Common Foundation Cracks: When To Worry And How To Fix Them

Overview: What Are The Different Types Of Foundation Cracks?

Foundation cracks can be concerning and even costly if not properly addressed. It is important to understand the different types of foundation cracks and when they should be a cause for worry.

Horizontal, vertical, stair-step, and diagonal are the four most common types of foundation cracks. Horizontal cracks indicate that there is likely an issue with the overall structure or integrity of the foundation itself.

Vertical cracks can be caused by settling or shrinkage due to changing temperatures; however, these are generally less concerning than horizontal ones. Stair-step cracks are often a sign that there may be an issue with your home’s drainage system since water is likely escaping from outside the house and seeping into the foundation.

Finally, diagonal cracks are often caused by movement in the soil under the foundations due to changes in moisture levels or improper compaction during construction. Knowing these different types of foundation cracks can help you determine when it's time to call a professional and have them inspect your foundation for any potential issues.

Causes Of Foundation Cracks In New Houses

Foundation cracks in new houses can be caused by a number of factors, including soil type, moisture levels, and the size and shape of the foundation. When a foundation is built on clay or sandy soils that are not packed properly or are not able to support the weight of the house, cracking can occur.

If there is too much moisture in the soil, it can cause expansive soils to expand and contract which leads to cracks. Additionally, if the foundation is made from concrete blocks or has large horizontal joints between them that are not filled with mortar, it can cause cracks as well.

Finally, if the shape of the foundation does not allow for evenly distributed load bearing capacity across its surface, cracking may also occur due to excessive stress. All of these factors should be considered when building a new house so that any potential problems with the foundation can be avoided.

Strategies To Avoid Potential Foundation Issues

Good foundation maintenance is key to preventing serious issues down the line. Start by addressing any drainage problems in your yard, as these can cause excessive moisture around the foundation, which can lead to cracking and other damage.

Make sure gutters are in good condition and that they direct water away from your home. Additionally, check for plumbing or irrigation leaks both inside and outside of your home; if you find any, have them repaired promptly to avoid further damage.

If you live in an area with expansive clay soils, consider using soil treatments that reduce soil expansion and contraction. Finally, make sure all landscaping is kept at least six inches away from the foundation of your home to keep it from shifting and potentially causing cracks.

With a little bit of preventative maintenance, you can help avoid potential foundation issues before they start.

Different Types Of Foundations And Materials Used

There are a variety of foundations and materials used in home construction. Concrete is the most common type of foundation, and it can be poured in various shapes and sizes.

Block foundations, made of concrete blocks or cinder blocks, are also popular for homes. Brick foundations are more traditional but still strong and durable.

Wooden foundations are not as common anymore, but can be found in some older homes. Each type of foundation has its own set of potential problems and should be inspected regularly for signs of cracking or other damage.

It is important to know how to identify common foundation cracks and when to call a professional for help.

Signs Of Serious Foundation Trouble Apart From Cracking

When it comes to foundation issues, cracking is often the first sign of trouble. However, there are other signs of serious foundation problems apart from cracking that homeowners should be aware of.

These include doors and windows not opening or closing properly, walls bowing or leaning, floors becoming uneven, chimneys pulling away from the house, water collecting near the foundation, and basement walls sweating. If any of these symptoms occur in combination with cracking in your home’s foundation, you should take action immediately as this could be a sign of a more severe problem.

It is important to contact a professional to inspect your foundation and determine the best course of action for fixing it.

Identifying Indicators Of Foundation Problems

Identifying indicators of foundation problems can be difficult for homeowners, as many issues can appear to be minor at first. It is important to know when the cracks in your foundation are cause for concern and when you should call a professional.

Common signs that something is wrong with your foundation include large cracks, uneven floors, and doors or windows that no longer close properly. If you notice any of these signs, it is important to take action right away.

Foundation repairs can be expensive and time-consuming if not done in a timely manner. Inspecting the exterior of your home is also essential for detecting foundation issues before they worsen, as it will help you identify any significant displacement of soil or water damage around the structure's perimeter.

Having a professional inspect your home regularly is the best way to ensure that any potential problems are caught early on and addressed quickly.

Detection Of Structural And Non-structural Foundation Cracks

Cracks in the foundation of your home can be a cause for worry, but not all cracks are structural. Structural cracks are caused by shifts in the foundation, while non-structural cracks are from settling and drying shrinkage.

The difference between the two is important to understand when determining if you need to call a professional to make repairs. It's possible to detect structural and non-structural foundation cracks by looking for specific patterns and characteristics.

Non-structural cracks usually appear in a stair-step pattern, with each step getting wider as it moves away from the center of the wall. These types of cracks rarely have an impact on the integrity of your home's structure and can generally be fixed with minor repair work such as caulking or sealing.

On the other hand, structural cracks typically run at an angle or form long diagonal lines across walls or floors. If you see any vertical or horizontal cracking, you may need to hire a professional who specializes in foundation repair in order to ensure that your home is safe from potential damage.

Knowing how to detect different types of foundation cracks can help homeowners determine when they should worry and how best to fix them.

Evaluation Methods For Major Concrete Slab Cracks

Evaluating major concrete slab cracks for repair or replacement is an important part of home maintenance. The most common type of crack in a concrete foundation is a shrinkage crack, which typically occurs when the concrete cures and shrinks during the drying process.

These are often thin, spider-web like cracks that appear on the surface of the concrete slab and can be easily fixed with a crack filler product. Other types of cracks include settlement cracks, caused by shifting soil beneath the slab, and structural cracks, which occur due to excessive weight on the slab or due to improper construction techniques.

To determine if repairs are needed, homeowners should inspect their foundation for signs of movement or separation between sections. If there are large gaps between slabs or if one section appears to be leaning away from another, it may indicate that further investigation is necessary.

In addition to visual inspections, moisture testing can help detect any water infiltration, which can contribute to deterioration and further cracking. Professional engineers may also use ground-penetrating radar or other sophisticated methods to inspect subsurface conditions and determine whether there has been significant settling or movement in the area of concern.

How To Examine Foundation Wall Cracks

Inspecting foundation wall cracks is an important part of maintaining the integrity of a home. To properly assess the situation, be sure to look for vertical, diagonal, or horizontal cracks.

Additionally, check if the crack appears to be growing wider over time. When examining a crack it is also important to determine if there are any signs of water damage such as staining or mildew growth around the crack.

If there is water damage present this could indicate that the wall has been compromised by moisture and should be addressed immediately. Other factors to consider when inspecting a foundation wall include investigating if the crack is located near windows or doors, determining what type of material was used in constructing the foundation wall, and checking for any other visible signs of structural weakness such as bulging walls or sagging floors.

Taking note of all these details can help determine whether further action needs to be taken or not.

Assessing Damage Caused By Minor Concrete Slab Cracks

Assessing damage caused by minor concrete slab cracks can be a difficult task as the cracks may appear small and insignificant, but could lead to larger issues. A common foundation crack can often appear in a variety of shapes and sizes, ranging from hairline fractures to diagonal or stair-step patterns.

To determine if a crack is worth worrying about, it is important to look at its size and shape, as well as any other structural damage that may have been caused. If the crack is wider than 1/4 inch it should be monitored for further development and addressed if necessary.

Additionally, examination of the surrounding walls and floors should take place to determine whether there has been any shifting or movement that could indicate a more serious issue. In order to fix a common foundation crack, a homeowner or professional must first assess the cause before taking action such as repairing the underlying structure or using an epoxy injection system.

It is recommended to hire an experienced contractor who specializes in these types of repairs for best results. Repairs may involve anything from reinforcing weakened beams or columns to replacing damaged floor joists or supporting walls.

It's important to address minor concrete slab cracks quickly before they become major problems.

Investigating Factors That Lead To Foundations Failing

Investigation into the causes of foundation failure is critically important for the construction industry, as it can determine why certain structures are more prone to cracking than others. It is important to understand what type of soil the foundation was built on, whether there were any changes in moisture levels or weather, and if any repairs have been made over time.

Other factors that can lead to a failing foundation include excessive weight on the building, poor drainage around the structure, and improper installation of footings and beams. These issues should all be considered when assessing a potential foundation failure.

Additionally, it is essential to consider how quickly any cracks appear and how far they extend, as these can give clues as to what type of damage has occurred. Finally, if necessary, experts should be consulted in order to properly assess the situation and provide advice on the best methods for repair.

Prevention Of Foundation Cracks In New Homes


When building a new home, it’s important to take measures to prevent common foundation cracks from occurring. A good start is to have the soil and foundation inspected by professionals before any construction begins.

It’s also essential to use quality materials for the foundation and ensure that it is properly constructed. Any potential problems with the soil should be addressed as soon as possible, such as drainage issues or unstable ground.

During construction, care should be taken to avoid excessive vibration or weight on the area around the foundation, which can cause cracking. Additionally, it’s important to seal any cracks in concrete walls or floors that may appear while new home is being built.

These simple steps will go a long way in helping to prevent foundation cracks from forming and lessen the need for costly repairs down the road.

Remedies For Non-structural Cracks In Foundations

When it comes to non-structural cracks in foundations, homeowners should not worry too much. Most of these cracks are caused by settling or shrinkage of the concrete and do not indicate any serious structural problems.

However, if they become larger than a quarter inch wide, then you may need to take action. The most common remedies for non-structural foundation cracks include sealing them with caulk or epoxy, filling them with hydraulic cement, and waterproofing the area around the crack.

Sealing is often the best option for minor cracks as it will stop water from entering the crack and causing further damage. For larger cracks that can’t be sealed easily, filling with hydraulic cement is a good option because it will not only fill in the crack, but also prevent water from seeping in.

Lastly, waterproofing is an important step to prevent future cracking because it creates an impermeable barrier on top of the foundation wall which helps protect against water damage.

Treatment Options For Structural Foundation Cracks


Treating structural foundation cracks is an important part of maintaining the integrity and safety of a home or building. Depending on the severity of the crack, a variety of repair methods can be used to fix it.

One option is wall anchors and helical piers, which are used to stabilize the foundation and prevent further movement. Polyurethane foam injection is another solution, which involves injecting a resin-based foam into the crack to create a watertight seal that won't weaken over time.

For more severe cracks, carbon fiber straps may be necessary to strengthen and reinforce the foundation against damage from shifting soil. In some cases, underpinning may be required if the issue is linked to sinking or settling soil beneath the foundation.

This can involve installing new footings or pilings under the existing foundation in order to provide it with better support. Ultimately, treating structural foundation cracks requires careful analysis from an experienced professional who is knowledgeable about these types of repairs in order to determine what solution will work best for your situation.

Are Cracks Normal In New Foundations?

Cracks in new foundations are common and usually nothing to worry about. Most of the time, they are caused by the natural settling process that occurs as a house settles into its foundation.

They may also be caused by poor workmanship or inadequate construction materials. Generally, these types of cracks do not pose any structural concerns and can easily be fixed with some simple repair methods.

However, if the cracks appear to be worsening, it is important to have them evaluated by a professional contractor to ensure there are no structural problems with your foundation. Cracks should never be ignored as they could indicate a more serious problem with your foundation that may require more extensive repairs.

If you notice any signs of cracking in your new foundation, contact a professional immediately so they can inspect the damage and provide solutions for fixing it.

Why Is My New Foundation Cracking?

New foundation cracks can be alarming, but understanding the causes, prevention and repair of common foundation cracks can help you decide when to worry, and how to fix them. Foundations are designed to last for many years, but they can still be susceptible to settlement issues, soil movement and temperature changes.

When these occur, your foundation can experience cracking which is usually nothing more than a cosmetic issue. However, if you notice larger or multiple cracks in your new foundation, it could be an indication of a more serious problem such as structural damage.

In this case it is important to have an expert inspect the area and determine the severity of the damage before attempting any repairs. Prevention is always better than cure so there are several steps homeowners can take to reduce the risk of foundation cracking.

These include regularly monitoring soil moisture levels around the home, ensuring adequate drainage away from the house, and avoiding planting trees or shrubs too close to your home’s foundation walls. If you do find cracks in your new foundation wall or floor slab don’t fret; most surface level cracks can easily be repaired using products that adhere directly to the affected area and fill in any gaps.

Repairing common foundation cracks on time helps ensure that your home remains structurally sound for many years to come.

When Should I Worry About Foundation Cracks?

Cracks in the foundation of a home can be worrisome, but it is important to know when to worry and when not to. While some cracks are minor and harmless, others can indicate more serious issues with the foundation.

The amount of movement or activity in the area around the crack is an important indicator. Minor settling cracks may appear due to normal aging of the home, typically less than 1/8th of an inch wide, and do not require repair.

If there is evidence that the crack has grown over time, however, it may point to foundation settlement or shifting soil caused by water or other environmental factors. Cracks greater than 1/4 inch wide should be inspected by a professional for further evaluation and assessment.

If the foundation is severely compromised, repairs will need to be done before additional damage occurs. Generally speaking, when you notice a crack in your foundation, it’s best to get it checked out as soon as possible in order to prevent further damage from occurring.
