SuperSlab — Engineered Raft Foundation and Flooring System

SuperSlab is an above ground engineered raft foundation system, commonly known as a raft foundation, pod floor, waffle slab or floating foundation, that delivers real benefits over a conventional concrete floor and foundations.

A grillage of beams within the concrete slab provides a stiffer and stronger final product than a conventional 100mm concrete slab on grade, and because of its inherent strength, a deepened perimeter footing can usually be omitted.

Key Features
  • Speed of installation offers labour savings and reduced build time.
  • Minimal excavation  
  • Suitable for poor sites with low soil-bearing capabilities  
  • Improved thermal performance (R-value)  
  • Easy installation of services 
  • CodeMark certified and BRANZ appraised
Scope of Use

SuperSlab can be used on all ground conditions regardless of your land classification, including:

  • Residential foundation and floor slabs 
  • Shed floors
  • Small commercial buildings
  • Warehouses
Statement of Building Code Compliance
  • SuperSlab is BRANZ appraised and CodeMark certified.
Other Performance Attributes

Super Slab includes QPOD as a sustainable alternative to traditional polystyrene pod void formers within the raft foundation system. Polystyrene pods can be directly substituted for QPOD, with four pods replicating the standard 1100mm x 1100mm sqm and 220mm deep polystyrene pods.


Key benefits include:

  • Made from recycled material and 100% recyclable with zero landfill waste
  • Reduced site waste 
  • Efficient transportation and storage (pods for a 180sqm home can be transported on the back of a ute or single-axis trailer)
  • Ease of installation in windy conditions
  • A CodeMark-certified plastic pod raft flooring system
  • Integrated 40mm spacer eliminates the need for mesh chairs
  • Stability - pods interlock to stay put during concrete pour and windy conditions
