The site of the reinforced fill slope is located at NENT Landfill. A 35m-high and 340m length embankment bridging two hilltops is constructed to retain future waste.


It is designed for stability on both west and east side as a standing embankment and eventually overall stability when waste will be deposit against the west face.


Construction takes the form of wrap around layers of geogrids extending from east face to west face with CDV fill.


The west face is lined with a green geomembrane for aesthetic purpose prior to receiving waste.

A fire resistance facing at the eastern face is necessary for reason it will be permanently exposed.


The height of the embankment varies from 6m to 35m and the slope angle is about 68 degree from horizontal.


The whole embankment takes the form of a curvature with large variation on base width from 20m to as lengthy as 56m, at the crest it becomes 6m the narrowest.


On the east face, the formation level is about 7m below that of the west face and the overall height becomes 42m maximum.
