Bar Beach, Nigeria
The first phase of the project consisted of a shore protection of 1 km length, armoured by 1.5 m3 Xblocs. This coastal erosion control project solved a long lasting erosion problem that over the past 50 years led to the regression of several hundreds of meters of coastline. The construction started in January 2006. Bar beach is the first Xbloc application in Africa.
First use of the Xbloc special toe unit: Xbase. This modified Xbloc, proves to be a stable solution for the toe construction of an armour layer using any concrete single layer armour unit.
It is anticipated that in future the Xbloc armour will be reused for the shore protection of the Eko Atlantic City project.
