- It is
essential to fill and lay sandbags correctly. They must not be
over-filled (no more than half to 3/4 full) and when laid, well stamped
down to force the upper bags to mould themselves to the lower bags.
Build up the layers like brickwork with the bottom row butted up tight
to each other, end to end and well stamped down before laying the second
row on top. If the wall is more than two sandbags high, there should be
double line of bottom sandbags, followed by a second double line, then a
single line on top.
- If
you are unable to get ready-made sandbags, you can make your own
sandbags using compost bags, carrier bags or pillowcases filled with
sand or earth. Put a plastic sheet down first to act as an extra
seal.
- When
protecting your home against flooding, all possible water entry points
should be examined and sealed, including airbricks, air vents, and
openings for electricity, gas, and water. If you do seal any gas vents
remember to switch off the gas supply first to prevent the build up of
carbon monoxide gas in your home.
- Seals
around windows and doors should be made watertight, and where advance
preparations are carried out, exterior walls should be protected.
- Waterproof wall sealants can be purchased from builders
merchants, whilst temporary covers for vents may be purchased from
suppliers of flood protection products.
- Remember that airbricks and air vents should only be sealed
during flood conditions.
