Rib and Block Decks
  • Less weight
  • Higher flexibility
  • More carrying capacity
  • Advantageous economy
  • Better environment protection
  • Reduction of material consumption and transportation costs
  • Improved quality through industrialization of reinforcing work.


In order to save weight in concrete building, one-way hollow decks have been used in some countries for the last 40 years. Unfortunately, these decks have the disadvantage of transmitting forces in one direction only, so that they need support by beam constructions or carrying walls at both ends, which results in rigid, inflexible and unalterable buildings.The Precast Rib and Block Decking System solves this problem simply and effectively and simultaneously offers completely new possibilities.


Such As:

  • Larger deck areas with less supporting points (e.g.:No carrying walls, room distribution and size may be changed repeatedly even in the finished building, and in multi-storey car-parks as well as in halls the much larger distance between supports is extremely advantageous).
  • Lower construction depth (in high-rise buildings this gives more floors within the same building height)
  • No beams or ribs under the ceiling; pillars have no capital
  • Simplification of subsequent work, areas not needed are simply cut out (e.g. for a spiral staircase)
  • Higher quality through automated production of prefabricated units
  • The lower weight of construction parts also allows for less heavy equipment (cranes etc.)

Environmental Improvement
Aspects of the Rib and Block Decking System are substantial, since:

  • Much less concrete is needed
  • Transportation of materials is reduced proportionally (fewer truckloads / helicopter flights)
  • All components are easily recycled when the building has to be removed.

Economic Savings:

  • Manual mounting of reinforcement meshes on the building site is avoided (erection time is reduced)
  • Savings in materials (slabs, pillars, fundaments) are important (up to 50%)
  • Transportation costs are heavily reduced
  • Subsequent work (installations) are simplified
  • Buildings are more flexible, changes are much less costly, life span of buildings is longer.
    All saving effects combined may offer a savings potential of 5 to 15% on the carcase.
