How to use

Manage all water damage and flood events in any situation at a moment's notice. Simply carry to the required location, take out the bag, and soak up the water; in a flood situation us the floodwater to energise the bag and stack as required.

No tools needed: will soak up water, will divert water flow, will work in doorways of all sizes, and can be used to build walls up to 1m high!

Disposing of FloodSax

  • FloodSax are around 96% biodegradable by weight as they are largely water once they have been energised.
  • Ideally slice them open with a knife and tip the insides into a bin to go to landfill. Once they are buried 6ft or more down they should break down and disappear within 2 or 3 months.
  • The outer casing has nylon stitching and the material is a nylon polymer so they are best incinerated.
  • Most of this inner material within a FloodSax – the gelling polymer and wood pulp – is biodegradable so if you want to shrink the FloodSax after use cut across it diagonally from corner to corner with a knife and then pour table salt on the white inners which will break down the polymer.
  • This reduces the size of the FloodSax which can then be thrown into the general waste to go to landfill where most of it will biodegrade over time. If short of time, the FloodSax can be thrown away without cutting it across and adding the salt.
  • Always wear gloves to reduce the risk of contamination.
  • If FloodSax are used on an industrial scale they can be taken to a specialist disposal company which can use industrial equipment to squeeze the water out of the FloodSax.
