Unit paving
Provide base course and bedding to match the existing. Reinstate using whole paving units. Do not use concrete infill.
Rigid (concrete) pavement
Requirement: Reinstate concrete surfaces to the original level. Additional concrete beyond the damaged area shall be removed and replaced back to the nearest existing joint even if undisturbed by the trench works. Where specified, epoxy grout steel dowels into the adjacent concrete and provide reinforcement to prevent the reinstated concrete from subsiding or cracking. Comply with the requirements of Table 8.1.
Surface finish: Where the trench has been constructed longitudinally in the verge with a full width path constructed path, then the final surface repair width is to match the existing surface width (i.e. full width). For Central Business District, Neighbourhood Centres, Suburban Centre Improvement Projects (SCIP) and other high finish areas, reinstate the surface to the finish requirements of the Infrastructure Design Planning Scheme Policy.
