Parts of masonry break away or entire parapet collapses outwards onto footpath.
Potential structural strengthening project
Holes are cored down vertically into the body of the wall, to well below the support level of the roof. Reinforcing dowels are then grouted into these holes.
Ties are fitted horizontally through the parapet, securing it to the roof and/or a timber deck structure (diaphragm).
Possible first steps with a structural engineer
They assess the structural capacity of the parapet and provide specifications for the vertical dowels and horizontal ties.
