Imisebenzi

Ngokuhlanza umgwaqo, ukuhlanza nokuhlanza, kungahlanzwa imiphetho yomgwaqo, izindonga ze-curb, ukushaya kwekhona phambili nokushaya emuva, futhi ama-spray gun aphezulu angahlanzwa izimpawu zomgwaqo, ama-billboard nezinye izisebenzi.

Uhlelo  

Kufanele isetshenziswe emisebenzini yokuhlanza enezinga eliphezulu ezikhungweni ezinkulu zedolobha, ezindleleni nasezithendeni, kanye nemisebenzi ejwayelekile yokuhlanza efana nokuhlanza nezikhungo zedolobha, ezindleleni nasezithendeni. Uma uhlelo lokuphonsa amanzi olunezinga eliphansi lukhethwa, umsebenzi wokuhlanza ongena phezulu ungaphothulwa.
