Tough tests have shown just how much water a well-known sandless sandbag can keep out of homes and businesses.

And they have proved that just two FloodSax stacked on one another can keep out a foot of water.

More than 2.5 million FloodSax have now been sold worldwide but their success doesn’t mean the stringent tests to push them to their limits ever stop.

FloodSax managing director Richard Bailey said: “We decided to spend a day trying to make the FloodSax fail in different scenarios from standing water to water being forced against them.

“We used the FloodSax to soak up the floodwater to energise them and it showed that each FloodSax expands so much that it will keep out 6 inches of water, making it a foot of water for two FloodSax stacked on top of one another.

“This is the biggest alternative sandbag that we are aware of on the market.”

FloodSax sales director Richard Nikolic added: “We also tested them to soak up internal links and spills and again they more than achieved everything we set out to do.

“It’s well worth taking a day to stand back and test products again just to be certain they are doing everything they are supposed to do. These tests showed why FloodSax remain leaders in their market.”

FloodSax have proved themselves in action worldwide keeping out floodwater from hurricanes, storm surges and flash flooding.

They are also ideal for to have to soak up leaks and spills in homes and businesses, especially those in hard to reach places.

FloodSax are easy to store and deploy. They weigh just 7 ounces before they come into contact with water and can be vacuumed-packed to save even more space.

They are then transformed from being as light as a pillowcase to become better than traditional sandbags in around three minutes.

To do that, all you need to do is add water and watch them miraculously expand.

The semi-porous inner liner within FloodSax contains a special gelling polymer  which absorbs the water to become taut. They are designed so they mould into doorways to keep floodwater out.
