Autumn 2014

Calm before the storm

Hurricanes? In the United States they know a thing or two about them. The eastern and southern seaboards of the US in particular have to suffer the consequences when natural disasters such as Sandy and Katrina strike. There is nothing anyone can do to stop them, apart from ensuring that the havoc they wreak is kept to a minimum: the use of TenCate Geotube® technology for example, which can be used to reinforce and raise shorelines sustainably and to build lines of dunes.



The 2014 hurricane season is looming on the horizon, with wind speeds that can reach more than 200 kilometres an hour expected. Many a house-owner in the past has seen dunes and the foundations under their house being swept away. There is, however, a simple, cost-effective and sustainable way of restoring and reinforcing shorelines and dunes: geosynthetics, such as TenCate Geotube®. Geotextile, sand-coloured tubular containers are filled with locally available sand and buried or installed as the core in a line of dunes. Once they are hidden from view, they are ready to break the huge waves that the force of the hurricane pushes up.

A good example is part of the east coast of Florida. The damage that hurricanes caused here more than ten years ago is now a thing of the past. The coastline was restored at the time, the beach between boardwalk (promenade) and sea extended to 50 metres. Whatever hurricane after that ravaged the coast here, the beach and dunes offered sufficient resistance.
