Xbloc Cadzand marina, The Netherlands
The Xbloc and XblocPlus system can be applied as breakwater protection for marinas. In Cadzand, The Netherlands - the new marina is protected by 2 breakwaters equipped with about 4,200 Xbloc units of 1,5 and 4 m3.
Alternatives which we considered for this project were rock armour (size up to 30 tons) and single layer concrete cubes (blocks up to 15m3). The Xbloc system was selected as the blocks could be produced locally and the maximum block size was much smaller than the approximate required cube size. The 3:4 Xbloc slope was steeper than the maximum 2:3 slope for rock and concrete cubes. A steeper slope brought about the following advantages:
