Making a Sand-Bag Barrier 

Sandbags can be useful in redirecting storm water and debris flows away from your home. But be sure that the sandbags are properly filled and maintained. Here's how: 

What to Expect  

There are limits to what sandbags can do, so remember: Sandbags will not seal out water. Sandbags deteriorate when exposed to continued wetting and drying for several months. 

If bags are placed too early, they may not be effective when needed. Sandbags are for small water flow protection -- up to two feet. 

Protection from larger flow requires a more permanent flood prevention system. Be sure to consult with your local environmental protection department before disposing of used sandbags. 

Sandbags that are exposed to contaminated floodwaters may pose an environmental hazard and require special handling.
