This project involved upgrading and widening an existing national highway in Odisha, India. The embankment slope lengths were as long as 16 m with slope angles as steep as 40 degrees. At some locations, concrete toe walls were constructed. Slopes of these embankments required protection against erosion due to rainwater runoff.
In contrast to constraints of the conventional system, the StrataWeb® slope erosion system overcomes these challenges. The style recommended for this project is SW 660, which was to be infilled with vegetated soil. Geocells are recommended as an appropriate solution by relevant codes and guidelines and are an effective way to protect the soil along a slope. The infilled geocells provide a stable layer of confined material over the slope surface. They foster vegetation growth to provide a green surface which also protects against erosion.
The use of StrataWeb® not only saved up to 5% of the cost compared to the conventional solution of stone pitching but also the installation was also 5 times faster due to the ease of StrataWeb® transportation and use of locally available and cheaper material.
