Spalling Concrete And Slab Foundations

Spalling Concrete And Slab Foundations
Table of Contents

Do you have spalling concrete? While concrete is a durable material, it will break down over time or need repair. Concrete slab foundations experience many problems, from cracks to settlement. But there are indicators other than cracks that can tell you that a problem may be around the corner. One of those indicators is spalling.

What is spalling concrete?

Spalling is when pieces of concrete crack and flake off. Spalling is also sometimes referred to as concrete scaling.

Causes of spalling concrete

Spalling is caused by water entering the concrete, causing the surface to flake or peel off. Spalling happens when there’s too much moisture in the concrete.

Spalling happens in concrete bricks – which are common in some – and in poured concrete. It happens more often in areas with a high level of salt in the water and a freeze/thaw cycle. De-icing agents also contribute to spalling. If you’ve seen the effect of salt on concrete during the winter, you’ve probably seen spalling.

What is concrete scaling?

Scaling is another term for spalling used by concrete contractors. This name refers to the scale-like pieces of concrete that flake off.

Does spalling mean you have slab foundation problems?

Not necessarily, but you shouldn’t ignore the problem. Spalling in foundation walls might mean there’s a high water level around your foundation.

If you see spalling, look around for other signs of foundation problems such as:

  • Foundation cracks
  • Sloping floors
  • Wet crawl spaces or basements
  • Windows and doors that don’t open or close properly
  • Drywall cracks
  • Ceiling cracks
  • Floor cracks
  • Countertops that are pulling away from the walls

If you notice any other signs of foundation problems, contact a foundation repair contractor for an inspection.

Never ignore changes to your home’s foundation and if you see any, contact a professional right away. Foundation repairs can be costly and will cost more if you wait.
