Lower installation cost compared to that of other currently used systems
‘One-off’ cost only – providing a permanent engineering solution to scour that does not require follow up maintenance or re-application associated with other ‘hard’ methods of protection
Scour is stopped immediately upon installation
Progressive build-up of a permanent fibre-reinforced sandbank
Environmentally acceptable: the sandbank contours follow and blend into the riverbed or seabed, and do not negatively affect marine life, the growth of vegetation, or fishing
Effective in deep or shallow water
Impact damage protection by cushioning structures with energy absorbing sand
Load bearing solution – natural agitation of fronds creates a high degree of sand compaction
Field proven in various locations globally
