Technology – Implementation

Simple and safe in use

The Cobiax voided flat slab is easily produced: Cobiax void former modules are mounted in the relevant spaces between the upper and lower reinforcement where they displace the concrete and serve as support for the upper reinforcement.

Three easy steps to implementation

  • easy installation of modules by hand
  • precise assembly using an installation aid
  • straightforward concreting in two stages for buoyancy free installation

Customized installation:
Cobiax voided slab modules always fit perfectly.

  • Precast element version
  • Combination with post-tensioning
  • Assembly into pre-assembled parts
  • Combination with concrete core activation
