Sandbags can be obtained from any Builders Merchant or DIY Store. But there is nothing special about sandbags - they are simply cloth bags that hold sand or soil so that a low wall can be built to dam the flow of water. If your house is under threat and you have no sandbags you will need to improvise; it is very unlikely that the council or anyone else will be able to provide sandbags quickly enough in a real emergency. Bin liners, pillow cases, seat cushions or plastic carrier bags filled with soil dug from your garden will serve, and so will soil wrapped up in a bath towel made into a roll across the bottom of a door. 'Grow Bags'® are the right shape and light enough to be carried around easily.
