Elastocoast - la protection des digues par BASF

Elastocoast® pour renforcer le littoral
Plus que jamais, il faut trouver des solutions innovantes pour assurer une protection efficace et durable du littoral.
Parmi les solutions proposées, un système élastomère polyuréthanne a été spécialement mis au point par BASF Polyurethanes : l'Elastocoast®. Celui-ci permet de renforcer le revêtement des digues en ballast de pierres concassées.

Elastocoast®: Polyurethane for Coastal Protection
Revetments with Elastocoast® are a new and innovative coastal protection system.
Elastic and porous - these two properties are the secret of Elastocoast®: the ability to yield slightly protects the revetment against the brute force of the water masses crashing down upon them; the interconnecting cavities between the stones absorb their energy. Rigid and solid revetments made from the conventional "adhesives" concrete or asphalt, on the other hand, are often broken down by the pounding force of the waves: starting from an initial, tiny defect, the breakers gradually make deeper and deeper inroads into the revetment.
Elastocoast® with its ecological properties also provides benefits for nature: flora and fauna could find new habitats in the porous structure of the cover layers - and so shore crabs, limpets and beach grass would also stand to gain from this innovation.
The research results speak for themselves, but is coastal protection with Elastocoast® affordable as well? "Cost control was given high priority from the outset in developing the product", says Leberfinger. "Elastocoast® is easy to apply, and because of the reduced thickness of the revetment and the lower cost of the smaller-sized ballast stones, at the end of the day the costs are even somewhat less than those for conventional structures."
