Half slabs are prestressed concrete elements that have a constant cross section. They are manufactured using high tensile strength prestressed strands or single wire which are embedded within the element.
The production of these elements is achieved using our Slipformer or Wet Casting machines that cast an element continuously on a long production bed without the need of any formworks.
Half slabs are used as covering elements in residential, social and commercial construction. Half slabs are used in construction projects that have high loading and/or large spans.
A floor is usually made of half slabs with hollow blocks (concrete or clay) or polystyrene in-fills. The concrete and clay in-fill blocks can be laid in two layers. The in-fills keep the weight of the floor to a minimum and are then covered with in-situ concrete to form the ribs and the floor slab.
As well as the prestressed wire reinforcement the half slabs have steel mesh embedded in the lower part to further increase the element strength.
