About this product

The Steerable Rock System (SRS) is the auger boring market’s first steerable head designed to navigate not only solid rock but difficult fractured rock conditions as well. Engineered to operate in rock up to 25,000 psi, the SRS allows operators to keep bores online and grade even in the toughest ground conditions for an on-grade bore.

The SRS heads are designed to complete tough rock crossing in rock varying from 3,000 psi to 25,000 psi in strength.

Efficiency on the Job. Completes longer on-grade bores compared to other methods, at a reduced cost, while helping contractors complete more bores in a time-efficient manner.


Pipe is installed accurately in one pass, no need for a pilot bore.


No need to pull augers and go up the tunnel to adjust the steering, all steering adjustments are done from the safety of the launch pit.

Monitor. Check and maintain the line throughout the bore with twin line projection halogen lights enclosed in the steering head
