1. Kuyika kwa geotextile. Ogwira ntchito yomanga ayenera kutsatira mfundo ya "kuchokera pamwamba mpaka pansi" malinga ndi geotextile panthawi yoyika. Malinga ofukula kupatuka kwa olamulira, si koyenera kusiya kugwirizana kwa chapakati longitudinal mng'alu. Munthawi yomanga iyi, ogwira ntchito yomanga ayenera kulabadira chilango cha maziko a chithandizo kuti malo omangidwawo akhale athyathyathya komanso aukhondo. Pofuna kupewa malo osagwirizana pamtunda wapansi ndikukonza ming'alu pamtunda, m'pofunikanso kufunsa ndi kupeza kulimba kwa nthaka. Panthawi yoyika, ogwira ntchito yomanga sayenera kuvala nsapato zolimba kwambiri kapena kukhala ndi misomali pansi. Chisamaliro chiyenera kutengedwa posankha chinthu chofukiza kuti chiteteze bwino zinthuzo. Pofuna kupewa kuwonongeka kwa mphepo pa nembanemba, matumba a mchenga kapena zinthu zina zofewa ziyenera kugwiritsidwa ntchito potaya kwambiri ndi chilango cha zipangizo zonse panthawi yoyika, kuti akhazikitse maziko abwino oyika zipangizo.
2. Geotextile kusoka ndi kuwotcherera. Pogwirizanitsa zinthu, ogwira ntchito yomangayo ayenera kutsatira mfundo yoyankhira kuti atsimikizire kuti kugwirizanako kuli kofanana. Choyamba, geotextile yapansi idzasokedwera chilango, ndiye kuti geotextile yapakati idzamangirizidwa, ndiyeno pamwamba pa geotextile idzasokedwera chilango. Asanayambe kumanga kuwotcherera, akatswiri omangamanga ayenera kuyang'ana njira yowotcherera kuti adziwe kutentha ndi kuwongolera liwiro la makina owotcherera pa tsiku lomanga, ndikupanga kusintha koyenera malinga ndi momwe zimakhalira. Pamene kutentha kuli pakati pa 5 ndi 35 ℃, kuwotcherera ndikoyenera. Ngati kutentha pa tsiku lomanga sikuli mkati mwa izi, akatswiri a zomangamanga ayenera kumaliza ntchitoyo ndi kufunafuna kuwongolera koyenera. Pamaso kuwotcherera, zonyansa pa kuwotcherera pamwamba ayenera kutsukidwa kuonetsetsa ukhondo wa kuwotcherera pamwamba. Chinyezi chomwe chili pamtunda wowotcherera chimatha kuyanika ndi chowuzira chamagetsi. Pamwamba pa kuwotcherera akhoza kukhala youma. Polumikizana ndi ma geotextiles angapo, ming'alu yolumikizana iyenera kugwedezeka ndi kupitilira 100cm, ndipo zolumikizira zowotcherera ziyenera kukhala zooneka ngati T. Zolumikizira zowotcherera sizingakhazikitsidwe ngati mawonekedwe opingasa. Pambuyo pomanga kuwotcherera kumalizidwa, kuwongolera khalidwe la kugwirizana kudzachitidwa pofuna kupewa kuwotcherera kutayikira, kupindika ndi mavuto ena. Pa kuwotcherera ndi mkati mwa maola awiri mutatha kuwotcherera, kuwotcherera pamwamba sikudzakhala pansi pa kupsinjika kwamphamvu kuti mupewe kuwonongeka kwa malo owotcherera. Ngati mavuto aakulu kuwotcherera amapezeka mu kuwotcherera khalidwe anayendera, monga kuwotcherera chopanda, kuwotcherera kuwonjezera, kuwotcherera ogwira ntchito ayenera kudula malo kuwotcherera, mawonekedwe mawonekedwe pambuyo kuwotcherera ndi zina latsopano kuwotcherera chilango. Ngati pali kutayikira m'malo owotcherera, ogwira ntchito kuwotcherera ayenera kugwiritsa ntchito mfuti yapadera yowotcherera kuti akonze zowotcherera ndikutaya chindapusa. Akamisiri owotcherera akawotcherera geotextile, amayenera kuwotcherera mosamalitsa malinga ndi zofunikira za kapangidwe kake komanso momwe amawotcherera kuti atsimikizire kuti mtundu wa kuwotcherera ukukwaniritsa miyezo yoyenera. Geotextile iyenera kuwonetsa kwathunthu mphepo yotsutsa-seepage.
3. Geotextile suture. Pindani kumtunda kwa geotextile ndi geotextile yapakati kumbali zonse ziwiri, kenako yosalala, lamba, gwirizanitsani ndi kusoka geotextile yapansi. Makina osokera pamanja amagwiritsidwa ntchito kusoka ma geotextiles, ndipo mtunda woyenda molunjika umayendetsedwa mkati mwa 6mm. Pamalo olumikizana ndi omasuka pang'ono komanso osalala, ndipo geotextile ndi geotextile ali pamavuto olumikizana. Miyezo yoluka ya kumtunda kwa geotextile ndi yofanana ndi ya m'munsi mwa geotextile. Nthawi zambiri, malinga ngati njira zomwe zili pamwambazi zikutsatiridwa, pasakhale mavuto. Komabe, tiyenera kusamala pakukonza mphamvu ya geotextile m'tsogolomu.
