SYNTEEN SF11
BASE COURSE REINFORCEMENT
SUBGRADE IMPROVEMENT BIAXIAL GEOGRID
SF11 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 polymer coating. SF Geogrids are inert to biological degradation and are resistant to naturally encountered chemicals, alkalis and acids.

SF11 INCREASES THE SERVICE LIFE OF PAVEMENT STRUCTURES BY IMPROVING:
CONFINEMENT OF BASE COURSE
1. Prevents lateral spreading of the base or sub-base aggregate
2. Allows for shear interaction to develop between the aggregate and the geogrid
INCREASED TENSILE STRENGTH OF AGGREGATE
1. SF11 geogrid will reduce applied vertical pressure of heavy loads at depth of aggregate by spreading loads over a wider area.
