Use
Many sites are affected by the presence of natural or man-made underground cavities. These cavities can cause the soil to collapse on the surface or be destabilised, resulting in disturbances in the structures; this can even damage or destroy these structures.
GEOTER® FN the structures and helps reinforce areas exposed to a risk of cavities or localised collapse. In addition, this product can be instrumented to monitor risk developments.
In addition to its reinforcement function, GEOTER® FN plays a separation and filtration role, thanks to a non-woven geotextile, the filtration aperture of which is constant regardless of the geocomposite’s tensile strength. GEOTER® FN has an immediate tensioning feature, allowing it to instantly absorb stress and limit initial deformation during tensioning.
Benefits
- High tenacity with elongation at break of less than 11%
- Secured cavity, guaranteeing the continued operation of the structure
- The non-woven geotextile protects the cables during compaction and ensures excellent resistance to puncture
- Optimal aperture for filtration : the water flows freely and can be discharged
- Excellent permeability (>0.05 m/s)
