This is a proud moment in Barbco’s 32-year history of driving the trenchless technology, horizontal boring and underground manufacturing industries forward with world class capital equipment and cutting-edge technology, according to a Feb. 23 company statement.

Barbco previously received a patent for its FlexBor tooling and technology in November 2019. FlexBor is a cost-effective, environmentally safe trenchless method. It is designed to virtually eliminate “frac-outs” and “inadvertent returns” that are often associated with horizontal directional drilling and the use of bentonite as a slip agent lubricant.
