Western dedicated freight corridor will connect Dadri to Navi Mumbai. This specific section of the project connects Rewari to Ajmer-Marwar-Iqbalgarh and lies in the states of Haryana and Rajasthan. 

The topography is hilly, and the alignment is parallel to the existing Indian Railway track. To provide for rainwater runoff and drainage, construction of an open lined drain was required for collecting storm water runoff and facilitating drainage. These drains are designed such that the geometry allows adequate flow capacity, hence less maintenance and provide uniform longitudinal gradient adequate to ensure a self-cleansing velocity. 

The conventional solution would have been riprap (stone lining). However, it posed the following challenges, such as unavailability of imported quarry material, difficulty in maintenance and in ensuring self-cleansing velocity due to surface roughness, not aesthetic enough due to poor surface finishing, costly to construct and difficult to transport quarry stone, not environment friendly and highly laborious, and high maintenance due to frequent quality issues that require frequent repairs and is not long lasting. 

To address these challenges, StrataWeb® geocells were used. The key advantages of using StrataWeb® were that it didn’t require intensive quarrying and avoided transportation of material, hence lower carbon footprint, easy construction, no formwork for concreting was required. It is maintenance-free, compared to riprap and is economical and requires less labour for construction. Geocells offer strength, flexibility and durability.
