Tunnels, Bores, and Directional Drilling

Auger bores, Tunnel Boring Machines (TBM), Microtunnel, and Horizontal Directional Drilling (HDD) capabilities have helped eliminate obstacles that could otherwise impact a project. Additionally, the low impact installation is often attractive to owners and engineers, minimizing the inherent economic and social cost of complex construction environments. This work is handled by BTrenchless, a Division of BTC. 

Our services include:

Auger Bores up to 72" in diameter 
TBM from 51" to 130" in diameter 
Microtunnels from 48" to 120" in diameter 
Pipe-jacking up to 120" in diameter 
HDD from 2" to 36" in diameter
