We can explain the large use in the contemporary building stock of the prefabricated hollow core floor slab with all the various advantages it can offer: it has a high adaptability to the functional exigencies, it is guaranteed to be totally self-supporting in any phase of handling, transport, erection and works in place that eliminates any support work, finally it has excellent soundproofing properties.
Furthermore the hollow core floor slab is a very light element that can be erected very rapidly. Mabo realizes its hollow core floor panels following two technologies: extrusion, based on the establishment of a contrast force of the moulding machine against the element, and vibrocompaction realized through a machine that produces the panel through a steady juxtaposition of little blocks.

For use in self-supporting floors, coverings and walls for civil, commercial and industrial buildings, carparks (including underground) and the service sector.

The Gruppo Centro Nord has introduced the new size of the pre compressed reinforced concrete alveolar attic with FORAP. They are structural elements with thickness from 60 to 100 cm.

Almost all our standard cross sections can be used for BRESPA® Ventilation Floors. The principle is simple yet brilliant: the voids are coated and used as aeration channels. Exhaust and fresh air valves are placed directly into the soffit of the floors. Additional aeration channels for lateral distribution are therefore not required below the ceilings. Room and building heights can be reduced.
It is important to decide early for the application of BRESPA® Ventilation Floors, to use these ceilings soon, because this will influence positively a multitude of decisions for other areas of your building.

The RECTOR manufacturing process uses high performance concrete put in place by an extruding machine. The hollow core slabs are manufactured on 100 to 130 m long benches
Cylinders are used to apply tension to the strands.
A programmed heat treatment allows for faster hardening of the concrete.
The RECTOR hollow core slabs are used for the installation of long span horizontal surfaces: industrial, service, school and parking buildings and housing.
They constitute finished heavy-duty elements or are associated with a table acting compositely. In the latter case, the upper surface of the slab is treated so as to obtain a good roughness.

Prestressed hollow-core floors belong to the most modern floor systems because of the efficient design and production methods, the choice of unit depth and capacity, the surface finish and the structural efficiency.
The presence of longitudinal voids in the cross-section leads to a 50% saving in concrete compared with a plain slab, and at the same time reduces the amount of prestressing steel by 30% because of its lower weight.
Consolis is Europe´s leading manufacturer of precast prestressed floors with an annual production of over 7 million m². With industrial innovations such as pipe floors and integrated hollow-core slabs, Consolis makes it easy for the builder, designer and buyer to configure the accommodation freely.

These panels prefabricated out of large-sized prestressed concrete make it possible, by their juxtaposition, to carry out floors of great range and compactness. To associate or not with a flagstone of in situ compression.
Scope of application:
The Alveolate Flagstones are implemented in all the types of works. They find a use privileged in the construction industries where the range of the floors is large in order to release a suitable big space.
The Alveolate Flagstones find are used in the realization of the floors of the buildings of writing desks, industrialists and of carparks.
