ICMS Breakwaters are manufactured in-house to an ISO 9001 accredited quality system. The main function of the breakwaters is to attenuate waves to an acceptable level so that sheltered berthing can be provided where a fixed breakwater is not feasible. Breakwaters also offer client's the option to provide a berthing facility for boats in exposed conditions. The units are manufactured from Grade C50/60 reinforced concrete with internal polystyrene blocks. Given the severe environments that these units have to function in we pay particular emphasis to the enhancement of the lifespan and hence offer galvanised reinforcing steel as standard and as glass fibre reinforced concrete skin to the base of the floatation blocks.
