Sandbag fabric: All you need to know

I What is sandbag and what is its purpose?

A sandbag is a sack made of burlap or woven polypropylene that is filled with sand or soil and used for such purposes as flood control and military fortification. Sand bags are an excellent choice for the construction of levees, berms, dikes and barricades for erosion control, flood walls, and traffic control. Sandbags may be used during emergencies when rivers threaten to over-flood, or a levee or dike is damaged. Quick action and bags on-hand could save countless dollars in personal and property damage.

II When can sandbag be used?

The use of sandbags is a simple, but effective way to prevent or reduce flood water damage. Properly filled and placed sandbags can act as a barrier to divert moving water around, instead of through, buildings. Sandbag construction does not guarantee a water-tight seal, but is satisfactory for use in most situations. Sandbags are also used successfully to prevent overtopping of streams with levees, and for training current flows to specific areas.

Sandbags alone should not be relied on to keep water outside a building. Use baffle boards (plywood sheeting) or sheets of plastic tarp with sandbags. To form a sandbag wall, place bags tightly against one another to form the first layer of defense. Stagger the second and subsequent layers of bags, much like the pattern of bricks in a wall.

Sandbags, when properly filled and placed, will redirect storm and debris flows away from property improvements.

III What are the different types of sandbag fabric.

1 Burlap 

The most commonly used bags for temporary protective barriers are untreated burlap sacks available at feed or hardware stores. Burlap Sandbags have been used by the military and government for many years. They resist all kinds of severe weather and are very useful for flood and traffic control. Burlap bags will eventually rot if not covered or protected from the elements. Empty bags can be stockpiled for emergency use, and will be serviceable for several years, if properly stored.

2 Woven Polypropylene 

When treated for UV exposure, commercial plastic (polypropylene) sandbags are available. They provide the strongest material for flood control, levee, trench and berm construction and all temporary or permanent protective barriers. When covered from ultra violet exposure, Polypropylene Sandbags last almost indefinitely with a minimum of care, but are not biodegradable. Thus they have to be disposed of, or will remain around a long time.

3 QUALITY GUARANTEE: If these sandbags do not live up to your expectations, let us know and we will give you your money back.

V Sandbag limitation

1 Sandbags will not seal out water.

2 Sandbags deteriorate when exposed for several months to continued wetting and drying. If bags are placed too early, they may not be effective when needed.

3 Sandbags are basically for low-flow protection (up to two feet). Protection from high flow requires a permanent type of structure.

4 Sandbags are not always an effective measure in the event of flooding because water will eventually seep through the bags and finer materials like clay may leak out through the seams.
