Why Concrete Sinks

Learn What Causes Concrete To Sink, Settle, Crack, And Become Uneven Around Homes & Businesses

Concrete may look strong and permanent, but the ground beneath it constantly changes over time. In Wisconsin and Minnesota, changing weather, moisture, and soil conditions can slowly cause concrete slabs to settle, shift, and sink.

At A.L.L. Concrete Raising, we help homeowners, businesses, and municipalities repair sinking concrete with professional concrete raising, mudjacking, and concrete leveling solutions designed to restore safety and stability without costly replacement.

What Causes Concrete To Sink?

Several factors can lead to sinking and uneven concrete around your property.

Soil Washout & Water Erosion

One of the most common causes of sinking concrete is water erosion beneath the slab. Rainwater, poor drainage, leaking gutters, or melting snow can slowly wash away supporting soil under driveways, sidewalks, patios, and concrete slabs.

As the soil washes out, empty spaces or voids form beneath the concrete, causing the slab to crack, settle, or sink.

Freeze-Thaw Cycles

Wisconsin and Minnesota weather creates constant freeze-thaw cycles throughout the year. When moisture enters the soil and freezes, the ground expands. As it thaws, the soil shifts and settles again.

Over time, this movement can create uneven concrete surfaces and settlement problems around homes, businesses, and municipal properties.

Poor Soil Compaction

If the soil beneath concrete was not compacted properly during installation, the ground may slowly settle over time. This is especially common with:

  • New construction areas
  • Backfilled soil
  • Driveways and sidewalks
  • Garage floors and patios

As the ground settles, the concrete above it begins to sink and become uneven.

Heavy Weight & Traffic

Concrete surfaces constantly support weight from:

  • Vehicles
  • Foot traffic
  • Equipment
  • Commercial activity

Over time, this pressure can compress weak soil beneath the slab and lead to sinking concrete problems.

Voids Beneath Concrete

Empty spaces beneath concrete slabs can form from:

  • Soil erosion
  • Water movement
  • Poor drainage
  • Decaying organic material

These voids reduce support beneath the slab and often lead to cracking, sinking, and uneven concrete surfaces.

Common Signs Of Sinking Concrete

You may notice:

  • Uneven driveways
  • Sunken sidewalks or walkways
  • Patio slabs pulling away from the home
  • Pool decks with trip hazards
  • Water pooling near concrete
  • Cracks or separation between slabs
  • Sinking garage floors
  • Unsafe concrete steps

These problems usually become worse over time if left untreated.

How Concrete Raising Helps

Concrete raising and mudjacking help restore settled concrete by filling empty spaces beneath the slab and carefully lifting the concrete back toward its proper position.

This process can often help homeowners and property owners:

  • Avoid costly replacement
  • Reduce trip hazards
  • Improve drainage
  • Restore curb appeal
  • Extend the life of existing concrete
