Pakumanga geogrid, makamaka pamene subgrade imalimbikitsidwa, kutsetsereka kotalika kwa dzenje kuyenera kukhala kopindika kwa kutembenuka kwautali wa dzenje, ndipo chodabwitsa cha madzi kudzikundikira kapena kusefukira sikuloledwa mkati mwa chipikacho.Madzi amalowetsedwa munjira yolowera m'mbali mwa phiri kapena mlatho ndi pakholvert, potulutsira ngalandeyo iyenera kukhala yolimba, ndipo ngalandeyo iyenera kupezeka, ngati kuli kofunikira, kapena zotsatira za kupopera madzi kapena madzi a tanki.
Gawo la geogrid la subgrade kapena jet lamadzi lomwe lili ndi bokosilo liyenera kugwiritsa ntchito matope omanga molingana ndi mtunda, kutalika kwa madontho amadzi, komanso kutalika ndi kutalika kwa masitepe ambiri omwe amatsimikiziridwa ndi mikhalidwe ina ya geological iyenera kutengera malo otsetsereka oyambira.Ndikofunikira kukhazikitsa terminal ndi intaneti pachipata cha maziko a zomangamanga.Maonekedwe otsetsereka otsetsereka, omwe amatha kulowa mu ngalande, apereke njira yotsetsereka, ndipo jeti lamadzi kuchokera pamphepete ndi kutsegulira ku gawo lotsetsereka la mpanda liyenera kulumikizidwa kumtunda wotsetsereka kuti mupewe madzi omwe angadutsedwe ndi ngalande yokhotakhota yamadzi, kutsekereza njira yokhotakhota yamadzi, kutsekereza njira yokhotakhota ya mapewa kapena njira yokhotakhota. Jet kuchokera pakutsegula kwa madzi osungira madzi kuti ayende kuchokera kumbali yakutali ya mpanda, ndipo kugwirizana kwa jetting groove pamtunda wa mpanda kuyenera kuperekedwa ndi pakamwa pa wokamba nkhani.Mapewa a m'mphepete mwa msewu ayenera kukonzedwa molingana ndi kapangidwe kameneko.Mapewa m'mphepete mwa msewu ayenera kulimbikitsidwa bwino.
Malo otsetsereka a geogrid ndi ngalande yotulutsira madzi potuluka ayenera kukhala ndi mawonekedwe owala ndi zotengera zina.Pofuna kupewa kulowa m'madzi ndi kukokoloka, ngalande ya ngalande iyenera kulowetsedwa ndi kulimbikitsidwa.Maonekedwe olakwika a geological ndi nthaka yofewa ikuyenera kukhala yoyenera pagawo ndi potulutsira ngalande yokhala ndi miyala yayikulu yopindika kapena dothi lotsetsereka lalitali lalitali.Njira zolimbitsira ziyenera kuchitidwa kuti madzi asasefuke ndi kukokoloka, komanso khoma la ngalande.Pamene dzenje la zinyalala likugwiritsidwa ntchito poyala, liyenera kukhala ndi tinthu tating'onoting'ono ta mwala, ndipo chinsalu chilichonse chimagwiritsa ntchito malo athyathyathya a pakamwa pake;Chilumikizano cha mwala woyalidwa ndi dongo chikhale chokwanira, ndi poyambira pakhale pothina madzi;Ngati gypsum ikugwiritsidwa ntchito pansi pa poyambira, fupa la mwala lidzasinthidwa.
