Polystyrene rafts and waffle pods have revolutionised the concreting industry
over the last decade. A waffle pod system can save considerable money – site
preparation is much simpler and there are significant savings in the amount
of concrete used.
The polystyrene raft is also a great insulator, reducing heat transfer through
the floor.

The on-ground system (rather than in-ground)
slab, eliminating the need for labour intensive trenching - formerly essential
to create underfloor concrete beams in conventional slab construction methods.
Construction takes place on cleared level surfaces, allowing work to continue
uninterrupted in inclement weather conditions.

| The Wafflepod system uses polystyrene void formers arranged on the levelled
building area in a grid (waffle) pattern with reinforcing between and above
the voidformers. Concrete fills the spaces between and across the Ribbed
Raft to form a slab over the entire area. The spaces between the void formers
effectively become concrete beams on ribs resulting in a slab which is a
structural element of immense strength. |

What are the Wafflepods made of?
Each pod is manufactured from Expanded Polystyrene. In Australia CFCs have
never been used to make expanded polystyrene foam (EPS) which is turned into
wall insulation panels, agricultural produce boxes and moulded protective packaging.
This type of polystyrene is expanded using hydrocarbons, mainly pentane.
All Waffle Pods are 1090x1090mm designed to be used in conjunction with a
110mm beam system - creating a 1200x1200mm grid effect.
The Pods are supplied in thicknesses of 150 / 225 / 300mm thicknesses and all
accessories can be supplied.

Details for pod calculations (approximate) are as follows:
Method
1 |
Divide m² of slab by 1.51 this will equal
number of pods |
Method
2 |
Multiply the perimeter beam length by 0.135 this will equal
m² of edge beam, deduct m² of edge beam from total m² of
slab, divide the resultant by 1.44 to get the number of pods
required |
Spacers |
Multiply the total number of pods by 3 to calculate the
total number of 110mm spacers (including 1-way & internal 4-way spacers).
Alternately, multiply the total number of pods by 1.2 to calculate the number
of 110mm – one way spacers only. Divide the total length of the perimeter
beam by 1.2 to calculate the total of 300mm or 270mm edge spacers required. |
Chairs |
Multiply the total number of pods by 3 to calculate the
total number of mesh chairs (25/40) required. |
