Reinforced Soil Wall with discrete concrete panel as facia and Double Twisted Hexagonal mesh as reinforcement was selected as the system. Square discrete concrete panel were used as facia, some special end panels and corner panels were also used. The connection between the panels & reinforcement was done by embedding the small length of reinforcement in the panel during the casting of panel and then lacing the required reinforcement length with embedded small length of reinforcement. Zinc + PVC coated Double twisted hexagonalmesh was used as reinforcement. As the founding soil has low bearing capacity, it was suggested to replace the existing soil with good frictional fill. Replacement was up to 1m depth for wall height of 6m to 12m and 0.5m for wall below 6m height. The maximum height of wall was 12m and varies up to 3m. The reinforced soil wall design was carried out according to British Standard 8006. The live load surcharge was considered as per the Indian code (Indian Road Congress 6 Class AA loading condition). The structure gives a very pleasing appearance and well appreciated. Some field studies and lab studies were conducted during the construction to understand the suitability of the system. The field studies were to check the stress-strain behavior of the reinforcing mesh at different levels and the global deformation of structure as a whole. The lab studies included the analysis of mesh reinforcement under different loading and end conditions while the rupture and pullout strength of the material were being tested.
