SYNTEEN BASE COURSE REINFORCEMENT
SUBGRADE IMPROVEMENT BIAXIAL GEOGRID
SF 15X 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.
SF15X INCREASES THE SERVICE LIFE OF PAVEMENT STRUCTURES BY IMPROVING:
CONFINEMENT OF BASE COURSE
- Prevents lateral spreading of the base or sub-base aggregate
- Allows for shear interaction to develop between the aggregate and the geogrid
INCREASE TENSILE STRENGTH OF AGGREGATE
- SF 15X geogrid will reduce applied vertical pressure of heavy loads at depth of aggregate by spreading the load over a wider area.
