Great information from Matthew Cornell, full marks
I have inspected close to 10000 homes either during construction or finished at various ages for pre purchase or defect inspections. My firm belief is that regardless of theory, in practice the waffle pod slabs are a lot closer to risk edge cliff than conventional raft slabs and I would avoid them whenever possible. Whatever cost and operational advantage waffle slabs are to the builder it is not passed on to the owner and instead owner takes up the much higher risk of failure for no benefit at all.
I have just come off pre plaster inspection of a large 2 storey home KDR on a P site and despite my warnings to the builder from the beginning there are no temporary downpipes installed, so I am just collecting evidence as it may be needed later.

My builder told me not many do concrete piers underneath of slab. Our builder and slab engineer has put at-least 20 concrete piers before doing slab which I believe is waffle slab. Property being built literally next to us are having significantly less concrete piers. How this can be possible as I would have thought their soil type etc. would be same as ours. I must say it's a house and land package though.
Looking to build a home in VIC.
Land titled in November 2017. Construction started in February 2018. Double storey 37sq.

Its a brand new Stockland estate so the land has been built to comply for any potential flooding and is sold as such plus the neighbouring slabs are 100mm to 150mm lower.…
