A sandless flood bag is a flat pack that swells when it is soaked in water, as a lightweight alternative to sandbags. A 20 litre version is about 540 x 450 mm.

They are stored dry and flat, so a household can keep a few in a cupboard. Flood bags help slow minor surface water at a doorway; they are not a flood defence and do not stop rising or deep flood water.

Key features

  • Stored dry and flat
  • Swells with water
  • About 20 litre bag, 540 x 450 mm
  • No sand needed
  • Light to store
  • Good for minor surface water

How to use it

You soak the flat bag in water so it swells, then place it across a doorway to slow minor surface water.

  1. Take the bags from storage and clear the doorway of debris.
  2. Soak each bag in clean water, following the pack instructions, until it swells.
  3. Place the first bag tight against the base of the door or gap.
  4. Lay further bags end to end, with no gaps, and press them together.
  5. Stack a second layer offset over the first if you need more height.
  6. After use, let them dry as the instructions say, and dispose of them according to local rules.
Tips
  • Store them dry and flat in a cupboard, so you have them ready.
  • Move vehicles and valuables upstairs, as the bags only slow minor surface water.
  • Do this before the water arrives, not once it is flowing.
Safety and limits
  • They are not a flood defence and do not stop rising or deep flood water.
  • Do not wade through flood water, which can hide hazards and contamination, and keep away from electrics.
  • Wet bags are heavy, so lift with care.
Please note
  • Does not stop rising or deep flood water; follow official flood guidance
  • Single use once soaked
  • Contents are a gel or polymer; do not dispose of in drains
