If you need to move people or product through tunnels — square or round — call on Miller The Driller. We can tunnel just about anywhere — under railbeds, roadways or buildings, through hills in rock or dirt.

Tunnel casings can be concrete or steel. While recent tunnel projects have been up to 147" in diameter, we can handle tunneling in any size, for any purpose, and in any place. Our new rock head bores through solid rock in diameters to 66" with other sizes available depending on your project needs. Miller The Driller can design and install your tunneling solution.

As with any of our services, your project starts with expert planning and consideration of site conditions and characteristics. Miller The Driller then follows through with an installation that meets your needs.
