Micro Piles & GCS® Wall at Waitomo

Micro Piles & GCS® Wall at Waitomo

The project involved the design and building of three retaining walls to remediate slips and increase the road width. GeoStabilization’s geotechnical design involved installation of micro piles and construction of a reinforced concrete footing. Once the footing was completed, soil nails and rockfall netting were placed in the embankment.

A Geosynthetically Confined Soil® (GCS®) wall was then constructed and finished with a masonry block facing. All construction works were undertaken under Level 1 Stop / Go traffic control, as the road was too narrow to enable a single lane of traffic with construction machinery.
