Team TTI getting ready for next week today. Loading up our Eijkelkamp CRS 140 sonic and our dozer with the rear winch. They will be drilling on a earth dam next week over the slope. We will winch the drill over the slope with the dozer. Then the crews will sonic with our 4"x6" system to the top of rock. They will take sonic samples as well as spt's and shelby tubes to depth. Then set nested piezometers. Team TTI hopes everyone has a great weekend and a blessed upcoming week.

Team TTI hard at work in these cold tempatures. Proud of all our drill crews no matter what piece of equipment they are running. They can be on the specialty drilling crews with diffucult access like in the first pic. Running one of our Acker Kodiak's in the mountains of WV. To give reference of where their drilling, that is the New River Gourge bridge in the background. All our crews weather it's geotech, environmental, specialty or sonic drilling they get the job done. They battle the elements and daily battles and come out on top. Great job team TTI. Keep up the good work and remember spring is right around the corner.
