The advantages of sandbag alternatives

The flood warnings have been posted,  you are at risk of flooding so what do you do to protect your home or business?  You need to protect the entry points and redirect the flow of water where you can.
Traditionally, sandbags have been used in an attempt to do this.  They are only partially effective and the advantages of sandbag alternatives should render the traditional sandbag a thing of the past.  Modern sandbag alternatives are the way forward. This article explains the different types of sandbag alternatives that are available and their advantages over traditional sandbags.

 

How do sandbag alternatives work?

Some sandbag alternatives are filled with gel. Once laid in position each bag will absorb approximately 20 litres of water and inflate becoming a barrier against flood water. Smaller strips of the sandbag alternative can be used to create a watertight seal around a door and larger strips of the sandbag alternative can be used to direct flood water.
Place them where you need them, wet them to get them to inflate and then they’re ready to protect your property.
Other sandbag alternatives look like flat discs but they fit together to form an effective barrier against flood water wherever you need them. They are excellent for creating a barrier or directing flood water away from vulnerable areas.

 

Why are they better than traditional sandbags?

There are many advantages to using sandbag alternatives.

  • Speed and ease of use: Sandbag alternatives are light and therefore easy to move into the place where you need them. You move them when they are dry which makes them light and easy to handle. Sandbags ideally need two people to fill a them and it is heavy labour.  Many a back has been put out in the process!  Sandbags will then weigh approximately 30 lbs and will be need to be carried or dragged to where you need them.
  • Storage: Sandbag alternatives can be easily stored. The bag type are stored dry and being light can be easily stacked and don’t take up too much room.  The block type are reusable and can be cleaned off, stacked and stored ready for subsequent use. Traditional sandbags however, are the absolute opposite of this.  Large quantities of sand need to be stored, it’s cumbersome, can be messy and takes up a lot of space.
  • Reuse: some sandbag alternatives can be dried and re-used. Traditional sandbags are extremely heavy because they’re full of wet sand.  If you attempt to dry them it is a slow process and often the actual sandbag splits and the wet sand escapes creating mess.
  • Disposal: If the sandbag alternative has been filled with clean safe water then it does not absorb contaminated flood water and can be disposed of safely into the environment. However, traditional sandbags will absorb the flood water, including any contaminants and therefore must be disposed of safely.  There is a tax of £64/ton on disposal of used sandbags on top of the costs of transporting them.  It can work out to be quite expensive!
  • Environmentally friendly: The sandbag alternatives that we supply are filled with environmentally friendly super absorbent material. This means that when the threat of flooding has passed the bag can be split and the contents safely released into the soil for easy disposal.

How Hebden Bridge Flood Volunteers tackled Storm Angus

Hebden Bridge

The Calder Valley in West Yorkshire, is a steep sided valley which reacts very quickly to outbreaks of rain.  The hillside roads become de facto rivers as the water run-off from the surrounding fields and woodland cascades down the roads.

Hebden Bridge, in the Calder Valley, is a renowned flooding hotspot.  The water from the hillside hits the main road at speed, over-shoots the drains and then floods the High Street, damaging both residential and retail property at significant financial and emotional cost.

The Flood Volunteers have taken delivery of some ‘Flexible Flood Defence Blocks’ and have used them most successfully.

 

Flood defence blocks direct flood water into drains

                                                                                                              They have placed them around the drains on the descent roads around Hebden Bridge. They create catchments around the drains, slowing the water and enabling the drains to take the water away, so protecting residential and commercial properties in the town centre.

 

 

 

Storm Angus

During Storm Angus the ‘Flexible Flood Defence Blocks’ were put to good use again.  Various factors were contributing to a potentially dangerous situation: The River Calder was at a really high level; leaves were blocking drains and culverts; and this was in addition to a critical level of water run-off from the hillside.

Flexible Flood Defence Blocks diverting flood water

 

The Flood Volunteers quickly put the ‘Flexible Flood Defence Blocks’ in place and directed the water run-off into a nearby canal. There was a noticeable and immediate reduction of around 80% of the run-off water reaching the High Street.

“Never before has there been such a marked contrast!” said Andrew Entwistle, Flood Warden, Hebden Bridge.

 

Later that day property further up the hillside was under threat. Volunteers armed with 40 ‘Flexible Flood Defence Blocks’ were able to direct the flow of water away from the affected residential property.  Due to the speed with which the Volunteers could direct the water only 2 homes suffered some comparatively minor damage out of the potential 20- 25 houses.

“Thank heaven for the ‘Flexible Defence Blocks’.  In the past, we would have had to fill and carry many, many sandbags over a greater period of time and we would not have been able to save as many homes from damage”

                                                                                                                Another advantage is that after each use, the Flood Volunteers collect up the ‘Flexible Flood Defence Blocks’, clean them with a power washer and then store them away for the next time they’re needed.  They have been reused many times now and are an invaluable tool to the Hebden Bridge Flood Volunteers.

 

“I am delighted to pass on the thanks of the townsfolk.  I’d go so far as to say that the blocks saved the day again! Thank you” Andrew Entwistle, Hebden Bridge, Flood Warden.

The Queen’s Speech – no mention of flooding or homes

This week’s Queen’s Speech outlined a full agenda of bills the government plans to introduce during the next parliament.

Sadly, there was mention of neither addressing the increasing risk from flooding, nor the priority to build new homes.

That says something about the priority the new government is placing on housing.

In their response to the speech, the Director General at the Association of British Insurers, Huw Evans, said:

“It is important steps are taken to provide more affordable homes, which are badly needed by many people. However this needs to be achieved in a sustainable way, within a planning system which is robust about refusing inappropriate development in areas of flood risk and which pays proper attention to advice from the Environment Agency.
Losing your home to flooding is devastating, and repairs costs on average more than £16,500. The threat from flooding remains the UK’s biggest natural risk and consideration of the future impact of climate change must be part of the decision-making process about new housing.”

This is all very well, but there IS an alternative that would allow homes to be built in flood risk areas. That alternative is the provision of sensible flood protection products as part of the building design.  For example, specifying the latest generation of composite flood doors would add less than £1,000 to the cost of the build, but would be a lasting, permanently working defence against flooding.  Other similar provision, such as Smart Air Bricks and Non-Return Valves can be used.

The government and insurers can take steps that will benefit everyone, including the economy, by giving a boost to the flood defence industry in the UK.

Did the March 2015 UK Budget help those at risk of flooding?

In the Budget on 18th March, the Chancellor announced that the government was bringing forward £140m of the £2.3bn six-year flood defence programme. This is clearly good news for the 31,000 homes that will benefit from greater protection, sooner than would otherwise have been the case.

However, as Jon Williams, PwC sustainability and climate change partner, said “With one in six homes in the UK at risk of flooding, clearly more can always be done to accelerate investment, and today’s announcement still only amounts to 10% of the homes at risk gaining protection. Balancing the Government’s overall budget and ongoing austerity measures need to be weighed against the economic losses from flooding, which are only likely to rise as our climate changes.”

Over the next six years more will hopefully be done on the macro scale to protect some of the homes and businesses in the areas worst affected by flooding. In the meantime, many people will be faced with the desperate effects of flooding despite the fact that much of the damage could be avoided with relatively simple measures. What’s more, compared with the devastating impact that flooding can have, the cost of taking such measures is usually quite modest (typically between £1,500 and £9,000).

So why don’t more people at risk from flooding take these measures? We suspect much of it is complacency. Like so many other areas in our lives, people just don’t believe it will happen to them.

It would of course have helped if local authorities had been able to get the message about Repair and Renew Grants to more of those who were affected by the flooding in December 2013.  Much of the money that was allocated for the grants has not been spent.

We have heard that some authorities have extended the deadline beyond March 2015, so if you were flooded between 1st April 2013 and 31st March 2014, it would be worth approaching your local authority to ask whether you can still submit a claim.
