FloodSax alternative sandbags

FloodSax are a multi-functional and ultra-flexible anti-flood device that can be used both indoors and outside.

FloodSax are best known as alternative sandbags used to prevent floodwater getting into homes and businesses.

They resemble large pillowcases and are vacuum-packed to make them space-saving to store but are quick and easy to deploy.

How they work
When submerged in water the special gelling polymer inside each FloodSax absorbs 20 litres to become an instant ‘sandless’ sandbag in a few minutes. They then weigh around 20kg and have proved themselves in action countless times, saving a fortune in flood damage along with all the trauma and misery flooding causes.

In their dry state FloodSax are ultra-thin and have a large surface area so are ideal to put under drips, leaks and floods inside where they will simply absorb the water to prevent damage. Plumbers use them as they are ideal to deploy in hard-to-reach places such as under floorboards, radiators and boilers.

Flood Sax’s dual use for both inside and outside means you’re prepared for any flooding emergency 24/7.

Many people don’t realise that local authorities have no responsibility to provide sandbags and the Environment Agency warns: “Don’t assume the authorities will provide you with sandbags in a flood emergency. It’s the responsibility of property owners to take appropriate action to protect their property from flooding.”
