Preventing Premature Road Failure in Mohamed Bin Zayed City
Constructed in 2021
"The project posed challenging soil conditions with highly variable ground and challenging groundwater levels. Tensar worked closely with us, drawing insight from the extensive soil investigation data to offer shallow ground improvement solutions for individual road stretches within each zone. It is worth mentioning that Tensar geogrid solutions were prepared with careful consideration for construction feasibility and cost effectiveness".

Tensar proposed stiffening the road foundation using a mechanically stabilised layer incorporating Tensar geogrids. This stabilised layer would also mitigate differential settlement. For the higher water table areas, and areas with weak soils extending to depth, the consultant chose deep ground improvement using Controlled Modulus Columns. A Tensar mechanically stabilised subbase was incorporated to limit the differential settlement between the grouted columns within project requirements. To increase pavement life, the design was optimised by incorporating Tensar stabilisation geogrid into the base layer. This provided an increase in design life without increasing pavement thickness and cost.
- Reduced differential settlement to improve long-term pavement performance
- Increased pavement design life without additional pavement thickness
- Delivered an estimated 15% reduction in construction costs by reducing excavation and dewatering works.
- Shortened construction schedules through the elimination of excavation and backfilling
- Lowered carbon emissions through reduced material movement and haulage requirements
