Foundation repair
Cracks, settlement, a column or a load-bearing wall: we repair, stabilize and reinforce your building, following the engineer's recommendations when they are required.
The foundation carries the entire building. A crack that widens, a floor that slopes or a door that sticks are often the first signs of movement: acting early generally limits the extent of the work.
I
We work on concrete, block and stone foundations, and on structural elements: columns, footings, beams and walls. Here is the work we do most often.
Epoxy injection fills the crack under pressure with a resin that hardens through the thickness of the wall; mortar repair suits cracks and deteriorated areas that need filling. We work from the inside or the outside, depending on access.
Water, frost and time wear foundations down. We repair the affected areas and strengthen the walls so they can resist soil pressure. On a stone wall, a lime resurfacing on the inside can complete the work.
A partial collapse or a badly deteriorated section calls for a quick response. We secure the site, hold up the structure with temporary shoring, then demolish and rebuild the section according to the engineer's plans.
An uneven or sunken concrete floor can point to a problem under the slab. We find the cause, prepare the base, set up the formwork and pour the concrete for a level surface. We also rebuild concrete sidewalks and steps.
A rusted, rotted or poorly supported column weakens the beam it carries. We replace the column and, if needed, its footing: the wider concrete base that spreads the load over the soil.
The structural engineer sizes the new beam, in steel or glulam, and its supports. We build a temporary wall, remove the old wall, install the new structural element and redo the affected finishes.
Hand excavation in tight spaces, or machine excavation when access allows, to expose a foundation or pour support concrete. A request to locate underground utilities is made to Info-Excavation at least 4 business days before digging.
II
Not every crack is serious. Here is how we classify what you see in your basement during a visit.
Some hairline cracks appear as the concrete cures. If it does not move and stays dry, a targeted repair is generally enough.
A crack that widens, doors and windows that stick or an uneven slab point to movement. A site visit tells you whether an engineer's opinion is needed.
A crack that lets water in, a wall that is moving or a rusted or poorly supported column needs prompt work, often under shoring.

Every job follows the same written process, from the visit to final acceptance of the work.

Municipal permits are generally obtained by the owner, in coordination with us, and are not included in our quotes.

We do foundation and structural work in Montreal, on the North Shore, including Laval, and on the South Shore, from our office in Anjou, in Montreal's East End.
VI
Cracks in the walls or slab, uneven floors, moisture in the basement, doors and windows that stick. A site visit tells you whether a targeted repair is enough or whether an engineer's opinion is needed.
No. Some hairline cracks appear as the concrete cures. A crack that widens, lets water in or comes with movement of the wall should be assessed.
Yes, if a structural engineer designs the beam and its supports, and a temporary wall holds up the structure during the work. A permit may be required: it is generally obtained by the owner, in coordination with us, and is not included in our quotes.
Not always for a non-structural crack. To replace a column or a load-bearing wall, underpin a foundation or build an extension, a report or plans signed and sealed by an engineer who is a member of the Ordre des ingénieurs du Québec (OIQ) are generally required.
Before digging, a request to locate underground utilities (gas, electricity, telecommunications, etc.) must be made to Info-Excavation at least 4 business days before the work starts, as the RBQ points out. The request is free and stays valid until the end date of the work entered, for up to 180 days. We make it before every excavation.
Our prices are based on the current wage rates of the Commission de la construction du Québec (CCQ), set by the collective agreements for the sector concerned (residential, institutional and commercial, industrial), plus the materials and equipment specific to each job. Every quote is free, detailed and prepared after a site visit.
A thin, dry crack in a concrete foundation (the "solage", as it is called in Quebec) often comes from concrete shrinkage. It becomes a concern if it widens, lets water through, forms a staircase pattern in a block wall, or if a floor starts to slope and doors start to stick. In those cases, have the foundation assessed: we work from your engineer's report when one is required.
