Non-woven geotextile Geoter FN

compositepolyesterPVA

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. • 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) • Reinforcing geosynthetic made of high-tenacity polyester by the combination of a non-woven geotextile (separation and filtration function) and high-strength polymer cables (reinforcement function). • Roll width : 5.30 m • Roll length : 70 or 100 m • Tensile strength : up to 2,000 kN/m with low elongation depending on the product in the range
