Sandbags have traditionally been made from hessian or jute material. This material meant that sandbags could be filled with sharp sand and used effectively as a flexible tool to make any size or shape of a wall of sandbags. Hessian jute sandbags were ideal for many uses as the material is completely biodegradable and when the sandbags had served their purpose they would naturally rot away and decompose.
Over the years, sand bags have been developed and are now made in other materials for different purposes. Woven polypropylene has seen much development over the years and now millions of sandbags are made using this material. Polypropylene sandbags or “Poly sandbags” are non-biodegradable and so can serve a different purpose. Sometimes sandbags are required to dam a stream or part of a river, in which case, polypropylene sandbags are an ideal solution as they will last longer submerged in water. Extended exposure to sunlight will accelerate the degrading process of woven polypropylene sandbags.
For this reason, heavy duty sandbags have been developed, these bags incorporate a UV stabiliser which helps the material to resist sunlight. However, this does not make heavy duty sandbags indestructible. If the intensity of the sun is very strong, and the heavy duty sandbags are exposed for long periods of time, then the degrading process of the sandbags will still occur. It is always recommended, no matter what you are using your sandbags for, to cover them up with a black or coloured sheet and tuck it in as best you can. This will protect the sandbags by absorbing most of the sunlight and also prevent debris and water from attacking the sandbags.
Recent developments have produced a sandless sandbag (also known as quicksandbag, instant sandbag or inflatable sand bag) where the sand has been replaced by a biodegradable polymer that rapidly absorbs water. Sandless sandbags are supplied in a sealed plastic bag. This allows them to be easily stored flat prior to use. The sandless sandbag is simply immersed in water for 3 - 5 minutes after which the sandless sandbag will be ready to use.
Overall, sandbags are an excellent tool for flood defence, but have to be looked after and used correctly for you to make the most out of your sandbags.

Filled Sandbags are a Must!
Filled sandbags are a necessity in preventing floods, and we recommend to everyone who lives in an area which is at a risk of possible flooding to stock up on filled sandbags. An average household has two doors each of which each will need at least 12 filled sandbags to create an effective flood defence wall. Garages are also vulnerable to flooding. How big is your garage? Please bear in mind that even though an empty sandbag measures 75cm in length, once the sandbag is filled, it will measure approximately 50cm. So if your garage is 3 metres across, you will need 6 x 4 layers of filled sandbags, meaning another 24 filled sandbags will be essential to keep flood water from entering your garage.
This is based on a minimal flood water threat. If the flood waters threat is very high and more severe flooding is expected, be prepared and build the wall of filled sandbags higher and deeper for maximum protection.
You can prepare yourself by going to our online shop and buying your filled sandbags before the floods arrvie. Buy sandbags Now.
How much sand does a sandbag need?
If the sandbags are filled with 25kg of sand, they become more rigid and less flexible therefore making building a wall more of a problem. It may be more difficult to securely position the filled sandbags so it is recommended to fill the sandbag with approximately 15kg of sand. Our filled sandbags are filled with approximately 15kg of sand.
Secondly, if a sandbag is filled with too much sand, gaps may appear in the wall and therefore let more water through when water builds up pressure. Using filled sandbags containing around 15kgs of sand allows the sandbags to be pressed down to make a more effective water barrier.
All of our filled sandbags are filled with 15kg of sharp sand, to enable effective flood defence walls to be built. If you are thinking of buying empty sandbags and filling them yourself, we would strongly recommend that you do not fill the sandbags completely.
