Ma geogrid apulasitiki achitsulo ndi othandiza pothana ndi malo oundana a nthaka m'madera ozizira.
Pomanga misewu pamalo oundana m'dera lozizira, kuzizira ndi kusungunuka kwa nthaka kungabweretse zoopsa zambiri pamsewu waukulu.Madzi a m'nthaka akamaundana, amawonjezera kuchuluka kwa nthaka, zomwe zimapangitsa kuti nthaka yowumayo iwonjezereke m'mwamba, zomwe zimapangitsa kuti chisanu chiwonjezeke.
Kugwiritsira ntchito ma geogrids apulasitiki achitsulo monga gawo lolekanitsa pakati pa maziko a nthaka ndi miyala yophwanyidwa kungalepheretse silt kulowa mumsewu ndi kugubudukira panjira.Mwachitsanzo, misewu ina ikasungunuka, dothi limagwa padenga.Mukayika singano yokhomeredwa kapena anti sticking steel geogrids pakati pa miyala yamtengo wapatali, imatha kuteteza silt kupanga mitsinje.Nkofunika kumanga wabwino ambulera nyengo msewu mu kuzizira zone, nthawi zambiri popanda kuyala pansi wosanjikiza, umene umafunika wandiweyani wosweka mwala subgrade.Komabe, m'madera a permafrost nthawi zambiri mumakhala kusowa miyala ndi mchenga.Kuti muchepetse ndalama zogulira, geotextile ingagwiritsidwe ntchito kuphimba mzinda wapadziko lapansi kumanga misewu.
