Netiweki yolumikizira madzi ya geotechnical Composite Yopangidwa ndi geotextile yapadera ya geonet yokhala ndi mbali ziwiri yolumikizidwa. Imaphatikiza geotextile (yotsutsana ndi kusefera) ndi geonet (yogwirizana ndi kutsekereza madzi) kuti ipereke zotsatira zonse za "chitetezo cha kutsekereza madzi". Netiweki yolumikizira madzi ya magawo atatu Ndi chinthu chatsopano chopangidwa ndi geosynthetic. Kapangidwe kake ndi geonet core yokhala ndi mbali zitatu yokhala ndi geotextile yobowoledwa ndi singano yolumikizidwa mbali zonse ziwiri. Geonet core yokhala ndi mbali zitatu imaphatikizapo nthiti imodzi yolimba yoyima, ndi nthiti imodzi yopendekera pamwamba ndi pansi. Imatha kutulutsa madzi apansi panthaka mwachangu kuchokera mumsewu, komanso ili ndi njira yosungira madzi, yomwe ingatseke madzi a capillary pansi pa katundu wambiri.
Pambuyo poti msewu wayamba kukalamba ndi ming'alu, madzi ambiri amvula adzalowa m'gawolo. Pankhaniyi, netiweki yamadzimadzi ya Composite yokhala ndi magawo atatu imayikidwa mwachindunji pansi pa msewu m'malo mwa maziko otulutsira madzi. Netiweki yamadzimadzi yamitundu itatu ingagwiritsidwe ntchito madzi akalowa m'maziko / Gawo la pansi limasonkhanitsidwa kaye. Komanso filimu ikhoza kukulungidwa kumapeto kwa ukonde wamadzimadzi wamitundu itatu kuti ateteze chinyezi kuti chisalowe m'maziko. Pa njira zolimba za misewu, kasinthidwe kameneka kamalola kuti madzi azituluka Cd apamwamba kuti apange msewu. Ubwino wina wa kapangidwe kameneka ndikuti kamalola konkire kuti isungunuke mofanana (kafukufuku wokhudza kuchuluka kwa ubwino uwu ukupitilira). Kaya ndi misewu yolimba kapena njira zosinthasintha za misewu, kapangidwe kameneka kangathe kutalikitsa moyo wa misewu.
Ukonde wophatikizana wa geotechnical drainage uli ndi geotextile yobowoledwa ndi singano mbali zonse ziwiri ndi pakati pa maukonde atatu pakati. Kudzera mu makina otsekereza kutentha, geotextile ndi pakati pa maukonde atatu zimagwirizanitsidwa pamodzi kuti apange netiweki ya maukonde atatu yokhala ndi kapangidwe ka maukonde atatu. Imatha kusewera ntchito yosefa ndi kutulutsa madzi. Ukonde wophatikizana wa maukonde atatu uli ndi gawo la geomembrane yophatikizika ndi gawo la geotextile ndi gawo la pakati pa maukonde atatu; Kudzera mu makina otsekereza kutentha, geomembrane yophatikizika ya geotextile ndi pakati pa maukonde atatu zimagwirizanitsidwa pamodzi kuti apange netiweki ya maukonde atatu osalowa madzi ndi kapangidwe ka maukonde, yomwe imagwiritsidwa ntchito makamaka pochotsa madzi, ndipo geomembrane yophatikizika imagwira ntchito yophatikizika kwambiri.
Ukonde wothira madzi wopangidwa ndi magawo atatu ndi chinthu chatsopano chopangidwa ndi geosynthetic. Kapangidwe kake ndi pakati pa geonet wa magawo atatu wokhala ndi geotextile yosalukidwa yokhala ndi singano yobowoledwa mbali zonse ziwiri. Pakati pa geonet wa magawo atatu pali nthiti imodzi yokhuthala yoyima, ndi nthiti imodzi yopendekera pamwamba ndi pansi. Imatha kutulutsa madzi apansi panthaka mwachangu kuchokera mumsewu, komanso ili ndi njira yosungira ma pore, yomwe ingatseke madzi a capillary pansi pa katundu wambiri. Nthawi yomweyo, ingathenso kuchita gawo lodzipatula komanso lolimbitsa maziko. Chinthu chatsopano chopangidwa ndi geosynthetic. Ukonde wothira madzi wopangidwa ndi magawo atatu umapangidwa ndi geotextile yapadera ya magawo atatu yokhala ndi mbali ziwiri. Imaphatikiza geotextile (anti-filtration action) ndi geonet (drainage and protection action) kuti ipereke zotsatira zonse za "anti-filtration drainage protection". Kapangidwe kapadera ka magawo atatu ka pakati pa ma ponet wothira madzi wopangidwa ndi magawo atatu kangathe kupirira katundu wopanikizika kwambiri panthawi yonse yogwiritsira ntchito, ndipo imatha kusunga makulidwe ambiri, kupereka ma hydraulic conductivity abwino.
