• Drilling 5.4m electrodes in the level 3 basement of the building
• Supplying and installing specialised galvanized risers and draw-in boxes to accommodate 70mm2 XLPE cable to be taken to the ground floor level.

Installing the galvanized risers in the basement was particularly challenging due to the confined area.

Result: The project was completed successfully to the client’s satisfaction.
