Levvel-bloc

Levvel-bloc is the name under which the innovative XblocPlus block is applied on the Afsluitdijk Project in The Netherlands.

The Afsluitdijk, which is the first project where XblocPlus is applied, is constructed by the Levvel Consortium which consists of BAM, Van Oord and Rebel. During the tender for the project it was decided to apply XblocPlus within the Afsluitdijk Project under the name Levvel-bloc, named after the consortium. On the Afsluitdijk Project, the use of the blocks provides a reduction in concrete quantity and CO2 emission of 56% compared to the reference design. This is a saving of 200,000m3 of concrete.

XblocPlus

Between 2015 and 2018 DMC developed XblocPlus. This concrete block is a further development of Xbloc which has been applied worldwide since 2004 and is used to protect breakwaters and shore protections against waves.

With sea level rise and increasing storm intensity, wave loads on coastal structures are increasing and Xbloc and XblocPlus provide protection.

XblocPlus has significant advantages compared to other armouring solutions:

  • Resilience to the uncertain climate change by an increased intrinsic safety factor in the design.
  • A reduced concrete consumption
  • A reduced CO2 emission
  • Reduced construction time
  • Increased safety during construction
  • Easily adjustable to stimulate marine life in and around breakwaters and shore protections
  • The aesthetic appearance makes it very suitable for shore protections in urban environments and for marinas.

What is the difference between XblocPlus and Levvel-bloc?

Therefore there is no difference between the two blocks. Levvel-bloc is the name under which the block is used in the Afsluitdijk Project.
