Rope access technicians in high-visibility clothing work on a steep slope reinforced with black geotextile fabric under a clear blue sky. Above them, onlookers gather by a railing on the crest of the hill beside coastal homes bathed in sunlight.

Tawa Slope Stabilisation

A slip above the Main Road in Tawa posed a threat to traffic. Abseil Access was awarded the project to install 53 rock bolts with a reinforced rockfall mesh to prevent further erosion. A purpose-built scaffold was constructed to work with a traffic deviation to reduce traffic disruption to a minimum. The anchors were installed on the slip and into the rock at 2.5m high by 3m wide spacing and up to 6m deep with 100mm diameter holes.

A timber water stop wall was then installed along the top of the site to divert rainwater away from the slip face. Finally, the area was covered with a layer of erosion control mesh reinforced with wire ropes. The works were completed on time within the 6-week timeframe and conformed with all the Engineers specifications and quality requirements.
