The best type of sand to use for filling sandbags to protect against flooding is coarse sand. Coarse sand is heavier and more compact, providing better protection against water seepage and erosion.

To protect against 120 mm indirect fire exploding 50 feet away, typically around 8 inches of sandbags filled with wet sand would be required. This is a general guideline and the actual amount needed can vary based on factors such as the trajectory of the projectiles and the specific composition of the sandbags and sand used. Consulting with military or defense experts for a detailed risk assessment is recommended.


What were the sandbags used for in world war 1?

Sandbags were used to build and reinforce protective locations. The flexibility and heaviness of a bag of sand made it easy to stack quickly to create protective barriers. They could stop bullets and shrapnel. They were often stacked against outside walls to provide the additional armor against the enemy fire. The empty bags were easy to carry and could be filled on the spot as one dug trenches and fox holes.


What were sandbags used for World War 1?

The military has used sand bags for many years to absorb shock and projectiles. Sand disipates energy so when a bullet hits it, the shock is spread out among all the grains and the bullet stops.

How to Create Sandbags and Protect Against Floods?

Sandbags are amazingly helpful when it comes to protecting small areas from floods. Sandbags are very easy to create. All you need is sand, polyethylene sheeting, a shovel, a bag for the sand, and wheelbarrows. These are easily available in any hardware supplies store. That’s it! You are now ready to make a sandbag of your own in four easy steps. With the help of another person to hold the bag, fill it with sand. Make sure the bag is only half full and ideally should weigh less than 40lbs. Once the sand is filled, the empty part of the bag should be folded and placed that side down. This will prevent water from seeping in. A single sandbag that leaks can ruin the whole pile. A trench measuring 5 inches deep and 20 inches wide has to be dug around the area that needs to be protected. The polyethylene sheeting has to be laid on the trench and be secured by sandbags that are placed in such a way that they directly face the flowing water. Create new rows only after completing a row as leaving space is not advisable. The best way to build a stack of sandbags is to build it similar to how brick walls are created. This adds more protection to the sandbag wall being built. Normally a three layer stack of sandbags are considered to be sturdy enough and hence sticking to a three layer stack is advisable. That’s all! The sandbags are now ready to protect against flooding. These sandbags can be preserved to use for the following rainy seasons. Enough care has to be taken to ensure that the bags are prevented from repeatedly getting wet. This will give them a longer life span. Also, when not being used the bag has to be emptied and kept aside for use next year. Though sandbags are wonderful at protecting, it must be noted that they are best suited for certain jobs. A two person team will have difficulty protecting a large area. Soil can be a good substitute when sand is not available, and filling the bags with cement will create a more permanent barrier than sandbags.
