How to prepare with FloodAvert™
FloodBag™ products

Whatever your question about FloodAvert products – we have the answer. If you can’t find it here, simply contact us.

How do you use the FloodAvert Flood Defence system?

Our product boxes and cartons come with a sheet of instructions, and they are also printed on the box. Essentially, our FloodBags are inflated with a source of water and stacked against a backing sheet as you would with sandbags. Our bags can be used at leak points inside the house to absorb water that leaks in (unlike sandbags).

Are FloodBags better than sandbags?

Both can do the same job for external flooding, but with FloodBags you avoid all the effort, stress and mess of getting the sandbags ready for use. In the case of a flash flood, only FloodBags can help – if you have them on the shelf. Only FloodBags can be used inside to soak up leaks too.

What can they be used for?

Keeping water out of homes and businesses, by blocking or diverting flows from natural floods and flash floods. They can also be used in the case of accidental internal floods from failed plumbing, overflows, spills etc.

Will this system help you defend your property?

Our system was designed to stop water entering the main ingress points of homes (doors and low windows) that have a first story – constructed of brick, blockwork or other masonry – on a concrete slab. We can defend weatherboard (wooden or other construction boards) homes that are built on a slab too (using FloodRap).

Our system CAN NOT defend homes on stumps where the water can rise up through the suspended floor i.e., bungalows, Colonial, Queenslanders, etc. In these cases we advise against purchasing our products for natural flood protection – water can’t be diverted in that situation.

What is the orange FloodScreen and FloodRap used for?

These two products have been developed as self-adhering backing sheets, to provide an impervious layer behind the FloodBags, over doors and wider openings (FloodScreen, 3m) and long sections of homes or businesses (FloodRap, 20m).

Where do you get the products?

You can purchase our products online and have them delivered to your door; via an email order; or check retail outlets as they are listed on our website.

How do you choose the products you need?

Our standard sandbag replacement (similar size) is the DefenderBag, and our BoomBag is used to defend wider openings such as sliding doors or garages. Our product range is still expanding and our website will be updated regularly.

How do they come?

Our bags come in boxes of 4 or 5; we also have cartons containing 20 bags. Our bags also come in convenient Tubes, designed to be hung in view so they are always on hand. Simply choose the ratio that would be right to defend your property eg 3 boxes of the DefenderBag (15 bags) and 1 box of the BoomBag (4 bags). We also have Utility Packs that have a mixture of these two bags. Our website shows the product units and what you get in each box or Tube.

How will I get them?

If you buy online, your bags will be posted to your address for the postage indicated at the time of purchase. If you order via email the postage will be calculated and applied on the invoice.

Can they be reused?

Typically, floodwaters tend to be contaminated and local authorities usually advise disposal at designated waste management facilities. In this case they should be disposed of as directed by your local authority.

In the case of mains water flooding eg a plumbing leak or overflow, the bags would not be contaminated. The bags can be split open and the SAP used in gardens or compost heaps. The outer cover can be recycled if cleaned or disposed of as general plastic waste.

How do you dispose of the used products?

Follow the advice of your local authorities regarding disposal of FloodBags, the same as you would with sandbags.

If bags are used to soak up clean water from a plumbing leak they can be split open and the contents used in garden soil or compost; the covers can be recycled or disposed of as plastic waste.

How do you store and care for your FloodBags?

Our bags are wrapped to protect them from moisture and provide indefinite shelf life. Simply store in your garage or cupboard, or on the wall, until a flood warning is issued. Make sure they are accessible at all times.

No other care is required – the bags will remain ready to use at a moments notice.

What are FloodBags made of?

The outer bag is non-woven PP: the contents are paper sheets impregnated with SAP and additional SAP granules.

How heavy are they?

Unactivated bags come flat-packed and weigh between 380g and 390g each. Once activated the bags will absorb up to 20L of water, weighing up to 20kg each. Observe manual handling guidelines when bags are inflated, as printed on the instructions and the box.

What sizes do they come in?

The dimensions of our bags are:

The Defender: 55cm X 45cm (similar to a traditional sandbag)

The Boom Bag: 135cm X 27.5cm

The Diverter: 300cm x 16cm

How are the bags activated?

The SAP granules will start to expand when they come in contact with water. Activating or priming the bags is achieved by pouring on water, from a bucket or hose, or immersing in a bucket or storage bin. Be aware that it will keep absorbing water until it reaches its capacity of approximately 20kg. Partly activating the bags will aid in placement after which they will inflate to full capacity in situ with added water or rising waters.

How long do they last?

Unopened, the bags have a 3 year shelf life.

Why not just use sandbags?

Sandbags require early warning and preparation and transport time: you need to know a flood is coming. Flash floods, from natural or man-made causes, such as burst water mains, occur unannounced.

FloodBags are kept in your home or business for both forseen and unforeseen flooding events. In the case of flood warnings, you will be way ahead of everyone else who will be scrambling to find bags, sand, labour and transport. In the case of a flash flood your FloodBags will be at hand for immediate defence – sandbags will not be an option.

Floodbags give you the luxury of time and save most of the heavy labour and stress of getting sandbags on site to protect your property.

But sandbags are free!

Actually, no – someone pays for each one, via rates, taxes and donations!

True, you don’t pay money for a sandbag: but those that have had to procure their own sandbags already know they are not ‘free’ – they cost in time (which you often don’t have when facing a flood), effort, organisation, stress and exhaustion. FloodBags require none of that: just a simple upfront investment.
