HDD Secunda (Rock Drilling)

The project consisted of 2 crossings with varying ground conditions from hard to rock formations. We established our American Auger DD-10 and Straightline Rock Eye Hammer.

We completed both crossings with the second crossing already having a tie-in point built. We achieved the crossing with great accuracy ending up exactly where the tie-in point was opened for the new HDPE pipe.

The void between the bore and pipeline was grouted after the installation of the new HDPE water lines.
