Horizontal directional drilling
Telecommunication & Site Utilities
Installation of fiber, telecommunications, septic systems, and site utilities for residential, commercial, and government projects.
Electrical & Gas Utility Installation
Underground installation of electrical conduit and gas lines for airports, highways, substations, and commercial developments in challenging ground conditions.
Water & Sewer Infrastructure
Installation of water lines, sewer force mains, and residential water meters for municipal, commercial, and subdivision projects across O‘ahu, Maui, and Kaua‘i.
Pipeline Replacement & Rehabilitation
We replace aging pipelines using trenchless methods such as pipe bursting, allowing infrastructure upgrades without major excavation or road closures.
Horizontal Directional Drilling (HDD)
Our core service. We install underground utilities without trenching, minimizing surface disruption. We can handle anything with our range of directional bores, ranging from 1" to 36" and above. No terrain is foreign to us.

THE PROCESS
01 PILOT HOLE
02 REAMING
We drill a small, guided pilot hole along a predetermined path between entry and exit points. Depth and alignment are monitored in real time to ensure accuracy.
The pilot hole is enlarged using reamers in stages until it reaches the required diameter for the new pipe.
03 PULLBACK
The new pipe is attached and pulled back through the bore, completing installation with minimal surface disruption.
WE HAVE EXPERTISE IN
UNIQUE GROUND CONDITIONS
Basalt & Volcanic Rock
Limestone, Coral & Coastal Formations
