Fujairah Freeway

Check infrastructure performance from your desk…

Fujairah Freeway

The Dubai-Fujairah Freeway is a 45km highway across the UAE, including a section through the rugged Hajar Mountains with enormous volumes of cut and fill. Some sections are supported on record-breaking 70m high reinforced soil wall but, as so often happens after successful delivery, the monitoring stopped soon after construction. Tensar wanted to check how their record-breaking walls were performing 10 years after construction but the only way appeared to be costly in-situ surveys with multiple site visits. 

InSAR analysis was performed on satellite data of the area over a four-year retrospective period. The satellite data was combined with the in-situ monitoring data collected during and after construction, demonstrating the excellent wall performance over the last 10 years. Performance trends were immediately obtainable without having to wait months to accumulate monitoring data, and the data was collected in a safe and non-disruptive manner without needing to visit the site.

Highlights 


  • Four-year historical displacement measurement of reinforced soil wall using InSAR.

  • A fraction of the cost of in-situ surveys. 

  • Excellent performance of this record-breaking reinforced soil wall was confirmed.
