What is underpinning?
Underpinning is the process of extending a foundation down to stronger, more stable soil, or transferring its load onto piers that reach that soil. It is the standard fix when a foundation has settled, sunk, or is no longer adequately supported by the ground beneath it.
How much does foundation underpinning cost in Regina?
Major underpinning and piering projects in Regina typically cost $24,000 to $60,000 or more. The price depends on how many piers are needed (usually 10 to 30), the method, access, and how far the foundation has moved. A free on-site assessment with an elevation survey gives you an exact quote.
| Job | Typical cost (CAD) |
|---|---|
| Minor crack repair (polyurethane injection) | ~$500 to $1,500 |
| Moderate repair (multiple cracks + drainage) | $2,200 to $8,100 |
| Major underpinning / piering project | $24,000 to $60,000+ |
When do you need underpinning instead of crack repair?
You need underpinning when the foundation is actively settling, not just leaking. Signs include sloping or sinking floors, doors and windows that have shifted out of square, widening stair-step cracks, and gaps opening between walls and ceilings. Sealing a crack will not help if the soil under the footing is giving way.
Underpinning methods we use in Regina
- Helical (screw) piles, driven below the 6 ft frost line, low vibration, often year-round, about $300 to $700 per pile.
- Push / resistance piers, hydraulically driven using the home's own weight as resistance; project-dependent pricing.
We recommend the method based on your soil, load, and access. Compare all methods.
Do I need a permit for underpinning in Regina?
Yes. Structural foundation repairs such as underpinning require a City of Regina building permit, which your contractor handles. We pull the permit and coordinate inspections as part of the project.
Frequently asked
How long does a full underpinning project take?
Most Regina homes are underpinned in 3 to 7 working days once permits are issued, depending on pile count and access.
Do I need to move out?
No. Underpinning is performed from outside or from interior trenches. Homes remain occupied through the work in almost all cases.
