Pulasitiki geogrid ndi mtundu watsopano wa zinthu za polima zomwe zimapangidwa masiku ano. Pambuyo pa bidirectional directional kutambasula, zinthuzo zimakhala ndi mphamvu zofananira zautali komanso zopingasa zokhazikika, ductility yabwino, kukana kutopa kwambiri komanso kuchita bwino. Pokonza wosanjikiza zoteteza m`pofunika mosamalitsa zenera ndi kusankha zipangizo zolimba kapangidwe ndi yunifolomu tinthu kukula. Ponena za sing'anga yoyeretsera mchenga ndi mchenga wouma, matope amakhala osakwana 5%, cholinga chake ndikupanga ngalande.
Pulasitiki geogrid imapangidwa ndi ma polima apamwamba kwambiri a ma polima, kupanga mbale, ndi kutambasula motalika komanso mozungulira pambuyo pokhomerera. Zinthuzo zimakhala ndi mphamvu zolimba kwambiri m'magawo otalika komanso odutsa, ndipo mawonekedwewo angaperekenso katundu wogwira mtima komanso wotayirira bwino m'nthaka, ndipo amagwiritsidwa ntchito polimbikitsa maziko a katundu wamkulu.
Chifukwa ma geogrid apulasitiki amakhudzidwa ndi chilengedwe, mainjiniya apansi panthaka ayenera kuganizira mozama za kuwononga kwa madzi apansi panthaka, ndikugwiritsa ntchito njira zabwino zopewera kumeza, dzimbiri komanso kuwonongeka kwa madzi apansi panthaka. Nyengo yamvula ikafika, kusalingana kwa msewu kapena kudzikundikira kwa madzi kuyenera kukonzedwa ndikuthetsedwa munthawi yake. Ntchito zambiri za konkire zimawonekera mumlengalenga, osati kumizidwa m'madzi.
Geogrid ya pulasitiki yamitundu iwiri imagwiritsidwa ntchito ngati wosanjikiza pamodzi ndi khushoni yamchenga kapena wosanjikiza wodzaza. Chosanjikiza ichi chimakhala cholimba chosiyana ndi msewu ndi maziko kapena maziko ofewa. Ndilo maziko osunthika a raft of the embankment ndi ngalande ya madzi a maziko ndi nthaka yofewa. Madzi owonjezera amatha kutayika kupyolera mu kulowetsedwa kwa gridi, kusakanikirana kwa zipangizo zosiyanasiyana, choncho, kusinthika kwa maziko kumakhala kofanana, ndipo kukhazikika kosiyana kumakhala kochepa.
