INTRODUCTION

Landslips pose a significant challenge to New Zealand’s extensive roading network, especially in areas like Wellington where an average of 1100 landslips occur annually. These natural disasters disrupt local communities, making it crucial for roading contractors to promptly clear landslips and secure the area temporarily until a long-term solution can be implemented.

CASE STUDY: LIVEABLE STREETS AUCKLAND

In early 2022, heavy rains triggered landslides in Whitford, Auckland, posing an immediate threat to properties and nearby power/utility lines. The Liveable Streets joint venture, comprising HEB Construction and Higgins Contracting, needed a fast, reliable solution. Interbloc’s Precast Concrete Wall System was chosen over timber and gabion baskets due to its rapid deployment capabilities. In just four days, 337 blocks were installed, creating a 2.4m high and 20.4m long protective wall, ensuring the safety of residents and the community.

In conclusion, Interbloc’s Temporary Slip Protection wall system stands as a testament to innovative engineering, providing not just a wall but a shield of safety for communities affected by landslips. Its speed, reliability, and sustainability make it an invaluable asset in the face of natural disasters, ensuring the swift recovery and security of New Zealand’s vital roading infrastructure and the communities it serves.
