Hollow Core Slab

A hollow core slab, also known as a voided slab, hollow core plank or simply a concrete plank is a precast slab of prestressed concrete typically used in the construction of floors in multi-story apartment buildings. The slab has been especially popular in countries where the emphasis of home construction has been on precast concrete, including Northern Europe and former socialist countries of Eastern Europe. Precast concrete popularity is linked with low-seismic zones and more economical constructions because of fast building assembly, lower self weight (less material), etc.

The hollowcore slab utilizes the compressive strength of concrete with the high tensile strength of steel strand. Slabs are produced at the factory under rigid quality control conditions, then shipped to the job site for incorporation into the structure, for a proven efficient and fast method of construction.

As industry leaders, Hollow Core has served an array of prestigious clients and has assisted them in achieving quality outcomes which are both economic and reliable. The aim of our company is to provide cost effective structural designs and products which are of the highest standard.

a) Why use Precast Concrete Hollowcore Slab ?

  • Hotels
  • Apartments
  • Office Blocks
  • Car parks
  • Industrial Buildings

b) Benefits of using Hollowcore Floor Slabs

  • Quick installation ensures a reduction in building programme time and site costs.
  • Eliminates the need for costly and time-consuming on-site concrete pours.
  • Eliminates on site formwork and steel fixing.
  • Units can be grouted immediately after installation.
  • Immediately stable floor platform suitable for working off.
  • High load capacity and long spans.
  • Provides high levels of inherent fire resistance.
  • The hollow cores provide an excellent sound resistance.
