The client proposed building an access road to the villas in the hilly terrains of the Nilgiris in Coonoor, Tamil Nadu. The challenges included difficulty for the movement of heavy construction machinery on the hilly terrain due to deep ruts. Also, heavy traffic movement was affected due to improper and insufficient drainage, especially during the monsoons. Therefore, there was a need to have a definitive solution for subgrade improvement.

Strata’s team of geotechnical experts proposed the design using StrataWeb® for the strengthening of the flexible pavement. Introducing StrataWeb® SW 356-150 geocells in a granular base or subbase improves pavement longevity and economizes the overall crust thickness.
 

StrataWeb® was selected as an innovative solution that saved approx. 15% of the cost, helped faster execution of work with an excellent inbuilt drainage feature for strengthening flexible pavement in the hilly terrain.
