N4 Karino lateral support

The N4 Karino lateral support project, during which Terra Strata installed lateral support covering an 880m2 area, was undertaken over a ten-week period. The permanent lateral support project, undertaken for Raubex, covers the cutting for the N4-Karino interchange just outside Nelspruit. The project scope included the drilling of a combination of 485m of soil nails and 580m self-drilling anchors (SDA). The extremely difficult and irregular geological conditions encountered on site necessitated the spraying of an additional 145m3 shotcrete to fill the overbreak and collapsing materials.
