The section of the National Highway (NH-8) connecting Surat to Bharuch needed a site solution that would create additional roadway access to the prevailing high density to ease the traffic on the National Highway. The National Highway Authority decided to construct three flyovers and one vehicular underpass.

The biggest challenge was that each location faced unique problems ranging from erratic soil conditions to seepage water. The onsite soil investigation report, which was carried out to assess the soil’s bearing capacity, indicated the soil was weak, which could lead to excessive settlement of the structures.

A reinforced soil wall system was the most preferred solution for this project based on the prevailing soil conditions. StrataGrid™ and StrataBlock™ units were used for the construction of the reinforced soil wall due to their proven performance and easy installation procedure.

Strata completed the structures on time after tackling complex challenges and provided the client with superior quality service, which was well appreciated by the client. This level of efficiency enabled the client to start traffic on the structures on time.
