Tlhaloso ea Lihlahisoa
Boto e kopaneng e sa keneleng metsi le e ntshang metsi e entsoe ka lera le le leng kapa a mabeli a geotextile e sa lohiloeng le lera la motheo oa geonet oa maiketsetso oa mahlakore a mararo. E na le ts'ebetso e felletseng ea "ts'ireletso ea ho sefa-ho hema-ho hema-ho thiba moea ka morao". Sebopeho sena se etsa hore boto e kopaneng e sa keneleng metsi le e ntshang metsi e sebetse hantle mererong e fapaneng, haholo-holo mererong ea ho ntsha metsi joalo ka literene, litsela tse kholo, lithanele, merero ea masepala, matamo a metsi le tšireletso ea matsoapo.
Maemo a Kopo
Liboto tse kopaneng tse sa keneleng metsi le tse ntšang metsi li sebelisoa haholo masimong a fapaneng a boenjiniere:
1. Literene, litsela tse kholo, lithanele, merero ea masepala: e sebelisetsoang ho ntsha metsi le ho sireletsa.
2. Tšireletso ea letamo le letsoapong: e sebelisetsoa ho matlafatsa le ho sireletsa.
3. Kalafo e bonolo ea motheo, matlafatso ea roadbed, le tšireletso ea letsoapong: ntlafatsa botsitso le phello ea ho ntša metsi.
4. Matlafatso ea likhokahano tsa borokho, tšireletso ea letsoapong la lebōpo: thibela khoholeho ea mobu le ho sireletsa meaho.
5. Ho lema marulelo a karache ka tlas'a lefatše le ho lema marulelo: ho sebelisoa bakeng sa ho thibela metsi le ho ntša metsi, ho sireletsa sebopeho.
Litšobotsi tsa Tshebetso
1. Ho ntsha metsi ka matla: ho lekana le phello ea ho ntsha metsi ha ho ntsha metsi ka lehlohlojane le teteaneng la mithara e le 'ngoe.
2. Matla a ho tsitlella a phahameng: a khona ho mamella mojaro o phahameng oa khatello, joalo ka mojaro oa khatello oa 3000Ka.
3. Ho hanyetsa mafome, ho hanyetsa asiti le alkali: bophelo bo bolelele ba tšebeletso.
4. Kaho e bonolo: khutsufatsa nako ea kaho le ho fokotsa litšenyehelo.
5. Ho tenyetseha ho hotle: ho kgona ho kobeha kaho le ho ikamahanya le maemo a fapaneng a rarahaneng.
