our environmental consulting firm has been working nearly exclusively with GSI for over 20 years. GSI has always been able to meet our needs in the areas of subsurface soil sampling and assessment, vapor and groundwater well construction, well permitting and abandonment, surface completion repairs and upgrades, and general small construction tasks.
Their drill rigs are well equipped, in good condition, and staffed by helpful, competent operators and helpers. In addition, the GSI management team often comes up with innovative methods to solve the unusual situations that arise from time to time in the field of environmental and geotechnical consulting.
GSI is our “go-to” drilling contractor to get the job done in an efficient, cost effective manner.
“GSI was able to accommodate our project with a limited access rig in a timeline that was demanding. Their ability to expedite mobilization and safely perform the borings in a timely manner was greatly appreciated. Additionally, their costs were not prohibitive considering the circumstances. We will continue to rely upon GSI for our drilling services.”
