Comparison
Polyjacking vs mudjacking
Both methods lift settled slabs by pumping material beneath them. They differ in material, equipment and characteristics.
Side-by-side
| Polyjacking | Mudjacking / slabjacking | |
|---|---|---|
| Material | Expanding two-part polyurethane | Cement-based slurry (grout) |
| Hole size | Generally smaller | Generally larger |
| Material weight | Lightweight foam | Heavy; adds load to soil |
| Water sensitivity | Closed-cell foam is water-resistant | Can erode if water flows beneath |
| Cure | Product dependent | Longer; depends on mix and conditions |
| Cost | Depends on job and product | Depends on job and mix |
When each may be chosen
Polyurethane is often preferred where lighter material, smaller holes or water resistance matter. Mudjacking may still suit some large or budget-sensitive jobs. A contractor should explain why they recommend one method for your site.
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.
