The unidirectional拉伸plastic geogrid is a major signature technology in our company's geosynthetic category. It effectively enhances subgrade stability and load-bearing capacity, extending service life; prevents subgrade deformation and cracking caused by material loss; improves the self-supporting capability of backfill behind retaining walls, reducing soil pressure on retaining walls, saving costs, and extending service life while lowering maintenance expenses; combined with shotcrete construction methods for slope maintenance, it can save up to 30%–50% of investment and shorten the construction period by more than double; incorporating the geogrid into the subgrade and surface of highways can reduce settlement, decrease rutting, and delay the appearance of cracks by 3–9 times, potentially reducing the thickness of the structural layer by up to 36%.
