A sandbag or sand bag is quite simply a sack made either from cotton, nylon or burlap that is filled with sand. Sandbags that need to last a very long time and stand up to just about anything may be made from plastics, particularly polyethylene. When people think of sandbags they usually visualize flooded areas or military bunkers but they have many more real-world uses including, but not limited to, ballast, lighting, tripods, range shooting and signage. People really like them because they are quite easy to transport and deploy, while also being relatively inexpensive and strong.
The most commonly known use for the sandbags is when it comes to the prevention of flooding. This is because they can easily be stacked together, and after stacking the sand that fills the bag will settle forming a solid barrier, with the sandbags acting almost like a type of brick. This is why you would find that in areas that are prone to flooding, people will have a ready stock of sandbags on hand at all times. When it comes to flood prevention, you would most likely want something strong and long-lasting. One of the best sandbags on the market right now is the HD Poly Sandbags which are constructed of black heavy duty tubular woven poly fabric with a double stitched bottom seam and a hemmed top opening. They are EPA compliant BMP for erosion control, boasting four times the life of a standard 1600 hr poly sandbag
In close relation to the flood prevention and water retention properties, the sandbags are at times used to prevent erosion. In many roadway construction sites sandbags are used to ensure that rock and mud do not collapse onto the road. The sandbags for this purpose are usually made from burlap, and it is common for them to be made to sprout ground covers such as grass. This would help in preventing further erosion by creating a solid barrier of plant material. There is no real restrictions on what material you could fill sandbags with, so you could even put fertilizer and seeds in each one which may help further when it comes to environmental restoration.
Another familiar site as mentioned above is military use especially during World War ll, and also during the Korean War where you would find them being used for fortifying military bunkers. The military likes them because they are easy to transport to where they are needed. They are also inexpensive and effective at their task of warding off both water, shrapnel and bullets. A few soldiers, a truck load of sandbags, a shovel and some sand was all it took to make any compound a little safer to be in. Sandbags were ideal for absorbing the heavy impact of attacks by munitions or even the collision of vehicles.
With the rising cost of living everywhere, people are looking for ways and means to be able to reduce this cost, but still maintain a good living standard. If you are person who is also into trying out different techniques for home building, one thing that you could do is use the sandbags to make strong homes that are also well insulated. These homes would be quite cheap to build and also eco-friendly, as they could be made using bags that can be recycled. These sandbags could be used to create walls. To make the sandbags look good, and also be weather tight, you could plaster them, or smear them with any other material available. While you may not find a sandbag house in your neighborhood, these sandbags houses are actually in use throughout the world and especially in impoverished nations as well as for temporary military housing.
Sandbags are also used for ballast. If you would have a load that needs to be balanced such as boats, cars, air balloons or anything else sand bags are a great tool to get the job done. The best thing about them is that if they are no longer needed for ballast you can remove or empty them then store them again for future use.
Believe it or not, sandbags can also be used for fitness training and are actually very common in work-out programs designed for full body work-outs. What makes sandbags an effective training tool is the difficulty of handling them. They’re unstable, unbalanced, and have an odd shape to them. They are about as close to the definition of “dead weight” as you are going to get. There are countless work-out routines that can be found online utilizing sandbags. They also have the added advantage of being stored anywhere you have a small space and they can be emptied and refilled as desired.
