The collection of representative subsurface samples is key to the development of relevant and accurate geotechnical evaluations and assessments. There are a wide variety of sampling methods available, and each is suited to a particular exploration method(s) and information goals. Oftentimes, multiple sampling methods will be utilized for a given project depending upon the nature of the subsurface materials and the scope of the proposed design. We have extensive experience with several common geotechnical sampling methods, and we have summarized the general purpose and procedure for each method and some their individual pros and cons.
