Prestressed Hollowcore Slabs
Discover how hollowcore slabs are manufactured, their advantages as a sustainable building element, and some of the projects our members have completed around the world.
Why Hollowcore
Precast prestressed hollowcore floors offer 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 hybrid 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.
Member Projects
