This paper presents the rehabilitation of an existing reinforced soil wall which comprised a welded wire mesh facing and GeoStrap as soil reinforcement. The wall was constructed in 2019 and failed following heavy rains in June 2022. The failure was characterized by a collapse of the top portion of the structure while the bottom portion continued to stand although in distressed condition. In the stretch where the top portion of the wall collapsed, the functional road caved in leading authorities to impose road closure to safeguard commuters. The conventional rectification approach to rectify such a structure is to undertake complete dismantling and rebuilding. To restore functionality of the affected road stretch, an attempt was made to strengthen the remaining reinforced soil wall, rather than complete dismantling and rebuilding. The strengthening of the existing wall proves to be an economical alternative to the conventional dismantling and rebuilding approach. The strengthening of uncollapsed portion wall was accomplished through soil nailing with TerraNail®. This paper presents the detailed problem description, the design methodology adopted for nailing in the existing reinforced soil structure and a cost benefit analysis of adopting strengthening in lieu of dismantling.
