Horizontal Drilling, Ground Anchors – Rocks Road

Location
Rocks Road, Nelson

Client
Fulton Hogan

Drilling Project Brief
Drilling and installation of ground anchors for a retaining wall. The project required the drilling, installation, grouting, testing, lock off and post grouting of 30 ground anchors of varying size, to anchor a replacement wall.
The original wall suffered significant damage in Decembers rain event, and required replacement. We used Reid products, RB32 and RB25 single strand bars for this application.

Drilling Project Challenges
Extremely tight, restricted access to site.
Steep terrain had a 30m drop onto the busy State Highway 6.
All drill holes located up to 3m below the road edge.
All staff on lower section were required to wear ‘fail arrest harnesses’.

Result
Despite the exceedingly difficult access, and the potential risks from several other hazards this project progressed very smoothly and was completed within time and budget.
