Two techniques must be used in all excavations going deeper that five feet, according to OSHA, to determine soil type. Classification of the soil is necessary to properly apply cave-in protection techniques. Simple qualitative analytical methods that do not require instrumentation and that are commonly used to determine soil types include:
What are visual examination, the thumb penetration test and the plasticity (ribbon) test?
