As urban infrastructure becomes increasingly congested and environmental regulations tighten, traditional opencut trenching is often no longer a viable option for underground construction.
Enter the steerable horizontal directional drill — a technology that has fundamentally transformed how contractors install critical utilities. By combining raw mechanical power with pinpoint accuracy, steerable HDDs allow operators to navigate complex subterranean pathways with minimal surface disruption. The DRY BORE-4 from RODDIE Trenchless Equipment takes steerability to the next level.
The defining characteristic of the DRY BORE-4 is its dynamic steerability. Using a specialized drill head equipped with a modular rod turner powered by a Milwaukee Tool cordless ratchet, the unit puts drilling precision in the hands of the operator.
“Past steerable directional drilling systems simply wouldn’t steer properly because they use a pipe wrench to rotate the rod,” says Rod Herrick, RODDIE founder and inventor of the DRY BORE-4. “This system allows for precision directional drilling without the mud and mess.”
The steering ability of the DRY BORE-4 lets crews steer the bore path to curve around existing underground utilities, dive beneath waterways and thread through challenging rock formations. It is designed to install underground service lines up to 4 inches in diameter. It provides 3,000 ft-lbs of rotational torque and 20 tons of push force. These capabilities make it ideal for expanding or replacing aging water mains and sewer networks, which often requires navigating dense urban grids or sensitive ecosystems. It can be used to install potable water lines, force mains and even precision gravity sewers beneath highways, rivers and commercial districts. This trenchless approach prevents massive traffic disruptions and the costly surface restorations associated with ripping up miles of asphalt. Other applications include telecommunications and broadband lines, power distribution and gas pipelines.
“Our research and development with this unit was a 15-month process,” says Herrick. “Basically, we saw a need in the industry because, in our eyes, steerable HDD tech was falling short. The testing we’ve done with the prototype of this unit proves it answers the call. To see it in action, simply search ‘DRY BORE-4’ on YouTube.”
The steerable horizontal directional drill is an indispensable asset for modernizing infrastructure, Herrick says. As the demand for reliable, upgraded underground utilities grows, according to the maker, the precision and efficiency of steerable HDDs will continue to drive the future of alternative excavation.
