Dike and Coast Protector


Elastocoast is a bonding system that reinforces hydraulic gravel at their contact surfaces permanently by means of the two-component plastic polyurethane (PU). These coverings protect dikes by absorbing the force of breaking waves and slow down the water masses.


Elastocoast is porous for better wave absorption


This environmentally compatible material sticks the hydraulic gravel together, resulting in a monolithic, three-dimensional and stable structure. The small amount of PU used ensures that the structure remains completely porous and the wave impact is far better absorbed. The result: a reduced wave run-up and a decreased potential for damage.


Furthermore, this new technology is more cost effective as a substantial amount of construction material is saved due to the high resistibility of the PU. Elastocoast consists of approximately 50% renewable raw materials and was nominated for the BIOPLASTICS Award 2007 of the European Plastics News. Successfully realized reference projects performed on a total area of about 15,000 m2 shows that revetments reinforced with Elastocoast provide a fully approved alternative in the field of coastal protection constructions, and that Elastocoast is on the right track to become an established technology.


The developments of new revetment systems are subject to various requirements. These requirements refer to the resistance against hydraulic impact but also to various interactions in the natural environment. In addition to the permanent attack of weathering, aspects of neutrality with regard to ecological toxicity or visual integration into the landscape are also very important.
