Hollow Core

Hollow core slabs are precast, pre-stressed concrete elements. Primarily used as floor or roof deck systems, hollow core slabs also have applications as wall panels, spandrel members and bridge deck units.


  • Long spans, no propping
  • Light weight
  • Flexible in Design
  • Fast construction

Continuous voids in the slabs provide reduced weight, and therefore, cost, and also the possibility for concealed electrical and mechanical runs. Studies have shown that hollow core slab elements weigh up to 40%-50% less than traditional reinforced concrete slabs of the same dimensions. The slabs are reinforced with 9.53 mm and 12.7 mm steel strands running longitudinally.

Emarat Europe’s hollow core plant has eight beds and seven hollow core modules and hence can offer a range of floor slab depths, depending on the project requirements.

Emarat Europe’s hollow core slabs have between six or eleven longitudinal cores running through them. The slabs are pre-stressed with thicknesses of 150 mm, 200 mm, 220 mm, 265 mm, 320 mm, 350 mm and 400 mm up to a span 22 m.
