Abstract
The subject invention provides a rock catchment barrier comprising a plurality of modules. Each module comprises a concrete base having a top surface, a post, a concrete barrier, an aperture for connecting the post to the top surface of the concrete base, a connector for connecting the concrete barrier to either side of the concrete base, and a fence panel for catching rocks, the fence panel being attachable to the post, wherein when the concrete base is connected to the concrete barrier, and the post is connected to the concrete base and the fence panel for catching rocks, a resulting module is formed. The rock catchment barrier provides protection for use in a rock excavation or scaling site where there is a need to stop rocks which are projected away from the site, such as when the rock excavation or scaling site is adjacent to a flow to traffic.
