Interlocking Concrete Unit-V (ICU-V) has light weight characteristic and developed specifically for mild wave condition. This paper discusses the performance of ICU-V represented by the Stability coefficient, KD and results of the damage progression investigation under different wave conditions. These were achieved by conducting a 2-D physical model investigation by using JONSWAP random wave spectrum. The damage ratio method was used to assess the damage progression. The optimum KD obtained was 12 with highest damage level of 0.4, which is comparable with available armor units. © (2014) Trans Tech Publications, Switzerland. %K Armor; Concretes; Industrial research; Shore protection, Armor unit; Coastal protection; Damage level; Damage progression; Hydraulic stability; Jonswap random waves; Stability coefficient; Wave conditions, Intensive care units
