Concrete walls are renowned for their strength and longevity. However, when cracks start to appear, whether as fine hairline fractures or substantial fissures, it can signify hidden foundation issues. These cracks vary in size and orientation (horizontal, vertical, or diagonal) and, though they may seem minor, can worsen, causing significant structural damage if ignored.



However, there is a chance that the source of this issue could be your foundation. Over time, unstable soil beneath your dwelling can cause a foundation shift, leading to unsightly gaps in your walls.

What Causes Cracks in Concrete Walls?

Cracks in concrete walls can occur due to various factors, including:

A concrete shrinkage as a prominent cause of cracks in concrete walls in Berryville, VA

Shrinkage

Concrete walls can develop cracks due to shrinkage, which is the natural reduction in the volume of concrete as it cures. When concrete hardens, it undergoes a chemical reaction that decreases volume, causing stress within the material. 

 

This stress can result in gaps, especially if the concrete mix lacks sufficient curing or if the concrete mix has a high water content or insufficient curing time.

Settlement

Settlement-induced cracks occur when the ground beneath the concrete wall compresses or shifts over time. This can happen due to changes in soil moisture content, poor soil compaction, or natural settling of the building’s foundation. As the soil settles, it exerts pressure on the concrete, leading to gaps. 

 

Proper site preparation, including adequate compaction and drainage measures, can help prevent settlement-related cracks in concrete walls.

Illustration on how thermal changes can cause the formation of cracks in concrete walls in Alexandria, VA

Thermal changes

Concrete expands when exposed to heat and contracts when cooled. Extreme temperature fluctuations can cause concrete walls to expand and contract repeatedly, leading to thermal stress and cracking. 

 

To mitigate this, expansion joints or control joints are often incorporated into concrete structures to allow for controlled movement during temperature changes.

Overloading

Excessive weight or pressure on your concrete walls can cause them to crack. This is more common in cases where the wall was not designed or reinforced to withstand such loads.

 

It’s important to be mindful of heavy loads, such as storage piled against the wall or vehicles parked too close. If you’re planning any significant changes in your space, consult an engineer to ensure the structure can handle the additional weight without developing cracks or structural issues.

Poor Construction Practices

Cracks can occur when contractors don’t follow best practices during concrete placement and finishing. This includes improper mixing and pouring of the concrete, insufficient compaction, inadequate curing, or using low-quality materials. Homeowners should hire experienced and reputable contractors who adhere.

Structural movement

Concrete walls can crack due to structural movements in your property. This can result from settling your foundation, shifting or subsidence over time, or seismic activity in earthquake-prone regions. 

 

Employing proper reinforcement techniques and designing the structure to accommodate movement can help protect against cracks caused by structural shifts.

Environmental Factor

Exposure to harsh environmental conditions can deteriorate concrete. In regions with freeze-thaw cycles, for instance, water can penetrate the concrete and expand when it freezes, causing gaps. Additionally, exposure to aggressive chemicals or salt can weaken the concrete over time. 

 

Selecting concrete mixes and sealants designed for your local climate and environmental conditions can help prevent these types of cracks.

Hydrostatic Pressure

High water tables or poor drainage can exert pressure on the exterior of concrete walls. This hydrostatic pressure can lead to gaps or water infiltration. To combat this, homeowners should ensure proper grading and drainage systems around their property and consider waterproofing solutions to protect against the effects of hydrostatic pressure on the concrete walls.

Should I be worried about cracks in my concrete walls accompanied by bowing?

Yes, you should be worried about cracks in your concrete walls accompanied by bowing. It can indicate structural issues, and when combined with bowing, it suggests that the walls are under significant stress. Bowing typically occurs due to foundation movement or excessive soil pressure against the walls. 


To address this problem, wall anchors are one of the effective solutions. Wall anchors provide support and stability to the walls by transferring the pressure to more stable soil or structural elements. The process involves installing anchors into the ground outside the bowing wall and attaching them to the wall with steel rods, effectively pulling the wall back into its original position and preventing further movement or damage.

How to repair a large crack in an interior concrete block wall?

One effective solution for repairing large cracks in concrete walls is by using push piers. This method involves installing steel piers under the foundation to lift it back into place and stabilize it, helping to close the gaps in the process. Push piers are ideal for walls that have settled due to poor soil conditions or other factors, as they can reach deep into the ground to provide lasting support. 

 

Installing push piers involves digging small holes near the foundation, inserting them through the walls, and then driving them into the ground using hydraulic jacks. The installation can be completed relatively quickly, with minimal disruption to the surrounding area. Overall, push piers offer a reliable and effective way to repair large gaps in interior concrete block walls.

How to prevent cracks in concrete walls from further cracking?

To prevent further cracking in concrete walls, one effective solution is to use carbon fiber reinforcement. Carbon fiber is a strong and lightweight material that can be applied to the wall’s surface to increase its tensile strength. 

 

The process involves cleaning and preparing the wall, using an epoxy or adhesive, and then applying carbon fiber sheets or strips over the surface. The carbon fiber reinforces the concrete, making it more resistant to cracking caused by tension or stress. This solution helps distribute the load evenly across the wall, reducing the likelihood of future cracks.

FAQ's

How can I differentiate between normal settling cracks and those that signify a foundation problem in my concrete walls?

Differentiating between normal settling cracks and those indicating a foundation problem in concrete walls requires careful observation and evaluation. Normal settling cracks are typically small, less than 1/4 inch wide, often hairline in size, appear vertically or diagonally, and are generally uniform in width. They are commonly found in new structures when the concrete cures and adjusts to its surroundings. 

 

On the other hand, gaps that signify a foundation problem are typically wider than 1/4 inch, horizontal, or stair-step and may be accompanied by other warning signs, such as a crack widening over time, or other signs of foundation issues, such as uneven floors or doors that are difficult to close. 

 

If you notice significant or concerning gaps, it is advisable to consult a professional foundation specialist who can assess the situation and provide appropriate guidance and repairs if needed.

What are the dangers of ignoring cracks in concrete walls?

Ignoring cracks in concrete walls can lead to a range of structural issues, which can compromise the stability and safety of your property. When left unaddressed, gaps can deepen and widen over time, allowing water and pests to penetrate the foundation, which can result in mold growth and rot. 


Furthermore, the gaps can cause the walls to bow, sag, or even collapse over time, making your property a hazard to anyone inside or around it. To prevent these risks and ensure that your home remains safe and structurally sound, it’s crucial to seek the guidance of LUX Foundation Solutions as soon as you notice any signs of cracking to identify the underlying problems and fix them before they become more severe. It will give you peace of mind in knowing your home is safe and secure.

How can I prevent foundation problems that lead to cracks in concrete walls?

Preventing foundation problems that can lead to cracks in concrete walls requires proactive measures and regular maintenance. 

 

  1. Ensure proper drainage around your home by maintaining gutters, downspouts, and grading to direct water away from the foundation. 
  2. Monitor and address any signs of water leakage or excess moisture, which can contribute to foundation issues. 
  3. Avoid overloading the foundation by distributing weight evenly and minimizing excessive soil moisture fluctuations through proper landscaping practices. 
  4. Consider periodic inspections by a professional to identify and address any potential foundation concerns before they escalate into cracks in your concrete walls. 

A timely repair can prevent extensive and expensive damage later. By being proactive and seeking professional help, you can avoid further damage to your home and ensure its longevity.

Can I fix concrete cracks in my wall myself?

While it may seem simple to just DIY and patch up your concrete wall cracks, it’s vital to consider the cause beforehand. While it may seem like a cost-effective solution, it could be dangerous and lead to further damage in the long run. 

 

Gaps can be related to different things, such as water damage, foundation movement, or soil expansion – which may require customized repair solutions. Attempting to fix the cracks yourself without determining the root cause could extend the problem and may even lead to more significant issues like water infiltration or structural damage, which can lead to costly repairs

 

It’s best to seek assistance from an expert foundation repair service, who can assess the underlying problem and provide a proper solution.
