Slab settlement vs foundation settlement
Polyjacking addresses slabs — driveways, walkways, garage floors. Foundation movement is a separate issue.
Signs that point to the foundation
- Stair-step cracks in block or brick walls
- Doors and windows sticking or out of square
- Widening cracks in foundation walls
- Floors inside the house sloping noticeably
What to do
If you see these signs, consult a structural engineer or foundation specialist before any slab work. PolyJacking.ca does not provide structural assessments.
Next step: an assessment
Photos help, but the only reliable way to decide whether a slab can be lifted is an on-site look at the concrete, the drainage and the likely cause of settlement. Submit a request and the HAUSE intake team will review it and confirm whether a suitable contractor is available in your area.
