A prime water front site required extensive excavation and remodelling works to be undertaken to ready the building platform for a new residenital dwelling.
Grouting Services was awarded the subcontract to carry out the slope protection works over a total of 600sq.m of excavated face. A total of 300No permanent rock bolts were installed comprising 2-5m long BluGeo Powerthread K60 – 32mm GRP bar in a 150mm drill hole. BluGeo Powerthread K60 BGR bar was accepted as a cost effective alternative to the specified galvanized bar, and, given the close proximity to the sea provided enhanced durability.
The slope protection works proceeded in tandem with the excavation works and included the supply and installation of pyramat (high performance turf reinforcement), Tecco mesh and spike plates. The top boundary of the site was protected with the installation of a 30m Geobrugg rockfall fence.Contact Us +64 9 837 2510
