SUBSURFACE EXPLORATORY INVESTIGATIONS
Exploratory drilling to collect deep rock and soil samples so we can understand what cannot be seen, but must be evaluated and considered.
All sampling methods are conducted in accordance with applicable ASTM standards, and our drilling team brings decades of drilling experience and state-of-the-art specialized equipment to every job site.

AGILE DRILL RIGS ENABLE SWIFT PROJECT STARTS
AOG’s fleet of ATV-mounted CME-55 drill rigs give us superior access to challenging terrains and difficult-to-navigate conditions. This means our skilled crew can begin projects quickly, without the delays associated with conventional truck-mounted equipment that requires dry ground to operate.
