GeotecTM Flame retardant Biaxial Geogrid

GEOTECTM FR biaxial geogrids are biaxially polypropylene geogrids especially designed for containment of rock debris in tunneling and mining applications.

GEOTECTM FR geogrids are well suited for mining grating; they do not contribute significantly to the fire propagation and to the generation of smoke while burning (ISO 9705), being stabilized with fire retardant additive; they are clearly visible, being white in color, when used underground environment; they are strong, durable and easy to install.

 

[Typical applications]

 

Mining grating - indoor grid - rock protection grid for tunneling - indoor fence.
