ABSTRACT:
A starting material is stretched longitudinally to produce a geogrid. The starting material has pronounced ribs on each face, merging into sloping sides. Between the ribs, there are holes on a square grid. The mean thickness of the longitudinal elements is substantially greater than the mean thickness of the interconnecting elements, and the cross-sectional area of the longitudinal elements is at least 2.5 times the transverse cross-sectional area of the interconnecting elements. The longitudinal elements are stretched out into continuous oriented strands. The centers of the junctions reduce in thickness by at least 10% but substantially less than the percentage reduction at the thinnest part of the strand.
