On Nov. 5, Barbco Inc. co-owner Anthony Barbera was issued US Patent No. 10,465,460 for the FlexBor technology. The FlexBor system features an encased bore that virtually eliminates the threat of frac out and can be used in combination with horizontal directional drilling (HDD) or auger boring methods. The FlexBor system uses air flow to remove spoil, eliminating the need for slurry and reducing disposal costs. The pit launched system can reduce the entry angle associated with longer HDD crossings, thereby reducing the length of the bore.
