Advanced installation solutions to optimize impact and minimize cost.
Creating Safe and Efficient Solutions With Our Qualified Team
We understand that our customers are challenged with a multitude of problems when developing and installing pipelines. Our HDD Services minimize disruptions to traffic, require less site restoration, and can be safely installed through protected areas. Our highly trained team members adhere to strict HDD anti-collision standard operating procedures, while utilizing top line equipment for best results.
HDD Services Include:
- Gas, Oil, Water, Sewer, Electrical, Communications
- Steel, HDPE, or FPVC
- In House: Design, Welding/Fusion, Testing, and
Tie-In
Horizontal Directional Drilling Process
Prior to the start of drilling operations, all subsurface utilities are identified, and existing utilities are manually exposed before drilling past the exposed utility. Once all obstructions are identified, our drilling crew begins drilling the pilot bore by utilizing a directional drill bit and locating technologies, establishing inclination and azimuth, enabling the navigation of the bore path. The driller will start at the designed entry point and continues drilling through the designed drill path until the exit point is reached. Drill cuttings and fluid are returned to the entry point throughout the pilot process. Following the pilot bore, reaming begins. Reaming involves swapping the directional drill bit for a reamer tool with an array of cutters and drilling fluid jets. This tool is rotated through the pilot, gradually increasing the diameter of the hole until it is sized properly to fit the pipeline or URD conduit.
Finalization and Installation
Our team of in-house welders and fusers fabricate the pipeline or conduit near the exit point. Once the enlarged boring or drilling is complete, the pipe is pulled from the exit point on a swivel through the pilot hole into its final position. The final step is to tie-in the pipe to the existing infrastructure. Our walk over guidance system works for any length up to 60’ deep, with wire-line guidance for any depth and length.
Our in-house HDD Fleet includes the following:
- 36×50 & 40×55 Rigs – Capable of drilling 2″ – 8″ pipe 1000′ or more
- 10×120 Rigs – Capable of drilling up to 24″ pipe on short runs (up to 16″ on longer runs and depths)
Our professional drillers use best in class equipment and technology to ensure optimized results and the safest solutions for our customers.
