Should I use a Waffle Pod Slab or a Conventional Slab?

All new building projects must go through an organisation and planning phase.

This is typically the first initial stage of any new construction project and is commonly used to determine what exact materials will be used during the building process.

The first building material utilised for any construction project is typically in the foundations.

Commonly called slabs or foundations; there are two main types of slabs, the conventional slab and a waffle pod slab.

Both slab types offer distinct benefits related to building stability, ease of construction, suitability to site conditions etc.

Factors to be considered when deciding which slab design is suitable for your next project.

Should I use a Waffle Pod slab or a conventional slab? 

Waffle pod slabs are relatively new, however, they are used in both commercial and residential buildings.

The main benefit of using waffle pod slabs is that they are considerably more economical than traditional raft slabs.

Waffle pod slabs use foam void formers to create the volume required for the ground slab.

Conventional raft slabs, on the other hand, create the slab entirely from concrete and reinforced steel.

One of the primary differences between traditional raft slabs and waffle pod slabs is conventional slabs require trenches to be dug before installation.

Both provide sufficient durability and reliability when used to suit the site conditions.

Choosing the right slabs for your next construction project 

For starters, if you live in an environment with heavy rainfall or abrasive water-related weather conditions year-round, conventional raft slabs may be a better option.

While waffle pod slabs are more economical, however, they may not be suitable for sloping ground or soft ground conditions.

As waffle pod slabs are faster to install than conventional raft slabs they save time which reduces overall construction costs.

People also ask 

Q: What are waffle pods used for?

A: Waffle pods are commonly used in the construction of new residential homes, commercial buildings, and as extensions to existing slab infrastructures.

Q: How long does a waffle pod slab take to dry?

A: On average, it takes about seven days for a waffle pod slab to dry. Refer to the relevant Australian Standard for the timeframe required before further construction can commence.


By now, you have a better understanding of the core differences between waffle pod slabs and conventional raft slabs.

So, if you wish to lower construction costs, and if site conditions are suitable, consider installing a waffle pod slab for your next project.
