More Cohesion – Less Cohesion
This test can be used to estimate the unconfirmed compressive strength of cohesive soils.
Thumb Penetration Test
1-800-292-8525 or 811
Excavators must observe a tolerance zone compressive strength of cohesive soils.
The width of the facility on a horizontal plane, at least 18” on either side of the outside edge
If relocation is necessary, excavator must coordinate with facility owner/operatorUtilities Location
