Tensar Webinar - Stabilised Gravel Rafts: Mitigating Seismic Liquefaction Damage

Soil liquefaction is a critical geotechnical hazard that occurs during seismic events, when loose, saturated sands temporarily lose their strength and behave like a fluid. This can result in severe ground deformation and significant damage to buildings and infrastructure. 

To mitigate these risks, shallow foundation solutions using mechanically stabilised gravel rafts have been widely adopted. These systems enhance bearing capacity and reduce differential settlement improving structural resilience and helping to protect human life in earthquake-prone regions.

This session highlights how mechanically stabilised gravel rafts can improve shallow foundation performance in earthquake-prone regions.

• The fundamentals of soil liquefaction, including its causes and geotechnical risks
• Effective approaches to mitigate liquefaction in seismic conditions
• Key design and construction principles for geogrid-stabilised gravel rafts
• Tensar case studies demonstrating real project applications and outcomes
