NAMI has developed a collapse-free backfill material which is self-leveling and soil-like, being low strength and self-compacting.
Road and pavement damages are frequently encountered due to incomplete compaction of the underlying soil. NAMI’s backfill material provides a solution to overcome difficult underground situations, such as trenches with congested utilities, where backfilling or compaction of the conventional backfilling materials cannot be conducted satisfactorily and thus causing unsatisfactory permanent reinstatement of the pavement above.
As a Materials Expert, Nano and Advanced Materials Institute (NAMI) has a strong portfolio of innovative technologies to support and collaborate with the industry, offering frontier-applied research on advanced materials as well as technology transfer for commercialization success.
NAMI, incorporated in 2006, is designated by the Innovation and Technology Commission of the Hong Kong Government as a Research and Development Center for nanotechnology and advanced materials. NAMI undertakes and provides support for market-driven research in nanotechnology and advanced materials, and strives for commercialization of the technologies to benefit the industry and the society at large, as well as re-industrialization to promote the economic growth and sustainability of Hong Kong.
