We are currently going through tender process with Plantation Homes (Henley in QLD) and have been advised that due to our soil test results we need H Class foundations - 600mm waffle pod slab
We received our siting plan yesterday which shows a pad level of 56.8m and a finished floor level of 57.41m, and are wondering if it's normal to have the slab this high above the pad level, and if so, what it would look like when finished.
To put it in perspective, we need 800mm retaining walls down one side of the house - the slab will be nearly as high as the retaining walls...
Has anyone else had experience with a h-class waffle pod slab, and was it built 600mm above the pad?
