A wall build of black sandbags to protect from flooding

Sandbags And Their Uses

Do Sandbags Really Work?

Sandbags are affordable and available for many people to buy or access which means they are normally the first point of call when there is a potential flood approaching.

As well as being affordable, many suppliers provide them in bulk and often have discounts for higher quantities of sandbags requested. Our webshop offers this.

Whilst they are affordable, the question is, do they actually work?

Sandbags can help to protect your home in case of flooding, but if you purchase your sandbags last minute or empty, they can be extremely time consuming to prepare and put into place. On average, a prepared sandbag can weigh up to 18kg.

If you are just protecting your front door, not many sandbags will be required which means not much time will be required preparing and placing them. But if you are creating a wall, be prepared to spend some time creating a solid structure.

On average, it can take around 600 sandbags to cover a 100ft section at 1ft high. This will require a lot of manual effort for a minimum of two people.

But if you are prepared, sandbags can be an effective way to protect your building from potential flood water.

Sandbags can be kept for up to 8 months after, providing they have not been left in direct sunlight or faced with contaminated flood water which has damaged the bag.  

To conclude, sandbags can provide you with flood protection, providing that you have been prepared and have the time and assistance to place them in time.

 Sandbags and their different uses.

How Long Do Hessian Sandbags Last?

Unlike your typical heavy duty woven polypropylene sandbags which can last up to 2 years, hessian sandbags may only withstand flood protection between 4 and 6 weeks before breaking down and becoming ineffective.

They may not last as long as others, but these sandbags are great to use around livestock or environmental areas.

Once these bags start to break down, they will not cause harm to the environment or wildlife around. They are also difficult for livestock to chew on preventing them from becoming sick.

Hessian sandbags are not only used for flooding, but they can also be seen in military situations or outdoor activities such as paintball, archery and shooting.

Can You Put Wet Sand In Sandbags?

Often when you purchase a bag of sand, it can arrive damp. This is fine to use in your sandbags as it will dry out over time the more you use them.

You cannot use wet sand in them, however, especially not water-logged sand as this will cause your sandbags to be ineffective. Wet sand will rot your sandbags down internally and cause them to become unusable. 


Does The Military Still Use Sandbags?

The military are still using sandbags to this day for many different things during their training and on field exercises.

Sandbags were used on the military field during World War I and provided allied troops with protection in their trenches. To this day, sandbags are still seen throughout the military branches.


Why Do They Use Sandbags In War?

One reason as to why sandbags are used during wartime is for protection against explosions for troops, buildings, or civilians.

Due to the small grains of sand inside and the air bubbles, any explosion will be dispersed, and the shock will be lessened. This is a great way to protect anyone nearby quickly, affordably, and effectively.

Similarly, sandbags can provide troops with adequate shelter during exercises. As well as requiring shelter against opposition firing lines, soldiers may also require shelter against any extreme weather conditions they might be faced with whilst deployed. 6ft-high sandbag walls can provide a certain amount of protection against wind, rain, snow, or sandstorms.

A single sandbag can be capable of stopping a round of bullets protecting troops and civilians behind the wall. When the bullet hits the sandbag, the sand inside is unable to move quickly enough to allow the bullet through, meaning the bullet slows down and stops in its tracks before creating further damage.


How Big Are Military Sandbags?

Your average military sandbag is 75x33cm wide and is often made of hessian fabric. This fabric can act as a great sandbag for the military due it being durable and hardy, along with being biodegradable after a certain amount of time.

Once the troops have moved on and been relocated, the sandbags will start the process of biodegrading and will not damage the environment.


Why Are Sandbags Used In War?

Sandbags have been used in the war for centuries and have been proven to be useful for the safeguarding of both troops and civilians.

From protecting buildings and other important resources, to creating a safe shelter against the extreme weather conditions and the opposition firing line.

They might be a temporary protection for the civilian’s during the war, but they are extremely useful. The sacks and the sand are both cheap and easily accessible which makes the process easier and more efficient to create the barrier.


Why Were Sandbags Used In Trenches?

Sandbags were used in the trenches to protect the soldiers from rifle fire from the opposing side.

Another way sandbags were used in the trenches was similar to how we use them today. Their trenches were not watertight, nor did they have a roof to protect them against the elements. This meant that if  it continuously poured with rain, their trenches would often become flooded which made performing their duties much harder.

Sandbags were laid on the floor to try and absorb most of the rainwater off the floor and prevent the trench from being flooded.


How Do Military Stack Sandbags?

The military often stacked their sandbags 6ft high to provide stability and protection from the harsh weather they could be faced with.

Not only did these sandbags protect the soldiers against the extreme weather they might face, but it also added a level of cover for all their kit. This could include their computers and vehicles, as well as anyone who may be injured.

Along with a 6ft-high wall, they would also stack their sandbags in two rows instead of a single row. This would allow their shelter to be much more stable and reduce the chance of incoming bullets reaching them.  


What Are Sandbags Used For In Plays?

Sandbags are commonly seen acting as cord weights for theatre tracking.

Their structure and weight when filled allows for significant stability of video and sound equipment whilst also posing less risk in the event of a detachment than a purely solid counterweight.


What Are Sandbags Used For In Film?

Sandbags are an essential component in video and film production because they can be used for a variety of purposes.

Primarily, they are intended to give weight to objects such as light stands and grip gear in order to keep them from toppling over and causing injury.
