  • the corresponding Hollow bodies or partial hollow bodies can also be used to Absorb liquid or inert material and, for example, fire resistance to provide, which makes the use possible even in extreme situations.
  • the individual component is made from individual nested individual layers, whereby this gives the possibility of specifying a construction that once due to the extensive training and on the other hand due to the corresponding Shaping to create wall thicknesses of practically any thickness or with corresponding ones mutually touching hollow bodies, the ones described above Bring advantages.
  • the low weight of such is particularly impressive Components and the high stability that u. a. also through the flat connection achieved and support and formation of stable walls is achieved.
