How To Repair Cracks in Concrete Foundation Walls

The Importance of Repairing Cracks in Concrete Foundation Walls

Every homeowner knows the panic of seeing a crack in their foundation. Fortunately, not all cracks are serious. Keep reading to learn how to repair cracks in concrete foundation walls, as well as how Perma Dry Michigan can help.


With over 20 years of experience in protecting and waterproofing basements, we know the importance of comfortable basements. Even if your crack isn’t serious, it can cause severe problems later if you don’t address it.  

Understanding How Cracks Occur in Concrete Foundation Walls

The primary cause of cracks in your foundation is the soil around your home or business. When soil absorbs moisture, it expands. If the soil is next to your foundation walls, it puts pressure on them, eventually causing cracks.

Foundation cracks fall under one or more of the following categories:


  • Hairline: This is any crack less than an eighth of an inch wide. Almost every home has them, and as long as they don’t get worse, you shouldn’t worry.
  • Vertical: As long as they’re thin and don’t leak water, vertical cracks aren’t serious.
  • Horizontal: No matter the thickness, horizontal cracks are always a cause for concern.
  • Diagonal: A settling foundation often causes diagonal cracks, and a professional can determine their severity.

Why Immediate Foundation Crack Repair Is Crucial

What happens if you don’t seek concrete foundation repair quickly? Moderate to severe cracks can cause the following problems:


  • Cracking drywall in your basement or throughout your home
  • Widening gaps between your windows and exterior walls
  • Increasingly large cracks in your foundation
  • Warping of your floors and ceilings
  • Mold growth, which can spread throughout your entire home, causing serious health issues


At Perma Dry Michigan, we can quickly repair foundation cracks to keep your family safe and healthy and avoid more expensive repairs. If you notice a new severe crack or see a hairline crack that’s grown worse, contact us.

The Process of Professional Repair of Cracks in Concrete Foundation Walls

How do we repair cracks in concrete foundation walls? We use the following steps:


  1. We hammer nails halfway deep and spaced 12 inches apart. This allows us to adequately align the epoxy injectors.
  2. We mix the epoxy to prime it for filling the crack.
  3. We slide a plastic injector port over each nail.
  4. We seal the crack with a layer about one-eighth inch thick.
  5. After the sealant settles (about ten hours later), we use the injector port to insert the epoxy deep into the crack.
  6. We seal and cut away the injection ports.
