Solutions for cavities

Product catalog summary

Introduction
Underground cavities pose significant risks to infrastructure, potentially leading to ground collapses and sinkholes. These can result in severe damage to roads, utility networks, and structures, with high safety and repair costs.

Geosynthetic Solutions
The Geoter® and NoteX® ranges offer high-strength geosynthetic solutions for reinforcing areas at risk of collapse. These solutions help distribute loads and create a bridging effect over weakened areas.

Product Features

High-strength reinforcement geocomposite and geogrid.
Load transfer and cavity bridging capabilities.
Controlled deformation compliant with design standards.
Tailored design based on cavity size and load conditions.
Maintenance of infrastructure functionality despite underlying void changes.

Advantages

Long-term protection with reliable technology.
Suitable for large-diameter cavities and chemically aggressive environments.
Cost-effective compared to traditional solutions.
Fast installation with minimal disruption.
Proven compliance with standards for reliability and safety.

Applications

Karst areas.
Underground galleries and cellars.
Anthropogenic cavities like mining galleries.
Areas beneath geomembrane installations.
Collapse-prone regions.

Company Strengths

Agile organization for responsiveness and cost control.
Comprehensive technical support and assistance.
100% French manufacturing ensuring quality and traceability.
Recognized expertise in geosynthetic solutions.
Dedicated technical contacts for project follow-up.

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...
