Udindo wa geogrids polimbana ndi maziko ofooka umawonekera makamaka m'zigawo ziwiri: choyamba, kupititsa patsogolo mphamvu yonyamula maziko, kuchepetsa kukhazikika, ndi kuonjezera kukhazikika kwa maziko; Chachiŵiri ndicho kukulitsa kukhulupirika ndi kupitiriza kwa nthaka, kulamulira bwino kukhazikika kosagwirizana.
Mapangidwe a mauna a geogrid ali ndi ntchito yolimbikitsa yomwe imawonetsedwa ndi mphamvu yolumikizirana ndi mphamvu yolowera pakati pa mauna a geogrid ndi zinthu zodzaza. Pansi pa katundu woyima, ma geogrids amatulutsa kupsinjika kwamphamvu kwinaku akugwiritsanso ntchito mphamvu yoletsa nthaka, zomwe zimapangitsa kuti pakhale kumeta ubweya wambiri komanso kupunduka kwa dothi lophatikizana. Nthawi yomweyo, geogrid yotanuka kwambiri imatulutsa kupsinjika koyima pambuyo pokakamizidwa, kutsitsa katundu wina. Kuonjezera apo, kukhazikika kwa nthaka pansi pa katundu woyima kumayambitsa kukweza ndi kusuntha kwa nthaka kumbali zonse ziwiri, zomwe zimapangitsa kuti pakhale kupanikizika kwa geogrid ndikulepheretsa kukweza kapena kusuntha kwa nthaka.

Maziko akakhala ndi vuto lakumeta ubweya, ma geogrids amalepheretsa mawonekedwe olephera ndipo motero amakulitsa mphamvu yonyamula maziko. Kuthekera kwa geogrid reinforced composite maziko atha kuwonetsedwa ndi njira yosavuta:
Pu=CNC+2TSinθ/B+βTNɡ/R
Kugwirizana kwa C-dothi mu chilinganizo;
NC Foundation yokhala ndi mphamvu
T-Tensile mphamvu ya geogrid
θ - mbali yolowera pakati pa maziko a maziko ndi geogrid
B - Pansi m'lifupi mwa maziko
β - mawonekedwe a maziko;
N ɡ - Maziko ophatikizika okhala ndi mphamvu
R-Kusinthika kofanana kwa maziko
Mawu awiri omaliza mu fomula akuyimira kuchuluka kwa kunyamulira kwa maziko chifukwa choyika ma geogrids.

Chophatikizika chopangidwa ndi geogrid ndi zinthu zodzaza zimakhala ndi kuuma kosiyana ndi mpanda ndi maziko ofewa otsika, ndipo zimakhala ndi mphamvu zometa ubweya ndi kukhulupirika. Gulu lodzaza ndi geogrid likufanana ndi nsanja yotengera katundu, yomwe imasamutsa katundu wa mpanda wokha ku maziko ofewa otsika, ndikupanga kusinthika kwa yunifolomu ya maziko. Makamaka gawo lakuya la simenti yosakaniza mulu wa mankhwala, mphamvu yobereka pakati pa milu imasiyanasiyana, ndipo kukhazikitsidwa kwa magawo osinthika kumapangitsa kuti gulu lirilonse lizigwira ntchito palokha, komanso palinso kusamvana pakati pa midzi. Pansi pa njira yochizira iyi, nsanja yosinthira katundu yopangidwa ndi ma geogrids ndi zodzaza zimagwira ntchito yofunika kwambiri pakuwongolera kukhazikika kosagwirizana.
