Prestressed Hollowcore Slabs

Discover how hollow core slabs are manufactured, and their advantages as a building product.

Why Hollowcore

Precast flooring, and prestressed hollowcore in particular, offers many advantages over alternative methods such as in-situ concrete, steel and timber. A lightweight solution which allows long spans between supports, hollowcore can be utilised in full precast or mixed construction, and in a huge range of applications.

Production

Hollowcore is manufactured on long line steel casting beds using extrusion, slipforming or flow forming machines. The process begins with design of the slabs according to project requirements, through bed planning, manufacture, curing and removal to the stock yard.
