Frequently Asked Questions
Which cracks are worrying?▾
Horizontal cracks, stair-step cracks in block walls, cracks that widen over time and cracks that let water through. A fine, stable vertical crack is generally benign.
Do I need an engineer?▾
For structural movement, settling or before major work, yes. An engineer's report defines the problem and lets you compare quotes on the same basis.
How is a leaking crack repaired?▾
Often by injection from inside for an isolated crack, or by excavation and exterior waterproofing when the wall is at fault over a larger area.
Can this work be done in winter?▾
Interior injection, sometimes. Exterior excavation is better planned from spring to fall.
What warranties should I ask for?▾
A written warranty on the repair, with its term and exactly what it covers. Also ask for proof of insurance and the CNESST clearance.
Foundation & Waterproofing in Montréal: what to know
In a city with old buildings and clay soils in places, foundation problems are common. They range from a harmless crack to structural movement that needs serious intervention.
Not all cracks are equal
A fine vertical crack in a concrete wall is common and often inconsequential. A stair-step crack in a block wall, a horizontal crack, a crack that widens or lets water through are another matter. When in doubt, an engineer's opinion is worth its price before committing to major work.
Piles
When part of the building settles, the answer often runs through piles that carry the load deeper. It is specialised work, with warranties to obtain in writing.
Waterproofing
Redoing exterior waterproofing means excavating along the wall. That is the moment to check the weeping tile as well, since the trench is already open.
Licence
The contractor must hold a Régie du bâtiment du Québec licence, liability insurance and a CNESST clearance.
