Penhoek Pass - Slope Stabilisation
Client: Group Five Civil Engineering
Engineer: Worley Parsons
Location: Eastern Cape, South Africa
Project Period: April – October 2014
As part of the National Route 6 upgrade through the mountainous Penhoek Pass, Fairbrother Geotechnical Engineering was appointed to provide slope stabilisation and rockfall protection for newly widened road cuttings.
Scope of Work:
Lateral Support:
4,125 m² of fibre-reinforced shotcrete
446 tensioned rock bolts
346 self-drill anchors
Rockfall Protection:
200 m of 500 kJ energy-rated Geobrugg rockfall catch fences installed at the crest of slopes
Project Challenges:
The work was carried out under harsh weather conditions, including sub-zero temperatures and snowfall during the Eastern Cape winter. Despite these challenges, Fairbrother successfully delivered a durable slope stabilisation system ensuring long-term safety for road users.
This project demonstrates Fairbrother’s capacity to execute technically demanding geotechnical works in remote, high-altitude environments.
