Sinking Concrete Slab – Why It Happens and How to Fix It Fast
If you’ve noticed your concrete slab sinking — whether it’s in your driveway, sidewalk, garage, or basement — you’re not alone. A sinking concrete slab is one of the most common and dangerous signs of shifting soil and inadequate support beneath your home or property. It can create trip hazards, drainage issues, and long-term structural problems if left unchecked.
At Force Basements, we specialize in identifying the cause of slab settlement and providing proven concrete lifting solutions to raise and stabilize your concrete — without the need for full replacement.
What Causes a Sinking Concrete Slab?
A slab may begin to sink or settle due to changes in the soil underneath or problems with water management. Common causes include:
-
Soil erosion or washout beneath the slab
-
Poor compaction during original construction
-
Expansive clay soil shrinking or shifting
-
Leaking gutters, downspouts, or plumbing
-
Freeze-thaw cycles that displace the soil
-
Heavy loads placed on unsupported slabs
Once the soil moves or disappears, the concrete loses its support — and the slab begins to drop unevenly or sink.
Why You Shouldn’t Ignore It
Even if the issue starts small, a sinking concrete slab almost always gets worse over time. If ignored, it can lead to:
-
Uneven surfaces and tripping hazards
-
Water pooling near your foundation
-
Cracking and separation in the concrete
-
Structural damage to adjacent walls or floors
-
Difficulty using garage doors, entries, or stairs
-
Major replacement costs down the line
The earlier you address it with professional concrete lifting, the less invasive and expensive the fix will be.
