The client identified a high priority site that required significant stabilization measures. The goal of the project and subsequent work was to ensure stability of a steep slope above a busy railway line. We supplied the necessary materials and manpower to collect drains and install the manholes and discharge pipes. The client’s report describes the project:

Railway Installation & Horizontal Drain Work
Railroad, British Columbia
“The main water seepage was approximately 15 m above the track and it was impossible to drill in from the front face. A more feasible approach involved pioneering a cat trail in from the ravine to the east, setting up near the elevation of the springs and then installing the drains starting parallel to the slope and fanning back into the slope. The horizontal drains were collected and connected into the manhole; from the manhole, with water discharging towards the east ravine and existing culvert.
The Aardvark drill system provides for drilling horizontally by the conventional rotary method, and then inserting PVC slotted screens inside the drill rod to the full length of the hole. The drill rod slope angle was set and varied from drain to drain at 0 to +8 degrees. All 12 drains were drilled from two drill setups.”
