What is hollow core slab?

A hollow core slab is a precast concrete flooring system characterized by its lightweight, hollow tubular sections that run parallel to the length of the slab. These voids reduce the overall weight of the slab while maintaining structural integrity, making it efficient for spanning longer distances. Hollow core slabs are commonly used in commercial and residential buildings for floors and roofs due to their quick installation and Excellent load-bearing capabilities. Additionally, they offer good thermal and acoustic insulation properties.
