In November 2021, a pipeline dig up activity revealed a pipeline parting at SSGP ROW, suspected to be caused by geohazard. Geotechnica Sdn Bhd, in association with Wan Husin & Associates Sdn Bhd, was appointed to perform a geological assessment and recommend mitigation action.


Field assessment showed high deformation and active slope movement with signs of distress and geological structures such as fault, buckling, boudinage, tension cracks and water seepage. Kinematic analysis and XRD testing identified potential sliding, wedge and toppling failure, and revealed intense weathering and deformation. Immediate and permanent remedial works were recommended to prevent further deterioration.
