Hi
Was wondering if there are any issues building a raft foundation system on top of the building pad (similar to a waffle pod slab) rather than excavating the foundations into the building pad?
The pad would effectively have to built up to underside slab level with 200-300mm of suitable fill material and then the internal slab beams constructed through this material.
Not entirely sure of the reasoning behind this approach (although it will be easier to construct the internal beams through fill material rather than natural material) but this approach has been raised with us recently and was hoping to get some others thoughts.
The requirements of Figure 5.7 (c) would need to be adhered to also.
Regards
