HIGH-STRENGTH GEOSYNTHETIC SOLUTIONS stabilization of areas at risk of collapse

Underground Cavities: A Major Risk to Infrastructure Underground cavities represent a frequently invisible threat to infrastructure. Whether of natural origin (dissolution of limestone or gypsum formations) or anthropogenic origin (linked to former mining operations or quarries), they weaken the ground and may lead to progressive settlement or localized ground collapses, known as sinkholes. Roads, working platforms, utility networks, and structures can therefore suffer severe damage, with significant consequences in terms of safety and repair costs. To mitigate these risks and ensure the long-term...

REINFORCEMENT GEOSYNTHETICS FOR CAVITY TREATMENT ■ OPERATING PRINCIPLE ■ Cavity bridging and immediate load transfer: the geosynthetic acts as a structural membrane capable of redistributing stresses in the event of cavity opening. ■ Controlled and predictable deformation, compliant with current design methods and standards, ensuring the safety and durability of the structure. ■ Tailored design: geosynthetic sizing based on the potential cavity diameter, applied loads, backfill thickness and characteristics, as well as long-term settlement criteria. ■ Mobilization of the geosynthetic tensile...
