Ibhodi yePlastiki yoMbhobho
Ibhodi yeplastiki yokukhupha amanzi yenziwe nge-polystyrene (HIPS) okanye i-polyethylene (i-HDPE) njengezinto eziluhlaza. Kwinkqubo yokuvelisa, iphepha leplastiki ligximfizwe ukwenza iqonga elingenanto. Ngale ndlela, ibhodi yokukhupha amanzi iyenziwa.
Ikwabizwa ngokuba yi-concave-convex drainage plate, ipleyiti yokukhusela i-drainage, i-garage roof drainage plate, i-drainage plate, njl. Ukuqinisekisa ukuba amanzi angaphezulu kuphahla lwegaraji anokukhutshwa emva kokuzaliswa ngasemva. Ingasetyenziselwa ukukhupha amanzi kwitonela.
