ʻO Uniaxial plastic geogrid, i hana ʻia me ka polymer molecular kiʻekiʻe o ka polypropylene, e hoʻokuʻu ʻia i loko o ka pepa a laila kuʻi ʻia i loko o ke ʻano mesh maʻamau a hoʻopaʻa hope ʻia i ka ʻaoʻao transverse. Hiki i kēia hana ke hōʻoia i ka paʻa pono o ka geogrid. Kūleʻa nui ka mea PP a pale i ka elongation ke kau ʻia i nā ukana kaumaha no ka manawa lōʻihi.
