Common Types of Concrete Cracks (And What They Really Mean)

Surface Cracks (Hairline Cracks)

 

These thin cracks often appear as concrete cures or after weather exposure. While they may look minor, they allow water to seep in. When that water freezes and expands, cracks widen and worsen over time. 

 

 

Spalling Concrete

 

Spalling happens when the top layer of concrete flakes and/or crumbles. This is usually caused by moisture and freeze-thaw cycles when water enters into the exposed concrete pours and freezes, breading down the concrete's surface. Over time, spalling weakens the surface and makes your concrete look worn, old and damaged. 

 

Concrete Deterioration

 

Deterioration is a gradual breakdown caused by weather, age or improper installation. 

Signs of concrete deterioration include:

• Scaling

• Surface pitting

• Uneven texture

• Widening cracks

When left untreated, concrete deterioration can lead to more serious structural issues. 

 

 

Settlement Cracks and Sunken Slabs

 

If your concrete is sinking or separating, the problem likely starts below the surface. 

 

Common causes of sinking concrete and cracking concrete include:

• Poorly compacted soil

• Water erosion

• Drainage problems

• Natural soil movement

When soil shifts or the soil erodes, voids form beneath the concrete slab which causes cracking, sinking and trip hazards.

 

How we repair and protect your concrete.

 

We take a complete approach to concrete repair including the following steps and products:

• Concrete leveling with PolyLevel Foam:
  • We inject high-density polyurethane foam beneath the slab to fill voids, stabilize the soil and lift concrete back into place within hours or even minutes.
• Joint and crack caulking and sealing with NexusPro:
  • Open concrete joints and concrete cracks allow water to seep below the slab, leading to soil erosion and settlement. NexusPro Joint Sealant provides a flexible, long-lasting seal that keeps moisture out to prevent soil erosion. 
• Surface protection with SealantPro
  • SealantPro creates a protective barrier that helps resist water infiltration and freeze-thaw damage. This concrete sealant penetrates into the concrete's pours and bonds with the concrete chemically, this will help extend the life of your concrete. 

 

Don't ignore small cracks

 

Small cracks can quickly turn into sinking slabs and costly repairs. Addressing the issue early protects your property's safety, appearance and value.
