SF 20
SOIL REINFORCEMENT GEOGRID
Biaxial Geogrid
The Strength is in both directions
SF 20 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.
