Background information

There are two basic approaches to dealing with flooding events:

  • Flood Resilience - to let the water in, but ensure the property is capable of being made habitable/usable again very quickly, or
  • Flood Resistance - not letting the water (and what it usually contains!) in the first place.

The HiBar system is quite specifically in the second category, because we feel that most property occupiers or owners do not want the inconvenience of moving out at all, let alone have the thought of what the floodwaters have carried in (raw sewerage, vermin and other chemical contaminants such as diesel and petrol from flooded vehicles and filling stations). For business owners, the cost of business interruption can be calamitous, especially in tight general economic/trading conditions.

The contamination aspect led to some householders not being allowed back into their houses for up to 18 months (such as Carlisle in 2004 and Tewkesbury in 2007). Some were in Bed & Breakfast accommodation - some in caravans in the front gardens - neither an attractive alternative.

A little known fact is that, due to such contamination risk, sandbags should only be used once, and then should be put into landfill sites, but how many times do we see piles of them stacked neatly against a gatepost for use time and time again. They become home to an ever-accumulating cocktail of toxins and bacteria, ready to be washed out again in the next flood.

Door/window panels and airbrick covers are readily available and are seen as a cheap alternative, but these rely upon the waterproof and strength qualities of the surrounding brickwork. Water under pressure does not need a very big crack to find its way into a property.

Flood protection

Finally, demountable systems that are set away from the property (notably the pallet barrier system) have been employed successfully in Ironbridge, Worcester and Upton on Severn on several occasions since 2000. The latter two had incidents of the barrier being circumvented and (in the case of Upton in 2007) not being able to be transported to the site in time, due to flooded access roads.
