StrataWeb®: An Innovative Solution for Embankment Slope Protection Stabilization

Project Overview

Side slope erosion has always been an issue for highway embankments. Especially during the monsoons, these slopes pose a challenge. The Larsen & Toubro-IDPI SPV, constructing its 163km long Rourkela-Sambalpur toll-way road project in Odisha faced this issue. The project is along the state highway SH-10, extending the original two lanes to four lanes. Odisha, a state on the East Coast of India is known for high intensity rains for long durations.

Initial site condition

The embankment slope lengths were as long as 16 metres with a slope gradient of 2H : 1V. Such slopes are susceptible to erosion due to rainwater run-off and progressive attrition can compromise the stability of the vital earth structure.
