Tseung Kwan O Area 137 Fill Bank Clay

This soil was designated as public fill within the Tseung Kwan O Area 137 Fill Bank.

"...Construction and demolition (C & D) materials are a mixture of inert materials (e.g. soil, rocks and broken concrete) and wastes arising from construction activities. Local construction industry produces about 14 million tonnes of C&D materials a year." (Port Works Division Civil Engineering Department, 2001)

"...At the moment, most of the inert materials (also known as public fill) are reused at reclamation projects which hitherto have been the major outlet for these materials. However by mid-2002, most of the approved reclamation projects will no longer be able to absorb further public fill." (Port Works Division Civil Engineering Department, 2001)

Basic on site testing determined that the clay content was sufficient for making activities. A large sample of fill was transported to the University of Hong Kong Division of Landscape Architecture, where soil processing is underway.
