About St. Boniface and its foundations
Age plus rivers plus gumbo is a demanding combination. Many St. Boniface and Norwood homes were built when foundations were shallower and drainage less understood, so after a century of seasonal swelling and shrinking, settlement and cracking are widespread.
The neighbourhood's position between the Red and Seine rivers means the surrounding clay saturates heavily during high water, driving big swell cycles that push on walls and heave footings. Older mortar joints and original concrete simply were not built to absorb a century of that movement.
What we typically see in St. Boniface

- Horizontal and stair-step cracks in aging block and concrete.
- Bowing basement walls from saturated, river-fed clay pressure.
