General information

Rib & block slabs remains the most cost effective solution for suspended flooring.
Through innovative design we can offer our clients the versatility for irregular shapes, excellent structural integrity and improved sound and heat insulation. These benefits together with ease and speed of erection offer substantial savings over in-situ slabs.
The rib and block system consists of pre-stressed ribs, hollow core blocks, Y-10 rebar and Ref 100 Mesh. This system can be used for basement slabs, first floor slabs and roof slabs.

 

Benefits of SPANCON Rib & Block slabs

  • The structural integrity of the rib and block slabs is the primary benefactor for this system.
  • Versatility for different architectural designs including cantilevers makes the rib and block slabs the preferred choice!
  • Improved sound and heat insulation further enhance this system.
  • The electrical slab boxes, which are the same size as the concrete slab blocks, allow for down-lighters anywhere in the slab and the electrical conduits to be positioned correctly. Electrical and plumbing services can easily be accommodated
  • Plastered smooth ceilings with no grooves give a quality finish to your slab.
  • Easy installation guaranteed! No cranes or formwork needed.
  • Reduced cost for labour, installation and very quick to install.
  • Leveling of slab is done while packing the slab, as the weight of the concrete pre-stressed ribs and blocks press down on the props.
  • A rib and block slab system is 30% lighter than a solid cast system on the supporting walls and foundation
  • Reduction in the use of form work and scaffolding
  • The rib and block slab is the most cost effective slab option as it uses less Ready-mix and steel which is the most expensive part of any concrete slab
  • All material are factory controlled quality products that adheres to all prescribed standards
 
Our clients include home owners, builders, developers, architects and engineers in the domestic-, commercial- and industrial development market. Preliminary quotes are done based on either verbal specification from clients or from the plans submitted. Final measurements need to be taken on site, to finalize the structural engineer’s slab design and to ensure that the correct lengths and quantities are supplied for the slab.
 
Pre-stressed Rib and Block precast suspended slabs have a proven track record of over 40 years. This highly successful, innovative design offers versatility for apertures, irregular shapes and down lighters. Furthermore, precast concrete hollow block slabs exhibit excellent structural integrity, improved sound and heat insulation, and allows for a high quality plastered soffit finish.
