Basement Underpinning
Extend your foundation downward to safely create high-ceiling living space in existing homes.
Toronto's housing stock is unusually demanding. We work daily on 140+ year-old heritage homes with rubble and brick foundations, tightly packed downtown townhouses, and semi-detached properties where a shared party wall dictates every move. Each of those structures needs a different underpinning sequence, and we plan yours before excavation begins.
Underpinning removes soil beneath your existing footings in small, engineered sections and replaces it with new reinforced concrete poured to a deeper elevation. Because only a limited length of wall is ever unsupported at once, the building above stays structurally safe, your neighbours stay protected, and the finished basement gains real, code-compliant ceiling height.
How We Help
- Sequential pin-by-pin excavation for absolute foundation safety
- Heritage home foundation restoration (140+ year-old brick & masonry)
- Maximizes ceiling clearance without compromising neighboring structures
- WSIB covered with fully engineered sign-offs

We assess your foundation, soil, and load paths on site, then engage our structural engineer.
Stamped drawings and City of Toronto permits are handled end to end before a shovel moves.
Pin-by-pin excavation and reinforced concrete pours keep the structure fully supported throughout.
Engineer and municipal inspections, cleanup, and a written workmanship guarantee.
