StrataGrid GG

StrataGrid is manufactured using high molecular weight (>25000 g/mol) and high tenacity polyester yarn. The yarns are precision knitted into a dimensionally stable network of apertures providing tensile reinforcement capacity in both directions. A proprietary UV stabilized saturation bitumen coating enhances chemical and mechanical properties of StrataGrid, increasing its life and enabling its usage in harsh soil conditions.

StrataGrid Strength

The bitumen coating of StrataGrid is not ordinary bitumen to begin-with. It is in fact an extremely refined and solvent extracted crystalline form of bitumen manufactured only by technologically advanced companies in the developed world. The rough texturing of PMB coating provides a better frictional characteristic as compared to the smooth finishing of PVC coating. StrataGrid has undergone rigorous Pull-out tests conducted in accredited laboratories and the results are exceeding the FHWA/BS codal provisions. Strata manufactures series of both uniaxial and biaxial geogrids.

Manufacturing

StrataGrid is manufactured in the state of the art Daheli, India. Manufacturing involves 3 phase:

Beaming
Knitting
Coating

Quality & Testing

The dilemma facing most design engineers is that all geosynthetic reinforcements are NOT created equal. The long-term performance of a geogrid is dependent on several factors such as the raw materials used, the manufacturing process adopted, the designs and the end application.
