Absorb, Contain & Divert water
These Quick Dam® flood bags/sandless sandbags absorb, contain & divert problem flood water. Activates when wet, no sand needed. Inner absorbent turns to gel and creates a barrier. Grows to full size in minutes, 12-in x 24-in x 3.5-in high (32 lbs) - stack as needed. Compact, lightweight and quick and easy to deploy. Grows when wet and shrinks while evaporating, so keep reusing for months. Lasts for months, eventually degrading over time. Use indoors or out, best used to divert water outdoors, preventing flood damage. Not for use with salt water, lime or calcium as they cause chemical reaction that deflates bag. Environmentally friendly, non-toxic & non-hazardous.
