Where to use the sandbags?

To bring down the impact of flooding, in most buildings, these bags should be placed over drains and flood wastes. These bags will help with preventing polluted water from entering. These bags should be used in brickwork vents, roller doors or doorways in the front side. Most standard properties on a concrete slab can be safeguarded with less than 25 sandbags. The thing to remember here is that many property owners create sandbag walls during the rainy season to safeguard their property from floods. It is not always essential to place a wall of sandbags around your entire building to safeguard. This type of placement might only be necessary if it is on stumps or constructed with the help of materials like fibro sheeting or timber. Before you build a wall of sandbags, you should first decide on how you would get rid of the floodwater that could turn trapped between the wall of sandbags and your building. For instance, you can use a bailing bucket, siphon or a pump for this purpose.

What are the characteristics of a good sandbag?

In general, for DIY projects, it is recommended that you should use sand to fill the bags and soil is not recommended. In addition, it is also suggested that you should fill the bag only 2/3rd full and you should not dump the bag with sand. Dumping in addition to making the bag hard to carry will also have difficulty in retaining the water. In addition, it is recommended not to tie the top of the bag. Of course, you cannot buy a bag that is not tied, but you can follow the other things when shopping for a sandbag. For instance, make sure that the bags are filled with sand and not soil and also it is better to ensure that the bags are just filled 2/3rd and not entirely and also not lesser.

How to lay a sandbag?

Before you place the bags on the floor, make sure to use plastic sheets for spreading on the floor to act as a waterproofing membrane. Once you place the sheets, lay sandbags like brickwork and begin by placing one over the other from one end to another. Also, make sure that the part of the bag that is not filled with sand is covered by the next bag. At the end of each row, tuck the flap under the bag and make sure to stagger rows in such a way that joints do not line-up.

When you stock-up the sandbag, the thing to remember is that they can rot if you leave them damp and wet. So, storing should be done in a dry place out of the sun. To help you with the selection of the right sandbags, here are some of our best choices:
