Mbali
1. Mphamvu yayikulu: pansi pa kulemera kwa gilamu komweko, mphamvu yolimba ya silika wautali wopota ndi singano wa geotextiles wa singano kumbali zonse ndi yapamwamba kuposa ya ma nonwovens ena osapangana, ndipo imakhala ndi mphamvu zolimba kwambiri.
2. Kuyenda bwino kwa zokwawa: Geotextile ili ndi magwiridwe antchito abwino, imatha kukhazikika pakagwiritsidwe ntchito kwanthawi yayitali, ndipo sikophweka kupindika.
3. Kukana kwamphamvu kwa dzimbiri, kukana kukalamba ndi kukana kutentha: silika wautali wopindidwa ndi singano wosawoka wa geotextile ali ndi kukana kwa dzimbiri, kukana kukalamba komanso kukana kutentha, ndipo atha kugwiritsidwa ntchito kwa nthawi yayitali m'malo ovuta popanda kuwonongeka.
4. Kuchita bwino kwambiri posungira madzi: ma pores ake opangidwa amatha kuyendetsedwa bwino kuti akwaniritse kutsekemera kwina, komwe kuli koyenera pulojekiti yomwe ikufunika kuyendetsa madzi.
5. Chitetezo cha chilengedwe ndi cholimba, chachuma komanso chogwira ntchito: poyerekeza ndi zipangizo zamakono, silika wautali womangidwa ndi geotextile ndi wokonda zachilengedwe, akhoza kubwezeretsedwanso ndikugwiritsidwanso ntchito, kuchepetsa katundu wa chilengedwe, ndi kukhazikika kwakukulu, kuwonetseredwa kwa nthawi yaitali kungakhalebe kokhazikika. ntchito, kuchepetsa kwambiri ndalama zosamalira.
6. Kumanga kosavuta: Kumanga kosavuta, sikufuna luso lamakono ndi zipangizo, kupulumutsa anthu ogwira ntchito ndi zinthu zakuthupi, zoyenera ntchito mwamsanga.
Kugwiritsa ntchito
Amagwiritsidwa ntchito m'dera la msewu waukulu, njanji, dziwe, gombe la m'mphepete mwa nyanja pofuna kukakamiza, kusefera, kulekanitsa ndi ngalande, makamaka kugwiritsidwa ntchito m'madambo amchere ndi malo okwirira zinyalala. Makamaka mu kusefera, kulimbikitsa komanso kupatukana.
