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 163 km long Rourkela-Sambalpur tollway road project in Odisha, faced this issue.

The StrataWeb® innovative solution for side-slope protection is cost-effective, technically sound, long-lasting and eco-friendly. The technically advanced solution leaves a low carbon footprint and lush greenery along the highway embankment slope, besides protecting the slopes against erosion.

StrataWeb® prevents erosion along the slope by providing a stable layer of confined material over the surface. StrataWeb® SW 712-75, when infilled with soil, acts effectively as a barrier to virtually eliminate erosion along the slope surface. It provides a stable layer of confined material over the slope surface. The confined layer fosters vegetation growth to provide a green surface. Roots of the vegetation further prevent erosion.

The use of StrataWeb® provided a beautiful, green and environment-friendly highway and saved up to 50% of the cost compared to the convention solution of stone pitching.
