Reasons for Basement Wall Cracks and How to Fix Them


Basement Wall Cracks and How to Fix Them

A majority of homeowners may not realize that improper yard grading can lead to serious issues with basement wall cracks. When it rains, water can flow towards your foundation instead of away from it, ultimately causing damage. This moisture can erode the concrete, leading to those frustrating cracks. While regrading your yard can help fix the problem, repairing the cracks themselves can be a complex task. It often requires specialized tools like crawl space jacks and push piers.


Rather than trying to handle this challenging repair on your own, it's wise to consult with basement wall repair experts. They can offer a free foundation inspection and help you find the right solution to keep your basement safe and sound. Keep reading to know the causes and how to fix crack in basement wall effectively!


The Reasons Behind Cracks in Basement Walls


Basement wall cracks can be a major concern for homeowners, often indicating issues with the foundation. These cracks can arise from various environmental factors, including erosion, frost heaves, flooding, and drought.


Unfortunately, many of these factors are beyond our control, from natural events like heavy rains and freezing temperatures. Here are the common causes of basement wall cracks and how you can address them.


1. Soil Saturation


Soil saturation occurs when the ground becomes overly wet, especially after heavy rainfall. When the soil beneath your basement's footings gets too saturated, it can lead to settling, which may cause cracks in the walls. If you notice cracks forming, it could be due to issues like clogged gutters or improper grading. Consulting a foundation repair specialists can help you identify and fix these problems before they worsen.


2. Pressure Points


Cracks can also develop at pressure points, often occurring when gas or sewer lines are installed. These installations can weaken the concrete, making it more prone to cracking. If you see cracks near windows or corners of walls, it's essential to have them evaluated by a professional to prevent further damage.


3. Drought


Drought conditions can lead to cracks in your basement walls as well. When the soil dries out, it can shrink and cause the foundation to shift. This is particularly true if you have plants near your foundation, as their roots may absorb moisture from the soil, worsening the issue. Keeping an eye on your yard's moisture levels during dry spells can help prevent these problems.


4. Foundation Settlement


Over time, all homes experience some degree of foundation settlement. This settling is usually uniform, but sometimes it can occur unevenly, leading to cracks in your basement walls. Homes built on loose soil are particularly vulnerable to this issue. If you notice uneven floors or cracks, it may be time to consult a professional to assess your foundation.


5. Earthquakes


In areas prone to seismic activity, earthquakes can cause significant damage to your foundation. The shaking from an earthquake can disturb the soil beneath your home, leading to cracks in the foundation. If you live in an earthquake-prone region, knowing how these natural events can impact your home's stability is essential.


6. Concrete Shrinkage


When concrete is poured, it expands while wet and shrinks as it dries. If the concrete is not mixed or poured correctly, it can lead to cracks. Factors like humidity and the specific mix used can affect how the concrete dries. Ensuring proper installation is crucial to preventing these issues from arising.


7. Roots of Trees


Tree roots can be a hidden threat to your foundation. During dry seasons, roots will search for moisture and can extend towards your home. If they find water under your foundation, this can cause the surrounding soil to shrink, leading to cracks. To prevent this, consider removing any trees or shrubs that are too close to your home.


8. Inadequate Grading


Poor grading around your home can lead to water pooling near the foundation, increasing the risk of cracks. If a crack is left unrepaired, it can eventually leak, causing more consequential issues. It's wise to address all cracks promptly and consider having a basement wall repair professional assess your property's grading to prevent future problems. Investing in proper grading can save you from costly repairs later on.


The Importance of Cracked Basement Wall Repair


 Importance of Cracked Basement Wall Repair

It might be easy to overlook cracks in your basement walls since they are quite common, but ignoring them is not a good idea. Even small cracks can lead to serious structural issues if left unattended. Cracks don’t repair themselves; instead, they tend to grow larger over time. It can create even more cracks, allow water to seep in, cause walls to lean, and eventually damage your home's structure. Various basement foundation repair methods exist to fix the issue, and the right one will depend on what's causing the problem.


Finding the Right Repair Method for Basement Cracks


So, how to fix crack in basement wall? When fixing cracks in your basement, choosing the right repair method is essential for maintaining your home’s safety and stability. The most common type of crack is the “hairline” crack, which is very thin and often harmless. Even these small cracks should be addressed promptly to prevent them from worsening. Here are the best repair methods for different types of cracks and how to tackle them effectively.


Understanding Hairline Crack Repairs


Hairline cracks are minor and typically easy to fix. Because they are so thin, they often go unnoticed, but they can still lead to bigger problems if ignored. The best way to repair them is through epoxy injections. This process involves injecting a special epoxy material into the crack to fill it completely. The epoxy hardens and seals the crack, preventing moisture from entering and stopping further damage.


The Process of Epoxy Injection


Repairing cracks with epoxy involves a few simple steps. First, small ports are inserted into the crack to guide the epoxy into place. These ports are spaced about 6 to 12 inches apart. An injection tool forces the epoxy through the ports until the crack is filled. Once the epoxy has dried, which can take a few days to weeks, depending on humidity, the ports are removed, and the area is sanded for a smooth finish. This method effectively ensures that the crack is securely sealed.


Addressing Stair-step or Horizontal Cracks Promptly


Unlike hairline cracks, more serious cracks, such as stair-step or horizontal cracks, require immediate attention. These cracks often indicate structural issues caused by hydrostatic pressure from water buildup around your foundation. If you notice these types of cracks, it’s crucial to consult a professional right away. Ignoring them can lead to major damage, including wall bowing and potential collapse.


Recognizing Uneven Settling Issues


All homes settle over time, but uneven settling can create distinctive crack patterns that signal trouble. If one part of your foundation sinks more than others, it can cause stress on the building materials, leading to cracks in walls and ceilings. Signs of uneven settling include cracks around doors and windows, sticking doors, and foundation cracks. If you observe these symptoms, it’s important to have a basement foundation repair professional evaluate your home to determine the best repair strategy.


By understanding the different types of cracks and their repair methods, you can take proactive steps to protect your basement and maintain the integrity of your home.


Take Action on Basement Wall Cracks!


Basement wall cracks should not be ignored, as they can lead to bigger problems if left untreated. It's important to identify the type and cause of each crack to determine the best repair method. While homeowners often fix small vertical cracks, horizontal or severe cracks need professional evaluation.


Acting quickly and using the right basement wall repair techniques can help maintain your home's foundation and keep your basement dry and safe. When hiring a contractor, ensure they are reputable, insured, and accredited by the Better Business Bureau. Experienced basement repair experts will help keep your home strong and secure for years.
