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.

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:

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.
