I may have been a bit harsh Kaz, sorry for that, but this sandbag PR malarkey by politicians, the EA and the media has gone on long enough. They are to blame for creating this hiatus for the scam-merchants to operate in.
Watching the news, reading the papers or listening to the radio people could be forgiven for thinking that a few sandbags can hold back Noah's floods. Sandbags are seen as the universal flood panacea: "Bring in the sandbags and we'll all be saved!"
Nothing could be further from the truth, as this EA leaflet explains:
http://www.southoxon.gov.uk/files/asset ... ea-doc.pdf Maybe this is the advice which should have been given prominence and given out in the run up to the floods.
Do sandbags work?
Traditionally, sandbags have been used to block
doorways, drains and other openings into properties as
well as to weigh-down manhole covers, garden furniture
and to block sink, toilet and bath drains to prevent
water backing up.
• They can keep water out for short periods which
can be improved by using them in conjunction with
plastic sheeting.
• They can filter out some muddy sediments found
in flood waters.
• They are cheap and easy to obtain.
However, sandbags are relatively ineffective when
compared to purpose-designed flood protection
products.
Some of the pitfalls are:
• It takes two people to fill them (unless you have
a sandbag filling machine).
• They take time to fill (approximately one hour to
fill 12 sandbags).
• They can be difficult to handle.
• Laying them can be very time-consuming.
• Sacking material is biodegradable and will perish
if left in place for a long time.
• It is difficult to place sandbags in water and
particularly in running water.
• Sandbags do seep water even when well-stacked
and trodden into place.
As a result, we strongly encourage people to use
purpose made flood protection products, such as
flood boards, non-return valves for plumbing and
air brick covers.
Protecting your property
Sandbags are of no use if your property is already
flooded – concentrate your efforts on protecting
yourself, your belongings and moving precious items
out of harms way!
Consider all entry points that water could get through,
not just doorways, such as – airbricks, utility service
points, cable entry points. Use other solutions for entry
points where sandbags won’t work (such as silicone
sealant).
You’ll need at least 6 sandbags to keep out 20cm depth
of water for a standard door opening. Each sandbag will
need approximately 15kg of sand. You should use
sharp, not soft, sand.
I personally think that it is pretty vile to keep selling people the idea that all will be well if they own a sandbag or two.
