Mabatirwo akabatanidzwa emugero usingapindi mvura bhodhi ndiyo nzira yakakosha yekuvaka. Kazhinji, nzira yekupisa welding inoshandiswa. Iyo yepamusoro yePE firimu inopisa kuti inyungudutse pamusoro, uye yozobatanidzwa mumuviri mumwe nekumanikidza. Pamipendero yezvisungo zveakagadzika tunnel isina mvura bhodhi Inodiwa kuti hapafanirwe kunge paine mafuta, mvura, guruva, nezvimwe pamubatanidzwa. Asati apinza, iyo PE imwe firimu pamativi maviri ejoint inofanira kugadziridzwa kuti iite kupindirana nehumwe hupamhi. Shandisa yakakosha welding muchina kuti weld mugero usingapindi mvura bhodhi, uye kongiri isingapindiki inoumbwa nekuwedzera inosimbisa isina mvura mumiriri mukongiri, inogona kuvandudza kusapinda kwemvura uye kusapinda. Iyo isingapindi mvura layer inogarotora yakanamirwa nekunze isingapindi mvura. Kune iyo composite lining, isa iyo interlayer isingapindi mvura layer. Zvishandiso zvisingapindi mvura zvinowanzo shandiswa zvisingapindi mvura mafirimu uye mabhodhi asingapinde mvura akagadzirwa nemasynthetic resin uye geotextile polymers.
