In-situ displacement monitoring of this 80m high reinforced soil wall supporting the Dubai-Fujairah Freeway was undertaken during construction 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 was used to provide several years of wall displacement data without even needing to visit the site and which showed the walls are performing extremely well.

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.
