Types of precast flooring

General information on the various flooring systems is available in a series of datasheets. Each type is briefly described below.

• Beam and Block Floor Systems combine precast prestressed concrete beams and infill blocks to produce high quality economic ground and upper floors in residential and other building types. Find out more.
• A hollowcore floor slab is a prestressed precast concrete element incorporating continuous voids to reduce self-weight whilst providing an efficient structural section manufactured by slipform, extrusion or wetcast. Find out more.
• A composite hollowcore floor combines precast hollowcore units with a structural concrete topping resulting in enhanced structural performance and lateral load distribution. Find out more.
• Composite floors using lattice girder normally consist of a temporarily propped precast plank, which also acts as fully participating permanent formwork in conjunction with the in-situ structural topping. Find out more.
• Solid prestressed composite floors consist of a solid prestressed slab acting as fully participating formwork, which may be propped or unpropped depending on design requirements and which acts compositely with an in-situ topping to form an efficient structural section. Units are manufactured on beds varying in length between 50m and 200m using slipform or extrusion techniques. Find out more.
• Precast concrete staircases and balconies complement precast and prestressed concrete flooring systems. They may be standard products or purpose made to suit those areas of the building where solid reinforced concrete construction is needed. Find out more.
