Sandbags Filling Tips

  1. Fill sandbags 1/2 to 2/3 full and tie the bag at the top with the included ties
    • Lay flat when in place
    • This sandbag should weigh between 35-40 lbs.
    • An overfilled sandbag weighs between 60-75 lbs and will leave gaps which will allow water to seep through.
  2. Always wear gloves during the filling operation to avoid hand injuries and protect yourself from contaminants in sand and floodwater.
    • Safety goggles should be used on dry and windy days.
    • Filling sandbags is physically demanding work and can easily cause back and other injuries if not careful.
    • Always lift with your legs and not your back.
    • Do not reach out, bend over, or twist when lifting.
  3. Do not throw sandbags - it stresses the back and shoulders.
    • Instead, use a brigade line to pass bags
  4. Use a short handled, #2 rounded point shovel with straight shaft and D grip, bagger scoop or funnel to fill sandbags.
  5. Remove any debris from the areas where the sandbags will be placed.
    • After placing the sandbag, walk on the sandbags to create a tight seal between each bag.

Fill Materials

  • Sandbaggy polypropylene sandbags are built to hold either gravel or sand.
    • Be aware of poor quality sandbags that rupture when filled with sharp gravel rocks.
  • Gravel should be filled in sandbag when used as an erosion control device (on slopes).
  • Sand should be filled for flood control needs, whether to protect doors or garage or to divert water.
  • If sand or gravel is not accessible, less effective solutions is to fill the sandbags with backyard soil.

Which sandbags last the longest?

The longest lasting sandbags will depend on how it's made, such as what materials it's made from, the thickness (how much of the materials were used), as well as any other things added to reinforce the sandbag. Try to get sandbags that are made from high quality materials such as Polypropylene and are reinforced to ensure durability, such as being UV resistant or having extra stitching. Our top of the line sandbag is our Sandbaggy Black Sandbag. The polypropylene fabric is twice as thick compared with standard sandbags and last the longest (9 months - 2 years).

How heavy is a military sandbag?

Military sandbags will vary in weight depending on the size and the weight capacity of the bag. Try to fill your sandbag up to half full as a best practice.

What size are military sandbags?

Military grade sandbags should be around 24" x 14" up to 27" x 16". These size bags are perfect for building earthbag homes.

How long do military sandbags last?

When used for the military, sandbags should be able to last at least the standard 1,600 hours in the sun which is the industry standard. Sandbaggy sandbags last longer though. We tell customers between 6 to 24 months under direct sunlight depending on which part of the country and number of sunny days your location experiences.

Great Sandbags for Truck Bed

The sandbags are working great to add weight in the bed of my truck for winter driving. Thy are much heavier duty than the sandbags you buy at the hardware store.

Sand bags

We like these bags, they're durable and easy to use. We needed something to stop flying projectiles and hopefully these are the ticket. They seem to stack well.

Sandbags Dampen Rooftop A/C Vibrations

Installation of new roofs meant rooftop A/C condensers had to be mounted on stanchions, re new building codes in Florida. This then created a direct channel between vibrating machines and roof underlayment and ceiling joists. Sandbags are being used to dampen vibrations and absorb droning hum. Heavy-duty bags were required due exposure to a tropical sun. This solution is not perfect, but works better than any other ideas brainstormed for this condo association.

Sturdy and well-made

Filled the bags with sand to help break wakes against my bulkhead and they work great! Heavy-duty material and not badly priced. Quick shipping too!
