The prolonged infiltration of rainwater along the unconsolidated overburden material leads to the increased pore water pressure and resulted in failure along the slope.

1. Removal of slided material from retaining wall and repairing of damaged wall. 2. Removal of rock boulders and slided material occurring at critical angle from slope surface. 3. Provision form hill side drainage.
1. Unconsolidated overburden material (2 m) composed of unconsolidated parent rock mass intermixed with soil.  2. Prolonged saturation of overburden by rain water develop local hydrostatic pressure and reduction of shear strength resulting in failure.
