12.5 FT. X 328 TRIAX TX GEOGRID POLYPROPYLENE TYPE 2

Description

The geogrid is manufactured from a punched polypropylene sheet, which is then oriented in three substantially equilateral directions so that the resulting ribs shall have a high degree of molecular orientation, which continues at least in part through the mass of the integral node.
