Ribraft Pod Slab

What is Ribraft Pod Slab?

The Ribraft Pod Slab System is a better way of building concrete slabs for new homes, extensions or commercial industrial buildings. A ribraft slab foundation is an above-ground foundation used to provide load-bearing capacity in expansive, rocky or hydro collapsible soils. The foundation consists of a perimeter flooring and a series of narrow internal beams or strip footings with one-meter centres running each way. Edge formwork makes the sides of the slab and pods create voids between the strip footings.

DESIGN OF A RIBRAFT POD SLAB

The ribraft pod slab consists of 4 main steps in the construction process:

Ensuring the building site is level – If the building site is not level, it is required to cut and fill the site until the surface has become completely flat and levelled surface has been achieved.

rib raft pod layout – Once the site has been levelled and first plumbing alongside white ant treatment has been conducted the pods are ready for layout. The area is then set up with outside edge boards and covered in plastic sheeting. Next, the rib raft pods are laid out with spacers in a grid pattern within the formwork.

Reinforcement bars – After this, the reinforcement bars are
dropped on top of the spacers between the rib raft pods. The top mesh is then laid.

Pouring concrete – Finally, the concrete is carefully poured, ensuring the intersecting are completely filled, and the waffle pods and mesh are covered
