StyroPod by Foamex is an Australian made, lightweight EPS waffle pod void former ideal for use in concrete slabs during the building & construction process. 


Designed specifically for use in residential building applications, StyroPod (formerly known as Diamond Pod) waffle pods provide under slab insulation and support, working in unison with natural soil movements, and lowering the amount of concrete required for a build. With the StyroPod system construction is quicker and more cost effective compared to traditional concrete pours. A higher level of insulation is achieved through the natural air pockets in the expanded polystyrene and the moulded cells within the waffle pod design. StyroPod waffle pods can be used with any bracket and steel reinforcing mesh systems.

Expanded polystyrene waffle pods have contributed to a revolution in slab construction methods, enabling stronger, better engineered slabs to be constructed faster and more cost effectively than traditional methods. Manufactured from high quality, Australian, expanded polystyrene, StyroPod waffle pods are unaffected by water, so therefore safer to install as there are no trenches to cave in during construction. The inclusion of StyroPod waffle pods in a slab adds an insulation benefit of up to R1.0 (W/mk thermal resistance) as standard, which helps to reduce energy consumption in residential buildings. When used in conjunction with exterior slab edge insulation systems, the thermal value of the slab system can met and often exceed the most stringent energy efficient standards.

Why StyroPod?

  • Lightweight, durable and easy to handle
  • Weather resistant with low water absorption
  • 100% recyclable & sustainable
  • Engineered to be stronger than standard waffle pods
  • Complies with Australian Building Codes & Standards


  • lightweight reverseUnderslab insulation

A unique, patented design

The unique size and diamond cut shape of Foamex StyroPod offers optimal support for foot traffic during construction. The foam deck of the StyroPod product is thicker than other standard waffle pods, and additional material is compacted into the base during the moulding process, meaning a concreter's boot is supported by the deck which spreads the load across a minimum of four support pillars. This is incredibly important to maintain Occupational Health & Safety on building sites.

StyroPod, manufactured from Australian Styroboard EPS expanded polsytyrene, has been specifically engineered and designed using a patented, customised moulding machine to create the diamond shape. The geometric shape of this diamond offers a more uniform and high strength waffle pod. Furthermore, the state-of-the-art technology and innovative design of the moulding machine uses no water and produces less waste, making StyroPod environmentally friendly to produce. 

Sustainable Business Practices

Foamex is committed to ensuring that StyroPods are delivered responsibly to construction sites and that offcuts are returned for recycling. Foamex adheres to the Pod Code of Practice as laid out by the peak industry body Expanded Polystyrene Australia (EPSA). Our pods are delivered to construction sites tightly wrapped together with plastic shrink wrap, and then further secured on-site with netting, which is attached to pegs in the ground to minimise the risk of blow-away and damage. Every order of StyroPod is delivered with bags to store off-cuts and leftover polystyrene. We then pick up these leftovers from site and repurpose them into new EPS products.

Our commitment to sustainability extends to how we operate our facilities. In Victoria and South Australia we are fully powered by renewable energy sources from solar and wind farms.


StyroPod is available in a range of standard sizes


StyroPod waffle pods come in 4 convenient sizes to suit all types of construction and soil types, as outlined below. Alternatively, we can custom make a StyroPod to suit your specific requirements.

150mm StyroPod

Can be used in shower or garage set-downs, ideal for situations that require step down or height variations across the slab.

225mm StyroPod

Best for moderately reactive clay or silt sites which can experience moderate movement from moisture change.

300mm StyroPod

Can be used in highly reactive clay sites, which can experience high ground movement from moisture change.

375mm StyroPod

Recommended for use in extremely reactive sites that experience substantial ground movement from moisture change.



StyroPod 4 Way Spacer

Uniquely designed for the easy placement and positioning of the reinforced bars through the internal sections of a slab, the StyroPod 4 Way Spacer assists with a uniform concrete flow to ensure a cost efficient construction to Australian building standards. 

The StyroPod 4 Way Spacer is available in two sizes: 100mm, 110mm.

StyroPod 4 Way Interlock

The StyroPod 4 Way Interlock is a highly effective, time saving design that ensures the StyroPod waffle pods are secure and held in place, providing increased stabilisation during concrete pours and guaranteeing a uniform concrete flow. Simply slot into the lugs located at each corner to hold the pods tightly in place, this accessory also allows for double stacking of pods.

The StyroPod 4 Way Interlock is available in two sizes: 100mm, 110mm


StyroPod 2 Way Spacer

Cleverly designed to fit 100mm or 110mm internal spacings, the StyroPod 2 Way Spacer can be used in between pods as an internal bar support, wherever steel supports are required, or in trenches throughout the slab.

StyroPod Rails

A unique, simple design with stabilising spikes that ensures waffle pods are secure, even when exposed to high winds or inclement weather, StyroPod Rails offer superior concrete flow and reinforcing mesh support. The wide base of the rails spreads the weight of the reinforcing mesh evenly over the waffle pod. StyroPod Rails increasing end user productivity, reduces labour time, and also helps to improve slab safety and quality.

StyroPod Rails are available in the convenient size of 600mm L x 75mm W x 40mm H

StyroPod Slab Edge Spacer

StyroPod Slab Edge Spacer

The StyroPod Slab Edge Spacer has been specifically designed for the easy placement and positioning of the edge beam bars along the outer edge of a slab. Available size: 110mm.

EPS Recycling Bags

We strictly adhere to the Industry Code of Practice which outlines the responsible use of EPS pods on building sites. Our EPS recycling bags enables scrap off cuts to be collected and recycled by our state-of-the-art recycling plant, and put back into sustainable building products.
