The Basics of Directional Drilling

HDD, or horizontal directional drilling, is drilling at a horizontal angle with the ability to change direction to reach a specific target. At Pipeshark, we use this efficient and versatile process of trenchless repair and trenchless pipe replacement in Philadelphia, PA for extensive projects in a wide variety of locations.

What Is Horizontal Directional Drilling?

Directional drilling is a method of trenchless sewer replacement in Philadelphia, PA that uses a horizontal boring machine to create a pilot hole. Because the angle of the boring head is adjustable, the method can also involve changes in direction to avoid underground obstacles.

As the pilot hole progresses, sections of stainless steel drill-rods are added behind the boring head. Once the boring head comes out on the other side, a reamer is added to the assembly, which makes a return trip, clearing and even expanding the diameter of the hole. The process allows for pulling back sections of pipe for utilities like gas or water or even large-diameter storm and sewer drains.

Real-Time Control

Among the more recent innovations for HDD is a real-time guidance system, initially used for big rigs. The system is portable enough to reassemble and be used to conduct trenchless sewer repair in Philadelphia, PA from difficult-to-access areas, such as basements.

Benefits of Horizontal Directional Drilling

Because it’s trenchless pipe repair in Philadelphia, PA with no excavation, HDD has related benefits:

  • Faster completion times with reduced labor costs
