The innovative technology in Coastal Defense

Revetments with Elastocoast are a new and innovative coastal protection system. The term Elastocoast means a bonding system that reinforces hydraulic gravel at their contact surfaces permanently by means of the 2-component plastic polyurethane (PU).

In a joint research project between BASF Polyurethanes GmbH and the TU Hamburg-Harburg (TUHH) the suitability of the use of Elastocoast in coastal protection systems has been proven and the long-lasting stability under environmental influence has been demonstrated. In a further research cooperation with TU Delft and the engineering office ARCADIS (NL), additional tests and dimensioning procedures (GOLFKLAP) for the use of Elastocoast in accordance with international standards has been provided.


Conventional revetments

Revetments are constructions that protect the coastal and shore subsurface against erosion. There are two types of revetments: loose and reinforced.
