A road kerb is a structure made of concrete or stone, either physically constructed or painted, that is usually positioned at the edge of a road. Its purpose is to prevent vehicles from straying off the carriageway and potentially provide a clear separation between adjacent lanes.

 

The duties of a precast road kerb and drain worker include installing precast concrete road kerbs and drains, preparing the work site, inspecting the quality of precast elements, joining and sealing them securely, and performing backfilling and repairs. They must also adhere to safety protocols for a safe working environment.
