Professional Drilling PDF Print E-mail

Professional drilling has been the core of our business since GSI was established in 1973. GSI maintains a fleet of 12 drill rigs of various sizes and types with full support equipment. In addition, our professional drilling crews are OSHA Safety trained. We routinely provide professional drilling in support of other engineering and environmental organizations during the implementation of projects. Benefits of our professional drilling services include time-efficient scheduling and the ability to mobilize (within hours) the appropriate equipment and crew. As technical experts in the industry, we offer our clients innovative technologies such as cone penetrometer testing with our Mobile In Situ Lab (MISL), facilitating immediate results through on-site data analysis and reduction.
