A construction site can have plenty of fencing and hoarding and still have a problem with vehicle movement. That is where a Jersey concrete barrier comes into the picture. Unlike a lightweight temporary fence, it is designed to provide a substantial physical separation between vehicles, work areas and other parts of a site. So, what\'s a jersey concrete barrier, and when should a construction project consider using one? A Jersey concrete barrier is a heavy precast concrete barrier with a shaped profile that allows barriers to be positioned together to create a continuous protective line. They are commonly considered where a project needs physical separation rather than simply a visual boundary. For Perth construction sites, that distinction matters. A barrier beside a vehicle route has a very different job from a fence around a pedestrian-only work area.
