SF 350
SOIL REINFORCEMENT GEOGRID
Uniaxial Geogrid
The Strength is in the length direction
SF 350 is composed of high molecular weight, high tenacity multifilament polyester yarns that are woven into a stable network placed under tension. The high strength polyester yarns are coated with a PVC material. SF SERIES Geogrids are inert to biological degradation and are resistant to naturally encountered chemicals, alkalis and acids. SF SERIES Geogrids are typically used for soil reinforcement applications such as retaining walls, steepened slopes, embankments, sub-grade stabilization, and embankments over soft soils and waste containment applications.
