Precast Voided Floor Slab

In Category:Floors & Stairs

The Voided Floor Slab is a reinforced precast concrete slab which incorporates the cobiax void former system.

All reinforcement used in manufacturing is multicycled steel. Once placed by the erection team the filigree plates are covered with in-situ concrete. This void forming system reduces the volume of concrete required in the floor without compromising the design of the slab. The reduced concrete volume then means the self-weight of the slab system is lowered with consequential savings made to the foundations or any secondary supports.

The draughting software is able to communicate directly with the factory to eliminate the human interface and help produce zero defects. The slabs can be detailed to infinitely variable shapes to suit the clients design layout.

Our precast flooring system has a soffit which is ready to accept direct decoration.  When the Omnia Slabs are used in conjunction with our twin wall product and the screed is poured on top of the floor the concrete screed flows down into the walls making a strong robust connection between the walls and the floor. It also offers air tightness and acoustic levels which cannot be matched by any other precast system.

We hold ISO9001:2008 certification for the design and manufacturing of the slabs
