Our rugged sandbags are made with thick weaves allowing for heavy duty applications like sandbagging, landscaping, construction, and building flood barriers. Featuring a weave count of 10x10, these tough, coarsely-woven sandbags can be used for so many different applications. Made with 1600 hours of UV protection, these sandbags can sit under the sun for six months before they begin to breakdown. We recommend filling sandbags 1/2 to 2/3 full and tie the bag at the top (lay flat when in place). The sandbag should weigh between 35-40 lbs. An overfilled sandbag that weighs between 60-75 lbs may leave gaps that can allow water to seep through. Always wear gloves during filling operation to avoid hand injuries and protect 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. Do not throw sandbags as it may cause stress to the back and shoulders. Rather, use a brigade line to pass bags. Use a short handled, #2 rounded point shovel with straight shaft and D grip, bagger scoop or funnel to fill sandbags. Remove any debris from the areas where the sandbags will be placed. After placing the sandbag, walk on sandbags to create a tight seal between each bag.
