Xbloc is an interlocking armour unit designed to protect breakwaters and shores over the long term and in extreme conditions. This armour unit is a simple, robust and reliable single layer concrete armour unit without reinforcement. It has considerable structural integrity as an individual element and has great hydraulic stability in the armour layer.
Xbloc is the most economical concrete armour unit. The average concrete saving yielded by incorporation of Xbloc units is up to 15 % compared to other single layer armour units. Casting and placing the Xbloc unit is straightforward and is very cost effective. Xbloc has proven to be a very ecofriendly armour unit as the random structure and high porosity of an Xbloc armour layer provide a good habitat for different kinds of marine vegetation and animals.
