Horizontal Directional Drilling is a steerable guided method of Installing underground utilities (viz OFC, PC, Gas Pipe line, Water & Sewerage Pipe Line etc) in a prescribed bore path using surface launched HDD Machines.(Apollo, Vermeer, Ditch Witch, XCMG, Drilto, Goodeng, Dilong, American Augur, herrenknecht, etc). Apollo has created a niche in the small and mid-size segment and is doing rigorous and extensive work in the technical upgradations with the quality components in manufacturing of MAXI RIGS ( >45-ton Rigs). Recently, Apollo developed an outstanding Maxi Rig model A1200 which is gaining popularity especially for drilling in rocks by using the Mud Motor and other advanced tools. A prescribed boring is used when an open trench or open excavation is not possible.
