Waffle Pod Systems
THE NEW, ECONOMICAL WAFFLE POD and RIBBED RAFT SLAB FLOOR SYSTEM.
In the past, domestic footings were based on a concrete beam method that usually required extensive, backbreaking digging. Apart from the manual labour involved, there was always the added difficulty of trying to accurately control the amount of concrete used. During wet weather trenches and steel would need to be cleaned again, hence adding further cost and lost production. In 1982 as an alternative, the Waffle Raft System was developed. Tests took place and the results was sensational. Polystyrene voids turned out to be the best, most environmentally friendly material to use, since it made the void former easier to handle and store, it was less expensive than the alternatives, and consistently performed well. The other advantage was that unused void pieces are completely recyclable.
Developed by SARTAS (NSW), manufactured for SARTAS (NSW), under very strict high standards of quality control and being accredited with ISO 9002 accreditation, the polystyrene voids are built from heavy duty moulded polystyrene which are specially designed to resist heavy rain, and can easily carry the weight of the workmen. In fact, the system proved to be so revolutionary that the Standards Association of Australia Codes were eventually changed in 1988 to incorporate it. They are as follows: Concrete and Design of Residential Slabs and Footing Codes AS 2870.1-1996, AS 2870.2-1988, and Concrete Structures Code AS 3600-1988.
The Waffle Pod and Ribbed Raft System has now been developed and recommended by many of the country's leading consultant structural engineers to provide a more economical method of construction. The system is now used exclusively by most major home builders, government departments and major building contractors.
The Waffle Pod and Ribbed Raft Slab Floor System is an innovative method of constructing slabs that uses moulded void formers which are arranged on a levelled building area in a grid pattern. This system uses less concrete than the conventional method of edge beam and internal beam, trenching, so the need for labour intensive digging is eliminated. Since the void formers are waterproof, this system can even be used during wet weather conditions.
WHAT IS THE DIFFERENCE BETWEEN A WAFFLE POD AND RIBBED RAFT WAFFLE POD SYSTEM?
The Ribbed Raft Waffle Pod System has been designed for single story brick veneer dwellings placed on a S or M classification sites.

By spacing the ribs further apart in the Ribbed Raft Waffle Pod System (see left hand side of diagram), less concrete and steel is used. The builder must be guided by the engineer to what system best suits the situation.
The polystyrene voids function as insulation pockets, significantly reducing heat loss through the floor.
Difficult or cut and fill soil area are no longer a problem. This system features greater strength and stiffness than conventional footing techniques, with higher resistance to cracking.
