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.

3. Installation element
Installation elements refers to the objects that are actually to be built into the slab. They consist of different components depending on the product line.
The installation element of the Cobiax EL is called void former module. Its components are:
- 5 up to 8 void formers
- 1 fixing element made of steel (cage-shaped)
This is the installation element of the Cobiax EL with 7 void formers.
The components of the installation elements of all product lines are called void formers.
The void former component of Cobiax EL consists of a single sphere.
