As part of our house planning adventure we have had to have a soil test done on the house site. This is quite an expensive exercise, but it is essential for council approval. As well as ticking off another box for council, this test will give us information about how reactive our soil is (this just means how much it swells or moves during rain or extra dry conditions) and will help us plan the foundation design. We are hoping for class A soil (which is of course the most stable classification) because this will make our foundation designs simpler and less expensive.
The soil test guy came out to the humpy a little late (even with Google Maps we can be a bit hard to find) but happy and friendly. He was met by four dogs, a sheep and various screeches from inside, which he took in his stride. I showed him the site and he paced it all out, marking the drilling spots with a neat little orange cone.
The drill rig on his ute was fascinating to watch and he was very professional. He even made some piles of soil at different depths for me to see the difference in soil types.
He also made mud balls for me to see if we had enough clay for cob mixes.
Eventually the test came back, and guess what? We have a P rating. Yes; that is P for problem site. The most expensive rating when it comes to building, because now we will have to have a beefed up foundation. Oh well, on with the plan, slowly but surely.
