Mbali
1. Mphamvu yayikulu: pansi pa zofunikira zomwezo za kulemera kwa gramu, mphamvu yokoka ya ma geotextiles atali a silika opindidwa ndi singano mbali zonse ndi yayikulu kuposa ya ma nonwoven ena opindidwa ndi singano, ndipo ili ndi mphamvu yokoka kwambiri.
2. Kugwira bwino ntchito kwa creep: Geotextile iyi ili ndi ntchito yabwino ya creep, imatha kusunga ntchito yokhazikika ikagwiritsidwa ntchito kwa nthawi yayitali, ndipo sikophweka kusintha.
3. Kukana dzimbiri mwamphamvu, kukana ukalamba komanso kukana kutentha: geotextile yopangidwa ndi silika wautali wopindidwa ndi singano yopanda ulusi imakhala ndi kukana dzimbiri bwino, kukana ukalamba komanso kukana kutentha, ndipo ingagwiritsidwe ntchito kwa nthawi yayitali m'malo ovuta popanda kuwonongeka.
4. Kugwira ntchito bwino kwambiri pakusamalira madzi: ma pores ake omangidwa amatha kuyendetsedwa bwino kuti akwaniritse kulowa kwa madzi, komwe kuli koyenera mapulojekiti omwe amafunika kuwongolera kuyenda kwa madzi.
5. Kuteteza chilengedwe komanso kulimba, kotsika mtengo komanso kogwira mtima: poyerekeza ndi zipangizo zachikhalidwe, geotextile yayitali yokhala ndi silika wopindidwa ndi silika ndi yotetezeka kwambiri ku chilengedwe, imatha kubwezeretsedwanso ndikugwiritsidwanso ntchito, imachepetsa kuvutika kwa chilengedwe, komanso imakhala yolimba kwambiri, kuwonetsedwa kwa nthawi yayitali kumathabe kukhalabe ndi magwiridwe antchito okhazikika, kuchepetsa kwambiri ndalama zokonzera.
6. Kapangidwe kosavuta: kapangidwe kosavuta, sikufuna ukadaulo ndi zida zovuta, kusunga anthu ndi zinthu zina, koyenera mapulojekiti mwachangu.
Kugwiritsa ntchito
Amagwiritsidwa ntchito m'dera la msewu waukulu, sitima, damu, gombe la m'mphepete mwa nyanja pothandizira kupondereza, kusefa, kulekanitsa ndi kukhetsa madzi, makamaka m'madambo amchere ndi m'malo osungira zinyalala. Makamaka posefa, kulimbitsa ndi kulekanitsa.
