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?

Shouldn't that read 56.8cm?? 56.8m would be a seriously high slab.   31 May 2007 1,041 Member Re: H Class Foundations 3Aug 22, 2007 11:41 am  3timesbuilda" 56.8m " Shouldn't that read 56.8cm?? 56.8m would be a seriously high slab. That would be 56.8M above sea level. So his actualy slab is 57.41-56.8 = 0.61m high. Meaning his slab will be 610mm above ground level.. almost as high as his retaining wall. Re: H Class Foundations 6Aug 22, 2007 3:38 pm That 'waffle pod slab'. One builder (Nu-Era) said that it's made out rigid form (what we get with TVs and so on). He also said that it will get rotten eventually and leaving a gap.
However, all most all the big builders are having waffle pod slab. Anyone got any thought on that? -devank Re: H Class Foundations 7Aug 22, 2007 4:40 pm As shown here, the dimension is about 1100mm x 1100mm for each waffle pod.

There are 2 version of images, you can only link the smaller one, not the bigger one.... Must be something been set on the blogspot.com which blocks all references to the bigger image... 25 Jul 2007 206 Bronze Member Re: H Class Foundations 10Aug 22, 2007 11:37 pm  damohave been in touch with the builder, and received an amended siting plan showing finished slab level of 57.185m, so a 385mm slab, which seems much more reasonable...  Yeah thats sounds about right. I would say that is about our slab height on waffle pods. our situation was a bit of a guinea pig in that structural work by the previous builder was defective and the house was almost completed, and our structural engineer… 1 4347 I am not sure whether Perth has its own way of doing things in regards to this. Most of Perth has class A (sandy soil), except for some areas near rivers or hills. 2 2402 I don’t think so as the floor area over 300 square meters then it is class 3…. 12 11437 |
