Repellens Flood Barriers – Automatic Property Flood Resilience by Protectology Ltd
Geoff. Evans BSc CEng MICE
As a chartered flood risk Engineer with over 20 years’ experience, I often wondered why conventional domestic flood barriers must be stored, installed, and then demounted after flooding.
After all, most victims of flooding are unprepared and are caught out by the shortness of time to prepare or absent from the property.
Those who are elderly or infirm often being totally reliable on others to help…if indeed ‘others’ are available…
At Protectology we have developed the Repellens range of patented automatic flood barriers to overcome this problem. They are unobtrusive and durable buoyant structures that deploy automatically in response to surface water or groundwater flooding. They suit both the commercial and domestic markets.
As Innovators, we are now offering this as an exciting business opportunity, by inviting expressions of interest from organisations wishing to commercialise this unique system under licence.
- Rising like a drawbridge they tip to the vertical, closing onto a seal before the water level reaches the defence threshold. Thereafter, on-seating water pressure ensures a tighter seal. After flooding the barrier drops onto the cushion of water before settling back safely into its housing, as the water drains away.
- No electrical, mechanical, or manual intervention is required. Power failures often occur during flooding, mechanisms become jammed and people are not always there.
- The illustrations left and centre below show the domestic barriers before and during flooding. They are easy to install to new build or retro-fit to existing properties. Normally unobtrusive, they are designed to operate reliably, even without regular cleaning. Massive buoyancy overcomes the build-up of grit and grime in normal use.
- The illustration to the right below shows the commercial barrier. The vehicle deck allows passage of heavy goods vehicles over a waterway or drainage channel. In public areas suitable hazard warnings, such as those at a level crossing, are required.
- We have Yorkshire based Crompton Mouldings on stand-by as manufacturers and the British Standards Institution at the ready to obtain Kitemark approval.
