Landslides are major natural disasters. It affects the ecosystem and results in economic loss. The Konkan region of Maharashtra, India, also experiences this problem every year. To prevent such disasters Slope stabilisation techniques are used, among which the retaining Structure provision is one of them. Most of the time, permanent RCC earth-retaining structures (ERS) is provided. These structures are constructed for a total serviceability period of 30–60 years but generally, in most of the cases in lateritic soil, they cannot withstand their total serviceable life. To find out the reasons for failure and to increase serviceability, a detailed investigative study of engineering geological and geotechnical properties was conducted to assess the serviceability or structural safety of cantilever earth retaining walls at Dasgaon and Sahilnagar from Mahad Tehsil, Konkan region, Maharashtra, and the preventive Measures resulting from the failure of cantilever ERS are discussed
