In a city of 19 boroughs, three water protections<\/span> not to be confused<\/span><\/span><\/h2><\/span>[vc_column_text animation_delay=”0″]Montr\u00e9al has 19 boroughs, covers three quarters of the Island of Montr\u00e9al and had 1,762,949 residents in the 2021 census. The City recommends asking your borough about the regulations in force in your area and the permits you need.<\/span>[\/vc_column_text]<\/span>[vc_column_text animation_delay=”0″]When water shows up in a basement, three different things often get mixed up. The backwater valve<\/strong> keeps wastewater from flowing back into your plumbing. The retention pit<\/strong>, fitted with a pump, receives rainwater from the lot and the foundation drain to prevent overflows. And the French drain<\/strong> is the pipe that collects water at the base of the foundation. A crack in a wall or slab is a fourth path, which is solved by a foundation diagnosis. To judge one, read When Is a Foundation Crack Serious in Quebec?<\/a><\/span>[\/vc_column_text]<\/span>[vc_column_text animation_delay=”0″]Marco R\u00e9paration de Fondation works in Montr\u00e9al on foundation cracks (polyurethane or epoxy injection), French drains (cleaning, repair, replacement or interior drain), waterproofing membranes and excavation around the foundation. Marco assesses every job himself (RBQ license No. 5775-3246-01).
