Are Waffle Pod Slabs Cheaper Than Conventional Slabs?

Any new construction requires a solid base like a slab or foundation. Choosing the right foundation for your building is probably the most critical factor in the entire building process.

So, you need to select the correct type of slab to form your foundation to ensure it will last.

There are two main types of slabs available for building purposes, waffle pod slabs and conventional slabs.

Both of these slab types provide unique benefits and advantages, depending on what you’re trying to achieve.

Factors like durability, build efficiency, and safety are all factors you need to consider before deciding on which slabs you’re going to use.

Another critical factor to consider is cost.

To help you make the right decision, we’re going to provide you with a detailed explanation of each slab type below.

Are waffle pod slabs cheaper than conventional slabs?

For starters, waffle pods cost significantly less than traditional raft slabs.

This is one of the reasons why many builders and contractors are opting for waffle pods instead of regular raft slabs in their new projects.

Conventional raft slabs require trenches before installation; waffle pods do not.

Traditional concrete raft slabs also require more time to settle and install overall than waffle pod slabs.

Waffle pod slabs are innovative because they use polystyrene void formers rated for efficient thermal insulation.

Waffle pod slabs are also very lightweight and much easier to handle than traditional slabs, reducing the overall amount of labour involved.

These factors generally mean that a waffle pod slab will be significantly cheaper than a regular concrete raft slab.

Some soil classifications will not allow a waffle pod slab to be placed and this is usually when a conventional slab will be chosen over a waffle pod slab.

A waffle pod slab can stop being cost effective if the project is in a remote area, where the transport costs for the waffle pod void formers outweigh the cost savings in a typical waffle vs conventional slab comparison.

Getting the most value out of your next building project 

When you factor in their reduced cost, you can see why a lot of builders are using waffle pod slabs where possible.

If you’re working on a new building or construction project in a wet environment, you should go with a conventional slab as it will last much longer.

People Also Ask 

Q: What is the difference between a raft slab and waffle slab?

A: The primary difference between the two is raft slabs cast against the ground. Waffle slabs, on the other hand, cast upon polystyrene void formers and strips of concrete.

Q: Why do they put foam under concrete?

A: Contractors and commercial builders use foam under concrete to stop upward vapour diffusion. It also helps minimize moisture retention in the concrete.


Now that you know waffle pod slabs usually cost less than conventional slabs, it’s time to make a decision about which one is right for you.

Use the information and tips we’ve given you in this article so you can find the perfect slab for your next construction project.
