Wanted to consider a 2 step soil probe. Know the idea might be in circulation but I haven't researched at this stage possibly due to the complexity. I know with bore hole logging you can determine soil on site, others mention testing back at the lab as well. I wanted to consider ways of detecting on site based on cheaper and hopefully more efficient methods. One difficulty is rock crop below the surface, I know can be designed for but others mentioned the rock crop areas can be a great problem for soil design. I think most companies can tackle the potential situation.
