Client Reviews

Rockfall Mitigation in Virginia

I wish I had been smart enough to let you design the rock mitigation. You and your team turned in an excellent performance. The work ethic of your team impressed everyone on our side of the table. Most companies print a slogan on their company clothing. However, your folks demonstrated every hour that they “Work Hard or Go Home”. You sent us a world class construction team – thanks!

Rockfall Mitigation and Removal in Wyoming

Richard, I wanted to take a quick minute and thank you and Courtney and the awesome crew that you sent here to take care of our huge rock. Courtney, John, and Andrew are some of the hardest working people I have had the privilege to be around. Their attention to safety professionalism, and never quit attitude was amazing to watch. Even when things did not go our way they were committed to finishing the job. I appreciate you sending these great guys to help us out and look forward to the opportunity to work with you again in the future.

Rockfall Mitigation Support for Mining Operations

As told by GSI Rockfall Division Director: “I am at the [mine] now and the truck with the equipment from the warehouse just arrived. Environmental issues are extremely important in the mine so any equipment arriving on site has to be pressure washed and cleaned. Although they ask this of every contractor that arrives on site, they always seem to have to do a secondary washing here with their own people (just the way it always seems to turn out). Our people at the warehouse did such an awesome job of cleaning and taking the client’s concern to heart that they do not have to do a secondary cleaning and complimented us for such a great job.
