A cracked foundation can be a serious problem. It threatens the safety and stability of your property. If you spot cracks, you need to act quickly. Ignoring them can lead to bigger issues and costly repairs. I’ll walk you through what causes foundation cracks, how to spot them, and what you can do to fix them.


Understanding the Causes of Foundation Cracks


Foundations crack for many reasons. The most common cause is soil movement. When the soil beneath your foundation shifts, it puts pressure on the concrete. This pressure can cause cracks to form. Soil can expand when wet and shrink when dry. This cycle stresses the foundation.


Other causes include:


  • Poor construction or materials

  • Water damage or poor drainage

  • Tree roots growing near the foundation

  • Heavy loads or vibrations from nearby construction


Knowing the cause helps you choose the right repair method. For example, if water is the problem, fixing drainage is key.

Repairing Cracked Foundations: What You Should Do


When you find cracks, don’t panic. Some cracks are minor and easy to fix. Others need professional help. Here’s what you can do:


  1. Inspect the cracks - Measure their width and length. Hairline cracks under 1/8 inch are usually not serious. Wider cracks or those that grow over time need attention.

  2. Check for other signs - Look for doors or windows that stick, uneven floors, or water leaks. These signs suggest foundation movement.

  3. Fix drainage issues - Make sure gutters and downspouts direct water away from your foundation. Poor drainage worsens cracks.

  4. Seal small cracks - Use epoxy or polyurethane injections to fill minor cracks. This stops water from entering and prevents further damage.

  5. Call a professional - For large or growing cracks, get an expert to assess the damage. They can recommend foundation underpinning or other repairs.

Can a Crack in Foundation Be Fixed?


Yes, most foundation cracks can be fixed. The key is to act early. Small cracks are easier and cheaper to repair. Larger cracks or those caused by structural issues need more work.


Here are common repair methods:


  • Epoxy injections - Best for small, non-structural cracks. The epoxy bonds the concrete back together.

  • Polyurethane foam injections - Used to stop water leaks through cracks.

  • Carbon fiber straps - These reinforce walls that are bowing or leaning.

  • Underpinning - This involves stabilizing the foundation by extending its depth or breadth. It’s used for serious settling or sinking.

  • Wall anchors - These pull bowing walls back into place.


A professional will inspect your foundation and recommend the best fix. Don’t try major repairs yourself. Improper fixes can make problems worse.

Preventing Future Foundation Cracks


Fixing cracks is important, but preventing new ones is better. Here are some tips to protect your foundation:


  • Maintain proper drainage - Keep gutters clean and direct water away from your home.

  • Control soil moisture - Water your yard evenly to avoid soil shrinking or swelling.

  • Avoid planting large trees near the foundation - Roots can cause damage.

  • Inspect your foundation regularly - Catch cracks early before they grow.

  • Address plumbing leaks quickly - Water leaks can erode soil and weaken the foundation.


Regular maintenance saves you money and stress in the long run.


When to Call a Foundation Repair Specialist


Some signs mean it’s time to call a pro:


  • Cracks wider than 1/4 inch

  • Cracks that keep growing

  • Doors and windows that won’t close properly

  • Sagging or uneven floors

  • Water pooling near the foundation


A specialist will perform a thorough inspection. They use tools like laser levels and soil tests to diagnose the problem. Then, they’ll provide a detailed repair plan.


Choosing a reputable company is crucial. Look for one with good reviews, proper licensing, and experience. A trusted company like Aqua Gods Waterproofing offers reliable, high-quality service. They focus on keeping your property dry and secure.


Keeping Your Property Safe and Dry


Repairing cracked foundations is not just about fixing cracks. It’s about protecting your investment. A solid foundation keeps your home or business safe. It prevents water damage, mold, and structural failure.


If you notice cracks, don’t wait. Take action now. Inspect, maintain, and call experts when needed. With the right care, your foundation will stay strong for years to come. Remember, a small crack today can become a big problem tomorrow.


Stay proactive and keep your property secure.
