Concrete lifting in Ottawa
A practical guide to concrete settlement and polyurethane lifting for Ottawa homeowners and property managers — what causes slabs to sink locally, what to check, and how to request an assessment.
Why slabs settle in Ottawa
Ottawa’s cold winters and areas of sensitive marine clay (Leda clay) mean soil conditions vary considerably; some movement may be soil-related rather than simple settlement.
Commonly reported issues
- Garage approach slabs dropping after thaw
- Patios settling near foundations
Local considerations
- Public sidewalks and boulevards in Ottawa are generally municipal property — contact the city before arranging work on them.
- Call before you dig: buried utility locates are recommended before any drilling near service lines.
- Where sensitive clays are suspected, a geotechnical opinion may be worthwhile.

Questions
Is polyjacking available in Ottawa?
We don’t operate local offices. When you submit a request, it is reviewed by the HAUSE intake team, who look for a suitable contractor or partner. Availability in Ottawa is confirmed after your inquiry is reviewed.
Can the work be done in winter?
Some contractors work in cold weather with suitable products and precautions; others pause for winter. Frozen ground can affect results. Ask about seasonal limits when you are contacted.
What will it cost?
Cost depends on slab size, depth of settlement, void volume, access and the product used. We don’t publish prices; a contractor can provide a quote after assessment.
