Removal of debris and construction of lined hillside drainage to arrest further toe erosion. Channeling of surface drainage away from the affected slope to stop from further deterioration. Immediate sealing / covering of the exposed overburden on the roa
The over-riding factor for the landslide is the super-saturation of fill material through prolonged infiltration of unguided surface water into the loose overburden soil observed along the crown area thereby drastically increasing the pore water pressure
