Hi, I would like to ask if anyone can advise.
As I can’t wait for work to excavate to formation level, current RL111, my earth mat at RL101. How can I accurately test and obtain soil data from RL101 (approx. 9m below) and RL91?
I read wenner method provides apparent resistivity. If I need 10m, my prob spacing needs to be 10m apart giving me C1 and C2 probe at 30m apart. IEEE81 spells 300% to have tight margin of error.
Hope someone here can advise. Thank you.
