Sand bags are a reliable, low-tech solution for erosion control, flood defense, and jobsite stability. In building and landscaping projects they help direct stormwater, stabilize slopes, prevent sediment runoff, and create temporary barriers or cofferdams. They also serve as ballast for signs, scaffolding, tents, and traffic control, making sandbags a smart addition to your site safety and stormwater management plan.

Choose the right construction for your needs. Woven polypropylene sand bags are durable, UV-treated for outdoor exposure, and resist rot and mildew. Burlap sand bags biodegrade naturally and are favored for landscaping or short-term sediment control. Common sizes include 14x26 inches for standard flood control and 18x30 inches for higher capacity. Look for integrated tie strings, reinforced seams, double-stitched bottoms, and UV ratings. Decide between empty sand bags for on-site filling or prefilled sandbags for rapid deployment.

Benefits you’ll notice on the ground:
- Fast to stage and stack for flood barriers and erosion control.
- Cost-effective protection for foundations, doorways, and trenches.
- Conforms to uneven terrain and holds shape under load.
- Available in high-visibility colors for traffic and work zones.

Selection tips:
- Application: flood control, trenching, slope stabilization, or ballast.
- Material: polypropylene for longevity; burlap for biodegradable needs.
- Fill: clean sand for dense barriers; pea gravel for drainage.
- Closure: integrated ties or heat-sealed options.
- Visibility: orange or yellow for traffic safety; green or white for landscaping.

Usage best practices:
- Fill each bag 1/2 to 2/3 full (about 30–40 lb) to allow proper stacking.
- Fold the top under, lay bags in a staggered “brick” pattern, and tamp flat.
- Pair with plastic sheeting for a tighter water seal at doorways and foundations.
- Store out of direct sunlight to extend life; follow local guidelines for disposal, especially if bags contact contaminated water.

Accessories like sandbag fillers, stands, funnels, and palletized bulk packs help speed deployment and reduce labor. Looking for flood control sandbags, erosion control bags, or sediment management solutions? Start here.
