Elastocoast is a new type of revetment system for use as a cover layer on dikes. It consists of granular material (rocks), which is fixed together with a two-component polyurethane adhesive. In the Elastocoast system each individual rock is covered with a thin film of polyurethane. When the adhesive is cured, this film fixes the rocks together only on their contact points, creating a highly permeable, open structure. The thesis work actually comprises two separate parts, for which separate reports have been produced. For ARCADIS work was done in the field; two pilot tests with a total area of 875 m2 were constructed and monitored during the storm season of 2007/2008. Parallel to the field work, a desk study was done for the Delft University of Technology, investigating the possible failure mechanisms of an Elastocoast revetment. Findings of this study are presented in a second report. The application of polymers as a binding material in dike revetments is new to the hydraulic engineering community. Design criteria or construction guidelines are therefore not readily available. The purpose of this MSc thesis study is to make a first step in the development of design tools for polymer bond revetments.
