Flooring and ceiling slabs



Hollowcore Units derive their name from the circular voids or cores which run throughout the slab. The units have a smooth finish and maximum capacity of 2.3 kn/sqm over a 16m span. They are available in standard 1200mm widths and in depths of 150, 200, 250, 300 and 400 mm. They can be used effectively in all types of building providing a fast and cost effective structure.
Typical Applications include:
Flooring or roofing for single and multi-storey developments. The long spans of up to 16.5m are ideal for most residential or commercial applications such as apartments, offices, factories etc.
Wall Panels – Hollowcore can be installed either horizontally or vertically to provide an effective wall cladding system, often used with steel structures.

Hollowcore spans up to 16.5 m. which minimises column requirements
Factory production decreases dependency on weather conditions and increases programme planning reliability.
Eliminates the requirement for costly excavation for ground floors, removes the need for provision/ compaction of infill material and provides an immediate dry working platform.

Wideslab is a solid precast slab, which is pre-stressed to provide excellent span/ ratio depth. The standard slab width is 2400mm and available in depths of 80, 100, 125, 150 and 175 mm depths (our standard sizes are 100 and 150mm). Wideslab is often used with a structural screed, to aid stability of the structure and increase its load capacity. Maximum spans are about 8.5m, depending on loads.
Wideslab can be used as both flooring and wall panels.
Structural Wideslab is often used for offices and apartments where floor construction depths need to be minimised.
They can accommodate large loading requirements for developments such as car parks or plant rooms.

Superior soffit finish ideal as finished surface
Modular width of 2400mm reduces number of joints and erection time
Shallow floor construction reduces floor to floor height.
Composite action enhances structural integrity and robustness
A lattice girder can be used, which increases the spanning capabilities of the unit and robustness of the flooring system.
