Definition of terms
To describe the Cobiax products unambiguously and clearly, we have agreed on a uniform set of terms. We would like to clarify these terms here in general.
When people talk about Cobiax in a practical sense, we speak of the Cobiax system or Cobiax technology. The Cobiax system or is used to build special slabs of reinforced concrete.
Slabs in which the Cobiax system is installed are called Cobiax voided flat slabs or simply Cobiax slabs. They consist of a void former zone on the one hand and a solid zone on the other. The installation elements are used in the void former zone.
