The soil report has identified a M-D class soil which is as expected and typical of the area. M means Moderately reactive clay or silt sites, which can experience moderate ground movement from moisture changes. D means that the Depth of the expected movement is greater than 3m.
The reactivity (shrinking and swelling) of the clay can have a significant impact on the footings/slabs of a buildings foundation which need to be designed to counteract the movements of the clay soils, otherwise damage (cracking) of the house may occur.
If the soil report had returned a classification of H (Highly reactive clay sites), E (Extremely reactive sites), or P (Problem sites) our foundations/slab would be far more costly. So good news!
The bore logs did pick up some shale fragments but they were pretty deep, and they didn't find any rock. If this is all that is encountered when digging then we shouldn't have any costly issues, but you still never know what you will find.
It has also been determined that the house will sit well in the specified location, and the splits will be around 860mm (5 steps) from the lower to middle level and 670mm (4 steps) from the middle to upper level.
Now that we know the levels of the house the roof can be designed. A 3D version of the house and an updated floor plan will follow shortly.
As soon as we have finalised the main details of the house it can then be submitted to the local council for approval. Way hay :)
