Does that mean I should be concerned we have P soil....? Or not too worried because the footings will be in the S soil?

Does that mean I should be concerned we have P soil....? Or not too worried because the footings will be in the S soil? I dont know if this will help or not... Our site is H1-P (Highly reactive soils, but classed as a P site due to 300mm of fill on top) The report stated the only reason it was a P site, was due to the fill. There was a compaction certificate provided and our total footings/site works came to $18,000 in the end. We originally budgeted around $23k, so we were happy Thread: viewtopic.php?f=31&t=66299 Slab: 16/6/14 Frame: 4/7/14 Roof: 22/7/14 Lock Up: 20/8/14 Fixing: 26/8/14 PCI: 9/10/14 Handover: 20/10/14 Re: Class of Build Sites 8May 12, 2014 5:38 pm Brooke_n_Ron Hi, I just received my soil test results and its really confusing, they came up as "P: Due to presence of fill" then underneath " reactivity S classification" - then they went on to say that the presence of fill was app 300mm deep. Does that mean I should be concerned we have P soil....? Or not too worried because the footings will be in the S soil? The way I'd read that is somewhat similar to yourself. The reactivity of the soil is S, and the only concern they have is the amount of fill that could be Problematic, i.e. P. The person who organises the slab has it engineered based upon the S soil taking in to account the depth of the fill. On our sloping block our soil test came back with P representitive of H1. The P came about because of the trees in the area of where we wanted to have the house built, and that it could have been problematic if the roots weren't removed, as in they'd rot away eventually creating a subsistane of the soil under the slab. Our site prep including the excavations, the shredding of the trees, and the gravel driveway cost us around $19,000 ... I guess it would've cost me a hell of a lot more if I wasn't a owner builder, and had it done by a cookie cutter building company. Owner Building at Jimboomba Woods in Logan City Qld.

Hi Brooke-n-Ron was the fill sand or clay and well compacted, also was the natural soil under the fill natural sand ? If you use a raft slab you can deepen the beams through the fill Re: Class of Build Sites 10Jun 03, 2014 5:49 am When a sloping site is excavated the soil profile is altered. One can often get a soil test re-done and the site reclassified. The real issue is what is the house sitting on?

The concern with the tree removal is the rebound from the clay as it re-hydrates and causes the clay to swell generally the engineers are not to concerned with the roots rotting unless it is a mass of roots or organic layer because the slabs can span distances under your slab e.g. think about the plumbing trenches under you slab Hi, We are looking for a builder that can build a small home (smaller length) on a sloping site.
