An engineered concrete raft slab and flooring system that offers real benefits over a conventional concrete slab foundation.

SuperSlab is an above-ground engineered concrete slab foundation system, commonly known as a raft foundation, pod floor, waffle slab or floating foundation, that delivers real benefits over conventional concrete floors and foundations. It is an advanced concrete slab foundation in New Zealand designed to meet the unique needs of residential, commercial and industrial projects.

A grillage of beams within the concrete slab foundation 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.

 Benefits:

SuperSlab has the following benefits over conventional floors and foundations, making it a preferred choice for a wide range of construction projects involving a concrete slab foundation in New Zealand:

• Faster installation — The modular design of SuperSlab allows for quicker assembly, reducing construction time and labour costs.
• Minimal excavation — Requires less site preparation, saving on earthworks and enabling easier installation on various ground conditions.
• Low soil-bearing capabilities (perfect for soft ground) — Ideal for soft or weak ground conditions, SuperSlab distributes weight evenly across its raft foundation, ensuring stability.
• Multiple pod void formers are available — Offers flexibility in design with a choice between traditional polystyrene pods and the sustainable QPOD system, catering to project-specific needs.

• Easy service installation — Designed to accommodate plumbing, electrical and other utilities efficiently, simplifying integration during construction.

Sustainable, Compliant and Versatile Flooring Solution

QPOD

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

QPOD reduces environmental impact while maintaining the structural integrity required for raft foundations. These pods are easy to install and match the dimensions of standard polystyrene void formers, making them a seamless substitute.

QPOD ensures minimal waste during installation and contributes to thermally insulated foundations, enhancing the energy efficiency of buildings. Its compatibility with various soil types make it a dependable choice for foundations in residential, commercial and industrial projects.

By integrating QPOD into your SuperSlab system, you support sustainable building practices without compromising performance or compliance. Our slab foundations with QPOD offer a sustainable solution that supports New Zealand’s commitment to eco-friendly construction, all while providing the exceptional strength and reliability you’ve come to expect from Allied Concrete.
