When some builders decide to first dig under the ground where the slab is going to be laid to install utility pipes etc, and do not compact the soil properly before pouring the slab, one can expect huge problems later on. My house level dropped years later exactly where these pipes were laid. The waffle pod slab must be laid on hard compacted soil. The excuse of the reactive clay soil problem is not the entire story. The builders mistakes are being hidden by technical arguments related to soil type.
All comes down to the type of soil you are putting the slab on. Should only be used of relatively flat land, good drainage. I would not recommend waffle pod on reactive soil.
this bloke obviously has no idea what he's talking about, according to AS2870 residential slabs and footings standard, a conventional stiffened raft slab has a slab thickness of 100mm, and a waffle slab has a thickness of 85mm. Get your facts right from an actual engineer like myself

Is raft Slav better for reactive P class soil ?
@@karanmehra4911 you can use either, but it needs to be designed to accommodate the heaving. Usually need to see what the geotech report recommends
