Bortech’s Down-the-Hole (DTH) Hammer System
One Method for an Unpredictable Underground
When underground conditions change, your drilling method shouldn’t have to. Bortech’s DTH Hammer System addresses unpredictability with a single, adaptable approach.
Designed to advance steel casing through challenging ground conditions, our system combines DTH technology, casing advancement, remote operation, and automated control into one specialized solution.
Built for the Ground You Actually Encounter
Traditional drilling methods often depend on predictable subsurface conditions. Our DTH
Hammer System is designed for adaptability.
With diameters from 8 inches to 48 inches and lengths up to 300 feet, it fits a variety of utility
and infrastructure applications.
Conventional soils
Cobbles
Boulders
Shot rock
Hard rock
Highly variable subsurface conditions
Engineered for Efficiency From the Start
Project efficiency begins before the first foot of casing is installed. Our system allows rapid setup without the need for additional infrastructure.
With an above-ground power source and remote-control operation, personnel can work safely from a distance.
The 21-foot jacking pit accommodates 10-foot casing segments, streamlining installation while minimizing the operational footprint.
Designed to Advance Casing—Not Just Drill a Hole
Our DTH Hammer System combines drilling and casing advancement effectively. A welded
casing shoe secures the starter casing and prevents the pilot bit from leading the casing.
The system's design eliminates the need for exterior grouting and reduces reliance on drilling
fluids.
Precision Matters Underground
Getting through the ground is just part of the job. Maintaining the precise line and grade is crucial for successful installations.
Our hydraulic line-and-grade adjustment ensures the intended trajectory is maintained, reducing complications downstream.
Smart Hammer Technology for Difficult Ground
The DTH Hammer System is engineered to direct energy efficiently:
Adaptive Hammer Force: Dynamically adjusts to optimize casing advancement.
Minimized Radial Vibration: Directs energy straight into the rock for efficient
penetration.
Spiral Flush Pilot Bit: Prevents ground charging and supports consistent advancement.
Closed-Face Bit Design: Maintains casing integrity throughout drilling.
A More Controlled Approach to Underground Construction
Bortech’s DTH Hammer System combines several capabilities:
Adaptability: Works across a broad range of soil and rock conditions.
Precision: Maintains intended bore trajectory with hydraulic adjustments.
Efficiency: Streamlined installation process with rapid setup.
Safety: Above-ground power and remote operation enhance safety.
Rock Penetration: Provides power for challenging formations.
Reduced Reliance on Drilling Fluids: No bentonite needed for lubrication.
Casing Integrity: Prevents ground infiltration during drilling.
