Hollow core slab

It is a type of precast slab through which cores are run. Not only do these cores decline slab self-weight and increase structural efficiency but also act as service ducts. It is suitable for cases where fast constructions are desired.

There is no restriction on the span of the hollow core slab units, and their standard width is 120mm and depth ranges from 110mm to 400mm.

The slab units are commonly installed between beams using cranes and the gaps between units are filled with screeds. It has been observed that, hollow core slab can support 2.5 kN/m over a 16m span. It is suitable for offices, retail or car park developments.
