Creating two lines of concrete piles close to a building to enable safe foundations for a new construction, right on the lake front in Wanaka.
Using our new multishank rotopercussion unit , we have drilled 80 holes 1.20 meters deep and used thick grouts as a flushing medium.
Drill on Wanaka Lake front
In association with Downer Edi Works and Opus International, we have scaled and blasted 2 rock features from the 230m high face: Epsilon VI and the Lower West Column for a total amount of 35 cubic meters.
These features that are regularly monitored by Opus, were highly fractured and threatened the road and traffic below.
After the rock removal, we have drilled, installed, grouted and tested 10 rocks bolts (between 4.5 and 9 meters deep) at 100 meters high on the West column.
Also for reinforcement purpose, we then carried out a complete installation of a mesh on the Lower West Column, in a very overhanging zone. The location of anchors is carefully chosen to make sure the mesh fits well.
