Pakakhala mvula yambiri, mawonekedwe achitetezo otsetsereka a geotextile amatha kukhala ndi chitetezo. M'madera omwe geotextile sichikuphimbidwa, tinthu tating'onoting'ono timabalalika ndikuwuluka, ndikupanga maenje ena; M'dera lomwe limakutidwa ndi geotextile, madontho amvula amagunda pa geotextile, kufalitsa kukanikiza ndikuchepetsa kwambiri mphamvu ya nthaka yotsetsereka. Pambuyo pakukokoloka kwa petal, mphamvu yolowera m'thupi lachifumu imachepa pang'onopang'ono, ndipo madzi otsetsereka amapangidwa. Kuthamanga kumapangidwa pakati pa geotextiles, ndipo kuthamanga kumamwazikana kudzera mu geotextile, kuchititsa madzi amvula kuyenderera mu laminar state. Chifukwa cha zotsatira za geotextiles, ma grooves opangidwa ndi kuthamanga ndizovuta kulumikiza, ndi ma grooves ochepa komanso kukula kwapang'onopang'ono kwa grooves. Kukokoloka kwa ma grooves abwino kumakhala kosakhazikika pang'ono komanso kovuta kupanga. Kukokoloka kwa nthaka kumachepa kwambiri poyerekeza ndi malo otsetsereka opanda kanthu, ndi tinthu tating'onoting'ono tadothi tating'onoting'ono tating'onoting'ono ta geotextile ndi kutsekeka kwa mitsinje ndi maenje ena kumtunda.

Pakakhala mvula yambiri, nyumba zokwezeka za geotextile zimatha kuteteza malo otsetsereka, ndipo zonse, geotextile imatha kuphimba nyumba zokwezeka. Mvula ikagwa pa geotextile, imatha kuteteza bwino zomwe zidakwezedwa ndikuchepetsa kukhudzidwa kwawo. Kumayambiriro kwa mvula, malo otsetsereka akutali amadzimadzi amamwa madzi ochepa; Mvula ikadzagwa, malo otsetserekawo amakoka madzi ambiri. Pambuyo pakukokoloka, mphamvu yolowera m'nthaka imachepa pang'onopang'ono, ndipo madzi otsetsereka amapangidwa. Kuthamanga kumapangidwa pakati pa ma geotextiles, ndipo kutuluka kwapangidwe kokwezeka kumatsekedwa, zomwe zimapangitsa kuti madzi aziyenda pang'onopang'ono. Panthawi imodzimodziyo, tinthu tating'onoting'ono timadziunjikira kumtunda kwa kapangidwe kameneka, ndipo madzi amadzimadzi amamwazikana ndi geotextile, zomwe zimapangitsa kuti madziwo aziyenda mu laminar. Chifukwa cha kukhalapo kwa mapangidwe otuluka, ma grooves omwe amapangidwa ndi kuthamanga ndi ovuta kugwirizanitsa, ndi chiwerengero chochepa cha grooves ndi kukula pang'onopang'ono. Kukokoloka kwa ma grooves abwino kwakula pang'ono ndipo sikungapangidwe.

Kukokoloka kwa nthaka kumachepa kwambiri poyerekeza ndi malo otsetsereka opanda kanthu, tinthu tating'onoting'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono, kukokoloka kwa nthaka kumachepa kwambiri poyerekeza ndi malo otsetsereka opanda kanthu. Kuteteza kwake ndikwabwino kwambiri. Chifukwa cha kutsekereza kwa zinthu zomwe zimatuluka pa dothi, chitetezo chimawonekera kwambiri kuposa zosatuluka.

Popanga ma geotextile, pofuna kupititsa patsogolo luso la zomangamanga ndikuwonetsetsa kuti ma geotextiles akuyenda bwino, mfundo zotsatirazi ziyenera kutsatiridwa. Choyamba, pewani ma geotextiles kuti asawonongeke ndi miyala. Chifukwa cha nsalu ngati chilengedwe cha geotextiles, ikayikidwa pamiyala, imadulidwa mosavuta ndi miyala yakuthwa pokhudzana ndi miyalayi, yomwe imalepheretsa kugwiritsa ntchito bwino mphamvu zawo zosefera komanso zolimba, motero kutaya mtengo wake wokhalapo. Pakumanga konkriti, ndikofunikira kuyala mchenga wabwino pansi pa geotextile kapena kuchita ntchito yoyenera yoyeretsa kuti mugwire bwino ntchito yoteteza komanso yoteteza. Kachiwiri, kulimba kwa ma geotextiles olukidwa nthawi zambiri kumakhala kolimba munjira yotalikirapo kuposa njira yodutsa, m'lifupi mwake pakati pa 4-6 metres. Ayenera kuphatikizika panthawi yomanga mtsinje, zomwe zingapangitse malo ofooka komanso kuwonongeka kwakunja. Ma geotextiles akakumana ndi zovuta, palibe njira yabwino yowasamalira bwino. Choncho, pomanga konkire, chidwi chiyenera kuperekedwa kuti pang'onopang'ono chiwonjezeke m'mphepete mwa mtsinje kuti muteteze kusweka panthawi yogona. Pomaliza, panthawi yomanga maziko, kulemera kwa katundu kuyenera kuwonjezeka pang'onopang'ono ndipo kupanikizika kumbali zonse ziyenera kusungidwa mofanana momwe zingathere. Kumbali imodzi, imatha kuteteza kuwonongeka kapena kutsetsereka kwa geotextiles, ndipo kumbali ina, ikhoza kupititsa patsogolo ntchito ya ngalande ya polojekiti yonse, kupanga maziko kukhala okhazikika.
