I-geogrid yeplastiki luhlobo olutsha lwemathiriyeli yepolymer eveliswe kuluntu lwanamhlanje. Emva kokwelulwa kolwalathiso lwe-bidirectional, izinto eziphathekayo zinobude obufanayo kunye nokuqina okuguquguqukayo, i-ductility efanelekileyo, ukumelana nokudinwa okuphezulu kunye nokusebenza kakuhle. Ekugcinweni koluhlu olukhuselayo, kuyimfuneko ukuba ukhusele ngokungqongqo kwaye ukhethe izinto ezinobunzima obunzima kunye nobukhulu obufanayo. Ngokumalunga nokucoca i-sand cushion medium and coarse sand, umxholo wodaka ungaphantsi kwe-5%, injongo kukwenza umjelo wokuhambisa amanzi.
I-geogrid yeplastiki yenziwe ngemolekyuli ephezulu yokuxova i-polymer, ipleyiti yokwenza, kunye nokwelula ubude kunye nasecaleni emva kokubetha. Izinto eziphathekayo zinamandla amakhulu okuxinana kwiindlela zelongitudinal kunye nezinqamlezayo, kwaye isakhiwo sinokubonelela ngomthwalo osebenzayo kunye nenkqubo yokudibanisa ekhululekileyo emhlabeni, kwaye isetyenziselwa ukuqinisa isiseko somthwalo omkhulu.
Ngenxa yokuba iigeogrids zeplastiki zichatshazelwa ziimeko zokusingqongileyo, ubunjineli obuphantsi komhlaba kufuneka buqwalasele nzulu imiphumo eyingozi yamanzi aphantsi komhlaba, kwaye basebenzise iindlela ezisebenzayo zokuthintela ukugqunywa kwamanzi aphantsi komhlaba, ukudleka kunye nomonakalo. Xa ixesha lemvula lifika, ukungalingani kwendlela okanye ukuqokelelwa kwamanzi kufuneka kulungiswe kwaye kupheliswe ngexesha. Uninzi lwemisebenzi yekhonkrithi ityhileke emoyeni, ayintywiliselwa emanzini.
I-geogrid yeplastiki eneendlela ezimbini isetyenziswa njengomaleko kunye nomqamelo wesanti okanye umaleko wokuzalisa. Olu luhlu lunobunzima obuhlukeneyo ukusuka kwi-roadbed kunye nesiseko okanye isiseko esithambileyo. Yisiseko se-raft esiguquguqukayo se-embankment kunye nomjelo wokuhambisa amanzi wesiseko kunye nomhlaba othambileyo. Amanzi angaphezulu angalahleka ngokungena kwegridi, ukuxutywa kwezixhobo ezahlukeneyo, ngoko ke, i-deformation yesiseko ifana, kwaye ukuhlaliswa kokwahlukana kuncinci.
