Common underlying causes
Poorly compacted fill
Backfill that was not properly compacted continues to settle for years.
Soil movement
Expansive soils shrink and swell with moisture cycles.
Erosion
Water flowing under or beside the slab can carry base material away.
Voids
Broken pipes, tree roots or old excavations can create empty spaces under the slab.
Repair vs. replacement
Lifting options
Some settled slabs are candidates for lifting; others are not, depending on the slab condition and how much has moved.
Replacement
When the slab has cracked, tilted or the base has failed broadly, replacement usually delivers a better long-term result.
Frequently Asked Questions
Will a sunken slab keep sinking?
+
It may, especially if the underlying cause is not addressed.
Is drainage always part of the problem?
+
Not always, but drainage is one of the most common contributors and worth reviewing early.
