Concrete Patio Leveling
Why Is My Patio Settling?
The most common reason for patio settlement is due loosely backfilled soils during initial construction around the home. Once the basement or foundation is installed at a depth of several feet, the backfill zone closest to the foundation is filled with disturbed soils. While there are standard compaction practices during the backfill process, these steps are often skipped. As these base soils reconsolidate and settle over several years, so will the concrete patio.
Detached patios away from the home can also be constructed on loose fill that may have been used to level off the natural grade. This built-up soil base can also result in settlement failure.
This issue is also often seen on above grade patios that have been raised and filled next to the home.

Concrete raising when applicable can return the concrete back to its original height and position and may improve or correct some water issues due to negative pitch which has resulted from the concrete settlement.
