Ukuqokwa kwekhebula kuhlinzeka ngolwazi olubalulekile mayelana nokwakhiwa kwekhebula, izinto zokufakelwa, kanye nokusetshenziswa okuhlosiwe. Ukuqonda lokhu kuqokwa kusiza ekukhetheni ikhebula elilungile lezinhlelo zokusebenza ezithile, ukuqinisekisa ukuhambisana nokusebenza.

Ingabe kukhona umehluko wezindleko phakathi kwezintambo ze-PVC, i-XLPE, ne-XLPO?

Yebo, kukhona umehluko wezindleko. I-PVC ngokuvamile iyindlela engabizi kakhulu, iyenza idume kumaphrojekthi anaka ibhajethi. I-XLPE ne-XLPO zinikeza izakhiwo ezithuthukile kodwa zivame ukubiza kakhulu, zibe nomthelela ekucatshangelweni kwesabelomali.

Ingabe ukugaywa kabusha kuyizuzisa kanjani imboni yamakhebula?

Ukugaywa kabusha konga izinsiza, kunciphisa ukumosha, futhi kusekela ukudalwa komnotho oyindilinga. Isiza ukuphatha ukulahlwa kwekhebula, ukunciphisa ukungcoliswa kwemvelo kanye nokunikeza izinzuzo zezomnotho ngokonga izindleko nokusetshenziswa kabusha kwempahla.

Yini okufanele icatshangelwe lapho ukhetha impahla yekhebula yephrojekthi?

Cabangela indawo esetshenziswayo, ukuchayeka kwamakhemikhali, izingqinamba zesabelomali, nokucatshangelwa kwemvelo. Isici ngasinye sithonya ukukhethwa kwempahla yekhebula, iqinisekisa izinhlelo zikagesi ezisebenza kahle nezithembekile eziklanyelwe izidingo ezithile zephrojekthi.
