A sandbag is a bag that is filled with sand and other materials and tied shut to prevent the contents from coming out.
Originally, they were civil engineering materials used for emergency measures in the event of flooding and at civil engineering sites, but they are also used as agricultural materials because of their strength and durability.
Sandbags are used for a variety of purposes in agriculture. Sandbags filled with sand and other materials are used to hold back water in rice paddies to make them waterlogged, or to remove the sandbags for drainage.
They are also used to repair and reinforce agricultural waterways. Because they are strong and lightweight, sandbags can also be used simply as bags for harvesting vegetables, garbage, tools, etc. Hemp sandbags are also highly breathable and can be used as storage bags for potatoes, onions, rice, etc.
In addition, they can be used to grow vegetables and flowers by drilling drainage holes in them and filling them with soil.
Hemp sandbags are characterized by their high air permeability. In the past, hemp sandbags were commonly used, but nowadays, polyethylene sandbags are the most common type.
They can be used for various purposes, such as bag cultivation, storage of gardening tools, and preservation of root vegetables. They can be used for a variety of purposes.
The majority of sandbags currently in circulation are made of polyethylene. Polyethylene bags are lightweight and often less expensive than linen bags, making them useful when preparing large quantities.
One disadvantage of polyethylene is that it is susceptible to ultraviolet rays. For long-term use in sunny locations, it is effective to use black sandbags with an anti-ultraviolet deterioration agent.
The size of a sandbag is commonly 20 to 25 inches, which is easy for people to carry. This is to ensure that the sandbags are of uniform size so that they can be stacked without gaps in case of flooding, thereby effectively preventing flooding.
The standard capacity when filled with sand is approximately 55 lb and sandbags with line at the 55 lb mark are also available. In addition to the standard size sandbags, there are also larger sizes for transporting heavy machinery and smaller sizes for gardening.
Choosing the right type of sandbags is very important for the effective use of sandbags. Select the appropriate sandbags based on its features and size.
Sandbags are primarily used to hold back water, but they can be used in a variety of ways depending on how they are used. For example, hemp sandbags, which have excellent air permeability, can be used to grow vegetables, fruits, and flowers in bags.
The caveat to this use is that polyethylene sandbags, which are sensitive to ultraviolet light, are generally not acceptable, since adequate sunlight is essential for plant cultivation. When growing plants in sandbags, it is appropriate to use hemp sandbags or UV-resistant polyethylene sandbags.
In addition to bag cultivation, sandbags can also be used as storage bags for potatoes and other items or for storing tools.
Although sandbags are widely used as agricultural materials, their durability makes them difficult to install for long periods of time, and they are prone to water leakage through gaps, which can be a disadvantage.
In addition, the more sandbags are used, the more physical strength is required to install them. It is important to use the appropriate type of sandbags according to the purpose of use.
Sediment is indispensable for making sandbags, but in some areas, it may be difficult to obtain sandbags. In such cases, water-absorbent sandbags are recommended.
Specifically, the bags can be used just like conventional sandbags by soaking them in water and allowing them to expand. This type of sandbags is characterized by its lighter weight after water absorption than sandbags filled with sediment, making it convenient for transporting after water absorption.
They can also be used simply by soaking them in water as needed. Since they can be stored compactly before use, they can also be used as household disaster prevention goods in areas where flooding is expected.
