taller protection or greater absorption capacity.
• Avoid using with salt water or corrosive chemicals.

Who is this for: Homeowners, contractors, property managers, and first responders who need a fast, portable way to limit water intrusion will find the Quick Dam 10ft barrier useful. It’s best for situations requiring quick deployment around doors, garages, basements, appliances, and temporary worksites where fresh water is the concern and a lightweight, storeable option is preferred over sandbags.
