What is hoarding (construction)?
A temporary protective barrier erected around a demolition or excavation site to shield the public, secure the work area, and contain dust and debris.
On Ontario demolition and excavation sites, hoarding refers to the temporary fencing or wall system that surrounds the active work zone. This perimeter barrier protects pedestrians and nearby properties from flying debris, falling materials, and other hazards inherent to demolition work. It also restricts unauthorized access to the site and keeps equipment and materials secure from theft or vandalism.
Hoarding typically consists of plywood panels, metal frames, or mesh screening attached to a sturdy post structure. The height and material specifications depend on the site conditions, the scale of the demolition, and local municipal bylaws. Sites in dense urban areas often use solid opaque hoarding to block sightlines and contain dust, while some sites employ wind-fencing mesh for lighter dust control.
Beyond safety and security, hoarding serves an environmental function by containing dust and particulate matter during demolition activities. This is especially important in residential neighborhoods and areas near schools or hospitals. Many demolition contractors factor hoarding installation and removal into their project timeline and budget as a standard part of site preparation and closure.
Municipal inspectors typically require hoarding to remain in place throughout demolition and excavation work until the site has been properly cleared and restored. Contractors must ensure hoarding is properly maintained, free of gaps or damage, and compliant with local regulations.
