Is mudjacking a permanent fix?

Not always. One published driveway repair guide treats every repair as temporary, even if some hold for many years, and warns that if roots or a leaking pipe are eroding the ground under a slab, replacing it may be the only choice.

The International Association of Certified Home Inspectors lists cases where mudjacking is not appropriate, among them settling whose cause is never addressed and slabs that have risen on expansive soil rather than sunk. Around Waco, the USDA soil survey gives Houston Black clay a very high shrink-swell potential.
