Single layer, randomly placed, interlocking concrete units are widely used for the protection of breakwaters. Based on 15 years of experience with Xbloc projects around the world, DMC started the development of an armour unit called XblocPlus. XblocPlus is a single layer concrete unit which is placed in a regular pattern. An essential part of this development were hydraulic model tests in 2D and in 3D to determine the hydraulic stability under wave loading and the overtopping volumes for the new units. These studies and the results regarding the stability, failure mechanisms and roughness coefficient are described in this paper
