When mudjacking may work
It may be used for voids under concrete or limited slab settlement. It is less likely to solve deep soil movement or structural load issues.

Questions to ask
- What failure mode are you diagnosing, and what evidence supports it?
- Does this quote include permits, engineering, cleanup, and warranty terms?
- Which line items are required now, and which are optional upgrades?
- How will drainage, grading, or plumbing leaks be ruled out before repair?
- Can you show comparable local projects with similar foundation conditions?

Good for high-price pier, waterproofing, slab, and crawl space quotes.
Avoids collecting payment or sensitive documents on the first pass.
What to ask
Ask what material is injected, how voids were confirmed, whether plumbing leaks were ruled out, and what happens if the slab settles again.

Common Repair Methods
Mudjacking
A contractor should explain why this method fits the observed movement, soil conditions, drainage, and load path before asking for a signature.
Polyjacking
A contractor should explain why this method fits the observed movement, soil conditions, drainage, and load path before asking for a signature.
Void filling
A contractor should explain why this method fits the observed movement, soil conditions, drainage, and load path before asking for a signature.
Drainage correction
A contractor should explain why this method fits the observed movement, soil conditions, drainage, and load path before asking for a signature.

FAQ
Should I use this page as a final repair price?
No. Use it as a planning range only. A final price depends on inspection findings, soil conditions, access, permits, drainage, materials, and engineering requirements.
How many quotes should I compare?
Most homeowners should compare at least two or three written scopes, especially when the repair involves piers, waterproofing, wall stabilization, or structural movement.
