The previous moisture conditions, trees, fill etc. may be playing a secondary role but from what you've posted it just 'feels' like something has been missed somewhere and that is what needs to be found. Reading over the past posts, the attention has been on leaking pipes, water coming into site, poor drainage etc. which is understandable. Just curious, has the house wall cavity drainage (if present) been discounted yet? Weep holes functioning, no irregularities with relative heights of slab checked out? This would have required holes drilled through the external walls and a look around with pinhole camera. If slab construction possibly dubious someone should also check that concrete hasn't been lost externally into the rolled fill around deepened detail at front-will anchor slab if lost 'unseen'. Checking the above may not reveal the answer but are cheap and simple to do and will provide more information which seems a bit short at moment. Currently you have gained enough information for each party to deny liability and are awaiting a fix without being able to clearly define the cause. Understandable that you are over it. Have look at your house plans and you will probably find that brick articulation joint has been missed. Maximum allowable spacing is 6M or 5.5M for a wall with window… 17 20675 Are they stumps or screw piles ? How much fill is there, is the site a class "P" ? A "H2" site is not supposed to have stumps it is supposed to have grid beams according… 1 7221 House movement is always a potential problem and there is a cause.
