Horizontal Directional Drilling (HDD) is used for installing telecommunications and power cable conduits, water lines, sewer lines, gas lines, It is used for crossing waterways, roadways, shore approaches, congested areas, environmentally sensitive areas and any area where other methods are more expensive or not feasible.
The machine is started above ground, drills down to the desired depth and then steers under the crossing. Once the pilot bore is completed, a reamer/backreamer is attached to the drill stem string and pulled back, enlarging the bore wall to easily accommodate the product wire, conduit or pipe, which is then pulled into place.
A very good job, extremely well done... everything was left much cleaner than on arrival. If the rest of our dealings with Powerco are equal to the service provided by Paneltec, we are all on a winner.
