SH1 Slip 3 Kaikoura
A major slip developed above SH1 just south of the Kaikoura Airport because of the 2016 7.8 magnitude Kaikoura Earthquake. The head scarp was over 60m above the state highway and over 90m across at the toe of the slip which consisted of friable soil and rock overlying a highly fractured greywacke bedrock.
The slip required around 3500m2 of actively stabilized TECCO G65/3 mesh with over 600No. 40/16 hollow bar DCP anchors installed under a grout flush to 6-9m in depth.
