Local considerations for Montreal job sites
Montreal has more than a century of buried utilities, often without reliable plans: lead water service lines, abandoned conduits, old foundations under parking lots and service connections modified over successive renovations. In several sectors, bedrock lies less than one metre below the surface, which brings utilities closer to the surface and makes locating more delicate.

| Green alley, backyard, in-ground pool | Underground utility locating |
