Boto e Ntle ea Metsi a Marulelo a Serapa sa HDPE Dimple Membrane Membrane Composite Drainage Boto e sa keneleng Metsi e nang le Mokelikeli o le Mong oa Lehlakore la Dimple
Boto ea drainage e kopantsoeng ke mofuta oa thepa ea moaho e sebelisoang kahong ho tsamaisa metsi le ho thibela mongobo ho bokellana holim'a metheo ea meaho kapa marulelong. Hangata e na le "high-density polyethylene" (HDPE) ea mantlha e kentsoeng lipakeng tsa likarolo tse peli tsa "geotextile filter".
Sepheo sa boto ea drainage e kopantsoeng ke ho fana ka mocha oa hore metsi a phalle ho tloha mohahong le ho thibela metsi ho kopana le ho baka tšenyo. Likarolo tsa geotextile mahlakoreng ka bobeli a HDPE core li sefa likaroloana tse ntle le ho thibela ho koaloa ha boto ea drainage, ho lumella ho phalla ha metsi hantle.
Liboto tsa drainage tse kopantsoeng hangata li sebelisoa lits'ebetsong moo mobu o sa tsitsang kapa o nang le drainage e mpe, joalo ka marulelong a matala, maboteng a plaza le maboteng a mokatong o ka tlase. Li boetse li sebelisoa ka tloaelo mererong ea boenjiniere ba sechaba le merero ea meralo ea motheo, joalo ka mabota a litsela le literene, ho thibela ho bokellana ha metsi le khoholeho ea mobu.
Ka kakaretso, liboto tse kopaneng tsa drainage li ka fana ka litharollo tse sebetsang hantle le tse sebetsang hantle bakeng sa mathata a taolo ea metsi mererong ea kaho le meaho.
