SuperSlab: Concrete Raft Foundation

READY Super Slab QPOD - Raft Foundation - Allied Concrete

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

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 conventional concrete floors 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.
