Sandbags

In the general scenario, sandbags could come in handy for a number of purposes. First and foremost, it could be used in flood control. Another good benefit about sandbags is the fact that they are very valuable with regards to military fortification, which includes the tasks of shielding glass windows in war zones and ballast. To make a sandbag, one requires burlap (which is an ideal sandbag cover) or some other material, which is easily available. Next after making the sandbag, it is filled with sand or soil, whichever is more conveniently accessible. In short, sandbag construction is not that hard of a task (as sandbag supplies are easily available) and could be easily accomplished, which would later on serve many purposes as mentioned before.

But normally people are more inclined to buy sandbags rather than constructing them or making them on their own. Nowadays sandbag sellers could be found easily. With the development and growing reach of the World Wide Web, sandbags are available online as well. It is just the case of placing the order.

In the case of emergencies, sandbags are very useful tools, especially when it comes to handling situations like floods. They could also be used as water-control structures. One issue of concern about sandbags is the fact that they could not be always be as effective of a measure to control flooding as water has the tendency to seep through the material of the bags. In addition to that, if the bag is filled with finer materials like clay, it could leak out through the seams.

Even for the military, sandbags become a very effective tool. Especially when it comes to establishing field fortifications, sandbag training provides an easy and affordable way to cope with the situation. The sandbags could even be used as a temporary strategy in terms of protecting civilian structures. As usual sandbag supplies (burlap and sand) are cheaper, large barriers of sandbags could be constructed in the affordable range. Explosive blasts could be effectively controlled by sandbags as the friction that results from the movement of the soil as well as the sand grains along with multiple small air gaps does not allow the blasts to continue their flow and fade away somewhere in between the course of their explosion. However there are some factors that need to be taken care of while using sandbags for field fortifications. First and foremost, the dimensions and weight of sandbags should be carefully estimated. This is done particularly so that the bags, which are used, could be intertwined with each other like brickwork and are not too heavy for lifting or moving around. Plain burlap sandbags are not stronger in terms of preventing penetration and deteriorate quickly. In order to avoid this problem, these sandbags are painted with Portland cement slurry in order to reduce the effects of rotting and abrasion. These days sandbags (for the purpose of flood prevention as well as for establishing military field fortifications) are made out of circular woven polypropylene, which is a stronger material than burlap, which was the basic ingredient in the making of sandbags.

As of now, the culture of making sandbags has seen a slight change. That is, these days’ sandbags are filled manually with the help of shovels. It is quite surprising to witness this manual filling of sandbags as the use of machines in filling sandbags had started since the start of the decade of the 1990s. It was a more efficient process and had become common for all kinds of sandbag manufacturers. The comparative analysis of both the manual and the advanced methods of making sandbags have their shares of benefits and disadvantages but the prime factor that goes in the making the making of sandbags (be it manual or with the help of machine) is the factor of suitability. It is in accordance with the demand of the time and the situation that determines which method is more effective. As of now, the manual filling method seems to have taken preference over the machine-filling one.
