Tri State Trenchless, LLC  provides horizontal underground installation of steel and concrete pipes, for utility and drainage projects, up to 12 feet in diameter.  We provide auger boring and tunneling under highways, runways, railroads and waterways that, for logistical reasons, are unable to be closed for construction.  Our dry bore method has very little overcut which provides stability to the structures that we are boring under.  In our industry there is no one size fits all method to accomplish a project; therefore, we have to adapt to any soil conditions from sand to solid rock.  Our experience in all soil conditions lets us easily adapt to our location weather its 30 feet below sea level or a mile above sea level.  The ground determines the method used and we will do whatever it takes whether it be an auger bore or even hand digging.  Our tunneling machines, for good conditions, range from 42 inches to 144 inches, and we provide Micro tunneling for extreme situations and saturated grounds.


The advantage to our services is that we can successfully perform with little to no disruption to soil surface and traffic. Safety on the job is our top priority. Our industry is regulated by many agencies such as OSHA, EPA, MIASH and FMCSA as well as local agency regulations. We are a member of PICS Auditing System which verifies our safe working practices.  We are fair, honest and hardworking and we have never not finished or walked off a project.  Many companies do what we do, we just do it with higher accuracy and precision.
