You can't use that sample for anything as it's classed as a disturbed sample. They can check it for organic materials is about the height of it so waste of time.
When you do a borehole you use a hollow pipe/cone to perform a spt which is basically counting how many blows it takes to move a set depth. If it takes under 10 blows the ground makeup is very soft and on the other hand you can get over 50-60 blows and even refusal where the tool just bounces, usually when you hit rock. You can see on the logs above they have performed 2 tests, with 7 blows and 50 blows. So a massive difference in the bearing capacity of the ground in a few metres.
Did building control come out and look at your trial pit or just you and the digger man??
