Adoption of New and Green Construction Materials in the Landslip Prevention and Mitigation Programme

As technology advances, the Geotechnical Engineering Office of the Civil Engineering and Development Department has endeavoured to take every opportunity to improve our geotechnical standards and services through technical development and innovation. It is also our policy to seek continuous improvement in the Landslip Prevention and Mitigation Programme, our long-term rolling programme in reducing systematically the landslide risks of man-made slopes and natural hillsides affecting existing facilities. One of the key areas of technical development is the adoption of new and green construction materials for use in the design and construction of our landslip prevention and mitigation works. This paper summarises our work on the technical development and application of self compacting backfill material and ground granulated blastfurnace slag grout mixes as part of our contribution in shaping a safe, green and sustainable city.
