SYNTEEN BASE COURSE REINFORCEMENT

SUBGRADE IMPROVEMENT BIAXIAL GEOGRID

SF 61 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.

SF 61 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

INCREASE TENSILE STRENGTH OF AGGREGATE

  1. SF 61 geogrid will reduce applied vertical pressure of heavy loads at depth of aggregate by spreading the load over a wider area.
