Understanding Foundation Cracks: Causes and Types

Foundation cracks are a common issue in buildings, both residential and commercial. Understanding the causes and types of foundation cracks is essential for effective repair and maintenance. In this article, we will delve into the various factors that contribute to foundation cracks and the different types of cracks that may occur.

Causes of Foundation Cracks:

  • foundation-cracks-stablwall-1Settling: One of the primary causes of foundation cracks is soil settling. When the soil beneath a building compresses or shifts, it can cause the foundation to crack as it struggles to bear the load.
  • Hydrostatic Pressure: Excessive moisture in the soil surrounding the foundation can exert hydrostatic pressure, leading to cracks. Poor drainage systems and heavy rainfall can exacerbate this issue.
  • Freeze-Thaw Cycles: In colder climates, freeze-thaw cycles can cause the soil to expand and contract, putting pressure on the foundation and leading to cracks over time.
  • Poor Construction: Inferior construction techniques or the use of low-quality materials can also contribute to foundation cracks. Weak concrete or inadequate reinforcement can make the foundation susceptible to damage.

Types of Foundation Cracks:

  • foundation-cracks-stablwall-2Vertical Cracks: These cracks typically run straight up and down and are often caused by settling or the natural curing process of concrete. They can vary in width and length.
  • Horizontal Cracks: Horizontal cracks are more serious and indicate significant pressure against the foundation walls, often due to hydrostatic pressure or expansive soil.
  • Diagonal Cracks: Diagonal cracks usually occur at a 45-degree angle and can be a sign of both settling and lateral pressure. These cracks may start small but can widen over time.
  • Stair-Step Cracks: Common in brick or block foundations, stair-step cracks follow the mortar joints and are indicative of foundation movement or settling.

Foundation cracks can vary in severity, and identifying the underlying causes is crucial for effective repair and prevention. By understanding the different types of cracks and their root causes, property owners can take proactive measures to address foundation issues before they escalate.

Foundation Cracks and Your Home’s Health

Your home’s foundation is more than just a structural element; it’s the cornerstone of your property’s stability and overall health. Foundation cracks, often overlooked or dismissed, can be the starting point for a cascade of issues that can impact the well-being of your home. In this comprehensive guide, we will explore how foundation cracks can have far-reaching consequences, from structural integrity to indoor air quality and everything in between.

The Anatomy of Foundation Cracks

1. Types of Foundation Cracks

Foundation cracks can take various forms, each indicative of different underlying issues:foundation-cracks-stablwall-1

Vertical Cracks: These typically result from settling, which is a natural part of a home’s aging process. While not always a cause for alarm, they can lead to more severe issues if not addressed early.

Horizontal Cracks: Horizontal cracks are a sign of significant pressure against the foundation, often from expansive soil or waterlogged conditions.

Stair-Step Cracks: These zigzagging cracks are common in brick or concrete block foundations and often indicate shifting or settling.

Diagonal Cracks: Diagonal cracks may be a sign of subsidence, which occurs when the soil beneath the foundation shifts or erodes.

2. Causes of Foundation Cracks

Understanding the underlying causes of foundation cracks is crucial:

Soil Shrinkage and Expansion: Soil naturally expands when wet and contracts when dry, which can put significant pressure on your foundation.

Poor Drainage: Improper drainage can lead to water pooling around your foundation, increasing the risk of cracks and other damage.

Tree Roots: The roots of nearby trees can infiltrate the soil beneath your home, causing it to shift and potentially lead to foundation cracks.

Construction Flaws: Poor construction practices or materials can weaken the foundation over time.

Structural Implications

Foundation cracks are not just cosmetic issues; they can have far-reaching structural consequences:

1. Compromised Load-Bearing Capacity

Foundation cracks weaken the structural integrity of your home, making it less capable of supporting the weight of the building. This can lead to sagging floors, slanting walls, and in extreme cases, even structural failure.

2. Leaks and Water Intrusion

Foundation cracks create openings through which water can enter your home. This can result in basement flooding, damage to walls and floors, and the growth of mold and mildew. Water intrusion can also damage electrical and HVAC systems, leading to costly repairs.

3. Pest Infestations

Small foundation cracks can be entry points for pests like termites, ants, and rodents. Once inside, these pests can cause significant damage to your home’s structure and pose health risks to your family.

Impact on Indoor Air Quality

Foundation cracks can affect the indoor air quality of your home, which can have direct implications for your family’s health:

1. Mold and Mildew Growth

Excess moisture entering your home through foundation cracks creates an ideal environment for mold and mildew growth. Exposure to mold spores can trigger respiratory issues, allergies, and other health problems.

2. Radon Gas Infiltration

Radon is a colorless, odorless, radioactive gas that can seep through foundation cracks and accumulate in your home. Prolonged exposure to radon gas is a known carcinogen and is associated with an increased risk of lung cancer.

Impact on Energy Efficiency

Foundation cracks can compromise your home’s energy efficiency in several ways:

1. Air Leaks

Foundation cracks can allow conditioned air to escape and unconditioned air to enter your home. This results in increased heating and cooling costs and a less comfortable living environment.

2. Insulation Compromise

Insulation beneath your home can become compromised due to moisture infiltration. Wet insulation loses its effectiveness and may need to be replaced, further impacting your home’s energy efficiency.

Preventive Measures and Remediation

While the consequences of foundation cracks can be daunting, there are preventive measures and remediation steps you can take:

1. Regular Inspections

Regularly inspect your home’s foundation for any signs of cracks, whether they are internal or external. Early detection is key to preventing further damage.

2. Proper Drainage

Ensure your property has proper drainage systems in place to divert water away from the foundation. This includes well-functioning gutters and downspouts.

3. Foundation Repair

If you identify foundation cracks, consult with a professional foundation repair specialist. Depending on the severity and type of cracks, they can recommend solutions such as epoxy injections, carbon fiber reinforcement, or complete foundation replacement.

4. Radon Testing

Consider testing your home for radon gas. If elevated levels are detected, mitigation systems can be installed to prevent its entry into your living spaces.

The Cost of Inaction

Choosing to ignore foundation cracks can lead to dire consequences:

1. Increased Repair Costs

The longer you delay addressing foundation issues, the costlier the repairs become. What starts as a minor crack can escalate into a major structural problem, resulting in extensive, costly renovations.

2. Reduced Property Value

Foundation issues can significantly reduce the value of your property. Even if you’re not planning to sell, a depreciated property is a less valuable asset.

3. Health Implications

Ignoring foundation cracks can lead to health problems for you and your family. Mold, radon gas, and pests can all pose health risks that are easily preventable with timely action.

Foundation Cracks: The Urgent Need for Immediate Repair

The foundation of your home is its literal bedrock, supporting the entire structure above it. A damaged or cracked foundation can spell disaster for your property, leading to a cascade of issues that can be expensive and challenging to rectify. In this article, we’ll explore the various types of foundation cracks, the reasons behind their occurrence, and why immediate repair is essential for the well-being of your home.

Types of Foundation Cracks

Before diving into the urgency of foundation crack repair, it’s important to understand the different types of cracks that can afflict your home’s foundation:

Vertical Cracks: These cracks typically run straight up and down and are often caused by settling or minor shifts in the soilfoundation-cracks-stablwall-1 beneath your home. While vertical cracks are less severe than others, they can still allow moisture and pests to infiltrate your foundation.

Horizontal Cracks: Horizontal cracks are a cause for greater concern. These cracks usually occur due to significant pressure from the surrounding soil, and they can signify a foundation that is starting to fail.

Diagonal Cracks: Diagonal cracks can appear at a 45-degree angle and are often indicative of structural stress or foundation movement. These cracks can worsen over time, making timely repair crucial.

Stair-Step Cracks: Stair-step cracks resemble a flight of stairs and typically occur in brick or block foundations. They can be caused by the natural settling of your home or external forces like soil pressure.

Reasons for Foundation Cracks

Foundation cracks can be caused by a variety of factors, both natural and man-made:

Soil Settlement: As the soil beneath your home settles or shifts, it can create stress on the foundation, leading to cracks. This is a common cause of vertical cracks.

Hydrostatic Pressure: Water is a powerful force that can exert immense pressure on your foundation walls. Excessive moisture in the soil around your home can lead to horizontal or diagonal cracks.

Poor Construction: Inferior construction materials or techniques can contribute to the formation of foundation cracks. This underscores the importance of hiring experienced professionals for your home’s foundation.

Tree Roots: The roots of large trees near your home can infiltrate the soil beneath the foundation, causing pressure and cracking.

Freeze-Thaw Cycles: In regions with cold winters, the expansion and contraction of soil due to freeze-thaw cycles can lead to foundation damage over time.

Why Immediate Repair is Crucial

Structural Integrity

The most pressing reason to repair foundation cracks promptly is to preserve the structural integrity of your home. Foundation cracks can compromise the stability of your house, leading to uneven settling and potentially catastrophic structural failures. Addressing cracks early can prevent costly and extensive repairs down the line.

Prevent Water Infiltration

Foundation cracks provide an easy entry point for water, leading to basement leaks and moisture-related problems. Water infiltration can exacerbate the existing cracks and create new ones, accelerating the deterioration of your foundation.

Mold and Mildew

Moisture in your basement or crawl space, resulting from foundation cracks, can create an ideal environment for mold and mildew growth. Mold can cause health problems for your family and necessitate expensive remediation efforts

Pest Infestations

Foundation cracks also offer an entry point for pests like termites and rodents. These unwelcome intruders can wreak havoc on your home’s structure and require costly pest control measures.

Reduced Property Value

An unrepaired foundation can significantly reduce the value of your home. When selling your property, potential buyers may be deterred by the prospect of costly foundation repairs, leading to lower offers or extended time on the market.

Cost Savings

Addressing foundation cracks early is more cost-effective than waiting until the damage worsens. Timely repairs can prevent the need for extensive foundation replacement or reconstruction, saving you money in the long run.foundation-cracks-stablwall-2

Foundation cracks are a clear indication of underlying issues that, if left unattended, can have severe consequences for your home. From compromised structural integrity to water infiltration, mold growth, pest infestations, and reduced property value, the risks associated with foundation cracks are numerous and serious.

Immediate repair is not just advisable; it is essential for the safety, longevity, and value of your home. If you notice any cracks in your foundation, no matter how small they may seem, consult a professional foundation repair expert promptly. Addressing the issue at its earliest stages can spare you from more extensive and expensive repairs in the future, ensuring your home remains a safe and secure haven for you and your family.

  • Moisture
    For the most part, foundation cracks are the result of soil expansion or contraction, so moisture plays an important part in the strength and steadiness of your foundation. Maintain the right amount of moisture down there. If you stay in a region that has a lot of play when it comes to wetness and drying out, it will put a strain on the structure. You may need to get soakers and other water delivery mechanisms to make sure the levels are steady.

  • Trees
    Let’s be clear about this, trees are a necessity and most weather related problems can be attributed to not having enough of them, so we are not recommending you cut down every tree around your house. As long as trees get enough water, they are not going to suck it out from under your house. Get a qualified engineer or a specialist to come take a look at the tree and root problems that may or may not pose a threat to your foundation. When planting trees, plant them away from the main structure of the house. If the tree’s branches can touch your walls, it is too close.
  • Downspouts
    While you need to keep a certain level of moisture under the house, too much water is a bigger issue. Foundation cracks can appear in places where there are soil swells or runaways, both a result of too much water. You may want to get a simple diverter, something that will keep water from settling along the walls and cause wetness to settle in the basement.

Regular maintenance can go a long way in keeping your home foundation cracks free and will stand steady and last a lifetime.

What is Carbon Fiber and Why Should You Care? Houston, TX

Carbon Fiber is a man-made, super strong, lightweight material. Mass production of it has made it more affordable and more widely used across multiple industries.

In recent years, foundation repair contractors are using it in residential foundation repair applications.

Carbon fiber is super lightweight and comes in a woven fiber sheet. If you don’t know what carbon fiber is, at first glance it seems like a hoax. It doesn’t seem like this material would be able to repair your basement wall. But if you understand it is the same material used in airplanes and bullet proof vests it makes more sense.

Call Us! We can help! (866) 782-5955

Carbon fiber can also be melted down into a liquid and formed into liquid metal. So, instead of a sheet it can be molded into all sorts of items. If you hear about Kevlar helmets, vests or other safety equipment it is actually melted down and formed carbon fiber.

In a foundation repair application, carbon fiber is used in multiple ways. It can be used as staples to repair a structural crack. Carbon fiber staples are used with epoxy to create a rigid hold on a moving crack.

The other application is to use a carbon fiber sheet to fix a bowed concrete block wall. The carbon fiber needs to be tied to the framing of the house to secure the foundation to the newly stabilized foundation. Carbon fiber foundation repair is an alternative method to steel I-beams and wall anchors that are commonly used to fix a bowed block wall.

If you are getting a quote from a foundation repair contractor and they say they are going to use carbon fiber repair or carbon fiber staples to repair a crack, don’t be scared or skeptical. They are using a high-tech material that is stronger than steel.

House Foundation Cracks – Structural Problem or Water Problem

House Foundation Cracks

Are you dealing with house foundation cracks? These cracks can be caused either by structural or water problems. Determining the underlying cause of the cracks will help you apply the best possible solution when it comes to repair.

Structural vs. Water Cracks

If you have a poured concrete foundation, house foundation cracks will usually occur as a result of structural problems or water pressure acting on the foundation. You can determine what the cause of the cracks is by examining the cracks to determine their width and location on the foundation wall.

Non-structural cracks are no wider than an eighth of an inch. They are caused by lateral pressure acting on the foundation walls. They therefore occur mostly on the lower part of the foundation wall. These cracks may be dry when they are first observed. However, like most cracks in foundation walls, they will eventually begin to seep water when the level of ground water is high.

Structural cracks are usually wider than an eighth of an inch. They usually occur as a result of wall movement. Therefore, they are almost always on the upper corners of the wall or in the middle section and have a symmetrical pattern.

Repairing foundation cracks

Repairing non-structural cracks is usually easy. However, it still requires the services of a waterproofing professional to determine the underlying cause of the cracking. This has to be solved before the actual cracks are repaired.

Non-structural cracks can be repaired using epoxy or polyurethane injections. The sealing of the cracks with epoxy is great only if you want to hold the cracks in place. This is not advisable where there is minor foundation movement. Polyurethane would be a better sealer to use in these situations as it is more flexible when it settles.

Structural crack repair is a major job especially if movement of the wall is significant. Modern repair of these walls involves the use of carbon fiber strips. These can be placed to prevent further movement of the walls. In some cases, steel braces may be required. This will stabilize the wall and prevent further movement. They can be adjusted with time to help to eventually straighten the wall.

In cases where the wall has rotated more than two inches, only steel beams can be used. It is therefore important to discuss your needs with a contractor. This will help you identify the best solution for your wall.

Foundation Step Cracks – Why You Should Be Concerned

Foundation Step Cracks

Cracks are something that no homeowner ever wants to see in their walls. They especially never want to see them in their foundation walls. However, cracks do occur every once in a while. While some cracks are superficial resulting from the natural drying process, other cracks run deeper and are often a sign of a structural problem with the foundation.

It is important to be able to differentiate between structural and superficial cracks. This will let you know whether you should be concerned or not. It will also tell you when your foundation needs immediate attention.

Step Cracks

Masonry block foundations are built by stacking blocks on top of each other. The blocks are arranged in a staggered pattern to give the wall strength. Mortar is used between the blocks to form a bond.

Step cracks often appear on masonry foundation walls. Cracks occur along the weakest parts of the wall. When it comes to masonry block foundation walls, the weakest part is that between the blocks. This space consists of mortar that is used to bond the blocks together and form the wall. The appearance of these cracks is therefore a clear indication of foundation failure.

The cracks appear like stair steps. This is because they follow the spaces between the blocks.

Why Your Wall is Cracking

When you notice the cracks in your foundation, you may be wondering why they occurred in the first place. This type of cracks is an indication of foundation failure. This often occurs as a result of pressure acting against the wall from the exterior. When the pressure exceeds the resistance of the wall, the wall begins to bow inward. When it comes to a masonry block foundation wall, the bowing is first noticed as step cracks.

In some cases, the soil may be doing the opposite. It may not be providing adequate support for the foundation wall for example, during a drought when the soil shrinks away from the foundation wall. The wall bows outward due to a lack of support. The cracks form at the point of bowing.

What You Should Do

If you’ve noticed step cracks in your foundation wall, don’t attempt to repair the wall on your own. This is not a DIY job. It is a job that is dangerous and requires a great deal of skill and expertise to repair properly and safely. Get in touch with a basement repair professional with experience in dealing with bowing walls.

Common Misconceptions about Foundation Cracks

Foundation Cracks

If you’ve spotted some foundation cracks, you’re probably searching the internet for more information about them and what you should do. It is not uncommon to come across misleading information.

As a homeowner, you’re not expected to know or understand all the information about foundation cracks that you come across. However, it is important to verify this information. Taking action on misleading information can result in damage that could be even more expensive to repair.

The following are common misconceptions that you should avoid when it comes to the repair of cracks in foundations:

  • Cracks originate from problems that occurred when laying the foundation

Although some cracks are caused by problems that originated during the construction phase, some cracks are caused by problems that occur underneath the foundation. The condition of the soil that surrounds the foundation plays a major role in determining the health of the foundation. It is therefore important to ensure that this soil is healthy and able to support your foundation.

  • You can use hi-tech sealants to permanently fix cracks in foundations

Modern sealants made of polyurethane or epoxy are quite effective in sealing foundation cracks. They are strong and flexible. They do a great job for patchwork but aren’t a permanent solution for foundation cracks.

Cracks in the foundation are often a sign of a deeper problem. If the issue that caused the cracks in the first place is not addressed, then further damage to your foundation will occur. In some cases, the damage may be worse than the cracks you fixed with the sealant.

  • It’s better to replace a damaged foundation than to repair it

Unsuspecting homeowners may be tricked by unscrupulous contractors into replacing their foundations instead of repairing them. They are under the misguided notion that replacing, although more expensive, is a long lasting solution.

A truly experienced contractor will tell you that this isn’t always the best solution. As mentioned previously, it is important to determine the underlying cause of foundation damage before determining what solution to apply.

Replacing the damaged foundation may not always solve the problem. You’re just placing a new foundation that will likely suffer the same fate as the old one.

  • You can ignore small cracks in a concrete foundation

It is true that concrete cracks as it settles. However, small cracks in foundations can result in more serious problems as they allow water to seep through. Any and all foundation cracks ought to be inspected by a professional to ensure that the underlying cause is identified.
