Pulasitiki geogrid ndi zinthu za polima mauna okhala ndi masikweya kapena amakona anayi opangidwa ndi kutambasula. Imakhomeredwa pa pepala lopangidwa ndi polima (lomwe limapangidwa kwambiri ndi polypropylene kapena polyethylene yolimba kwambiri) kenako imayikidwa molunjika pakuwotcha. Unidirectional kutambasula grids amangopangidwa ndi kutambasula motsatira kutalika kwa pepala, pamene biaxial kutambasula grids amapangidwa ndi kupitiriza kutambasula unidirectional kutambasula gululi mu malangizo perpendicular kutalika kwake. Biaxially anatambasula pulasitiki geogrid amapangidwa polypropylene (PP) kapena polyethylene (PE) monga zopangira, extruded kudzera plasticization, kukhomerera, kutentha, longitudinal kutambasula, ndi kuwoloka kutambasula.

Kugwiritsa ntchito pulasitiki geogrid:
Geogrid ndi chida champhamvu kwambiri cha geosynthetic. Amagwiritsidwa ntchito kwambiri m'minda monga mizati, tunnel, madoko, misewu yayikulu, njanji, ndi zomangamanga.
Ntchito zake zazikulu ndi izi:
1. Kulimbikitsa bedi la msewu kumatha kugawa bwino katundu wofalikira, kukonza bata ndi kunyamula mphamvu za msewu, ndikuwonjezera moyo wake wautumiki;
2. Imatha kupirira katundu wokulirapo wosinthasintha;
3. Pewani kupotoza kwa msewu ndi kung'amba komwe kumachitika chifukwa cha kutayika kwa zida zam'misewu;
4. Kupititsa patsogolo mphamvu yonyamula katundu kumbuyo kwa khoma losungirako, kuchepetsa kupanikizika kwa nthaka pakhoma losungirako, kupulumutsa ndalama, kuwonjezera moyo wautumiki, ndi kuchepetsa ndalama zothandizira;

5. Kuphatikiza njira yomanga ya kutsitsi nangula konkire kwa otsetsereka kukonza osati kupulumutsa 30% -50% ya ndalama, komanso kufupikitsa nthawi yomanga ndi kuposa kawiri;
6. Kuonjezera ma geogrid pamphepete mwa msewu ndi pamwamba pa misewu ikuluikulu kungathe kuchepetsa kupotoza, kuchepetsa ming'alu, kuchedwetsa kuchitika kwa ming'alu ndi nthawi 3-9, ndi kuchepetsa makulidwe a zigawo zomanga ndi 36%;
7. Yoyenera dothi losiyanasiyana, popanda kufunikira kwa zitsanzo zakutali, kupulumutsa ntchito ndi nthawi;
8. Ntchito yomangayi ndi yosavuta komanso yofulumira, yomwe ingachepetse kwambiri ndalama zomanga.
