The project on North Island Main Trunk line at Utiku for Kiwirail is complete. Over a 5 week period the geo team installed 51 GRP soil nails into the undercut face and then applied a fibre reinforced shotcrete layer on top of a layer of tecco rock fall mesh.

The 35mpa shotcrete had sufficient Forta-Ferro fibres to ensure the shotcrete attained an RDP toughness of 400J. Face drains, drilled drains and a sub soil drain along the top ensure the area is kept dry.

Tidiest geo project ever!
