The client was seeking a solution for the ground improvement for the construction of a Reinforced Soil Wall for ROB 208 Arjungunj, U.P., India. The approach was designed for a maximum height of 10 m.
The sub-base soil in the area was weak with a low bearing capacity. But providing conventional solutions of soil replacement, stone columns, PVDs and other such techniques was not warranted as it would have made the structure commercially unviable.
Considering the technical parameters, the time factor, and economics, a StrataWeb® geocell engineered solution was finalized. Two layers of StrataWeb® geocells style SW 356-100 were proposed where the RS wall height was 10 m and up to 4 m. For ramp height, less than 4 m, a single layer of StrataWeb® was proposed. The local non-plastic soil was selected for infilling.
The use of StrataWeb® proved to be a rapid and successful solution, improving the bearing capacity to the desired levels. This enabled the construction of the RS Wall ahead of schedule.
