The cobiax® technology allows an integrated concrete slab construction for long spans without beams which is a requisite to realise an increased sustainability of the building value and at the same time save resources.

Conventional Flat plate slab

Cobiax® removes the non-working dead load in a concrete slab while maintaining biaxial strength. This is achieved by placing hollow plastic voids within the concrete slab.

cobiax®Integrated cost optimisationThe cobiax® technology optimises the lifecycle cost and can also decrease the over all building cost. The below real-case example illustrates this fact (Eco-Line, insitu).

Cobiax® is available as cage module CBCM and semi-precast CBSP and is suitable for in-situ applications as well as for the combination with precast slabs. The cobiax® technology can be used with other building techniques such as post tensioning and composite structures. Cobiax® can be adapted to any layout. The arrangement of the cobiax® void formers and the size and shape of the panel are determined by the project requirements.

Cage Modulecobiax® CBCM

Semi-Precast cobiax® CBSP

The available cobiax® void formers’ dimensions range between 100 mm and 450 mm. The cage modules are available in two standard executions – Slim-Line and Eco-Line. They are differentiated as follows:

We are keen to provide preliminary advice for your projects by optimising the ratioslab thickness : span : loads.

A modular concept

Slim-LineFor thin slabs in the range between 200 and up to 350 mmEco-LineFor slab thicknesses in the range between 350 mm and 600(+) mm
