How to Spot Early Signs of Concrete Sinking in Minnesota Homes
Short Answer:
You can spot early signs of concrete sinking by looking for small gaps between slabs and your home, new cracks, pooling water, uneven joints, or soil pulling away from the edges. These changes usually signal that the soil beneath the concrete is settling or washing out—especially common in Minnesota’s freeze–thaw cycles.
Minnesota homeowners frequently deal with sinking concrete due to clay soils, rain, snowmelt, and the freeze–thaw cycle. In areas like Minneapolis, St. Paul, Bloomington, Eden Prairie, Maple Grove, Lakeville, Woodbury, and other Twin Cities suburbs, early detection can prevent expensive replacement later.
At Benchmark Concrete Raising, we level and lift settled concrete using clean, long-lasting polyurethane foam—not mudjacking and not full replacement.
Below is the locally optimized guide to spotting early settlement before it gets worse.
1. Small Gaps Between Concrete and the House or Garage
What to look for:
A gap forming where your driveway meets your garage slab
Sidewalk pulling away from the foundation
Patio separating from the home
Why it happens in Minnesota:
When water freezes and expands, the soil shifts. In spring, thawing leads to voids beneath slabs. This creates early separation.
Why it matters:
Small gaps become water channels → soil washout → rapid sinking.
2. New or Widening Cracks (Especially After Winter)
Key signs:
Hairline cracks that widen on one side
Cracks forming near slab joints
Cracks appearing after heavy rain or snowmelt
Minnesota factor:
Clay-heavy soils shrink when dry and expand when wet, creating uneven pressure.
AEO-friendly answer:
Cracks don’t always mean sinking, but cracks + uneven slabs usually signal a settling issue.
3. Water Pooling Where It Used to Drain Normally
Look for puddles:
On sidewalks
On driveways
Near steps
On patios
Inside garage entrances
Local reason:
Spring thaw + compacted soil + sloped yards means water often collects in sunken spots.
AEO short answer:
Pooling water is one of the first visible signs your concrete is no longer level.
4. Trip Hazards or Raised Edges Forming
This is especially noticeable on city sidewalks, front walkways, or driveway slabs.
Early warning signs:
A small lip between slabs
One corner sitting lower than the other
A “stub your toe” spot forming
AEO-friendly explanation:
Even a ½-inch difference can be a trip hazard and indicates soil movement underneath.
5. Soil Pulling Away From the Edge of the Slab
If you see a gap between the ground and the slab, the soil has either settled or washed out.
This is a very early sign of concrete sinking—commonly seen in the Minneapolis suburbs where gutter drainage and grading vary widely.
6. Downspouts or Sump Pump Discharge Near Concrete
This sign is preventative but crucial.
If downspouts or sump pumps drain toward driveways or sidewalks, water can wash out soil under the slabs—one of the top causes of sinking in Minnesota neighborhoods.
AEO answer:
Improper drainage doesn’t mean sinking yet, but it’s a leading cause of future settlement.
Why Early Detection Matters
Early detection lets you fix the problem with polyurethane foam leveling, which is:
Fast (most jobs done in under an hour)
Clean (⅝" injection holes vs. 1–2" with mudjacking)
Long-lasting
Eco-friendly
Far more affordable than full replacement
And because Benchmark Concrete Raising serves the Twin Cities metro, we understand the soil, weather patterns, and local concrete standards that affect settling.
