Foundation cracks let in air, moisture and pests. They also indicate a need for repair. There are many different long-term solutions. The methods used depend on the size of the problem, soil conditions and the type of foundation.
Cracks in foundation walls can occur for a variety of reasons. While some are harmless, others are a sign of serious structural problems that need to be addressed right away. It’s important to know how to identify and deal with these issues so that your home stays safe and sound for years to come.
Dry cracks – These are narrow, hairline-thin cracks that form when concrete loses moisture through evaporation. They often appear in the corners of a room or near doorways and windows, and may also have a musty odor and be accompanied by sagging floors. These cracks are not necessarily a cause for concern, but they should be monitored closely as they could grow larger over time.
Wet cracks – These appear much wider than dry cracks and are often accompanied by water infiltration. They are caused by soil movement and expansion when the clay surrounding a foundation absorbs excess moisture, which causes it to swell and push against the foundation walls. Wet foundation cracks can lead to serious damage if not treated quickly, so they should be fixed as soon as you notice them.
Isolated cracks – Cracks that occur in only one block in a concrete block wall are usually non-structural and don’t pose any serious issues, but they should still be monitored as they might get bigger over time. Cracks that run parallel to the ground and are wider than a hairline are a clear indication of a serious problem, as they indicate that a large portion of the foundation is sinking.
Widening gaps – These are a clear indication that the foundation has shifted and needs to be repaired, as they can lead to other problems such as bowing walls and water intrusion. If you see any gaping cracks, it’s essential to contact a professional for a inspection and evaluation of the situation so that a proper repair plan can be implemented.
If the cracks are found to be serious, a specialist will create a comprehensive repair plan that can involve anything from sealing minor cracks to installing piers for significant support. The specialist will evaluate the condition of your foundation and soil, as well as other signs such as sagging floors or sticking doors, to determine what the best course of action is for the repair and prevention of future damage.
Water Damage
Water damage is a common problem, and one that isn’t always easy to spot. But you should be vigilant for signs of moisture that can signal serious issues with your foundation. Moisture infiltrating the concrete of your foundation can erode it over time, creating weak areas that will eventually crack and bow. It can also rot wood that supports the foundation, leading to collapse.
Thankfully, you can prevent or repair damage from water infiltration by addressing the underlying cause. Leaky pipes, improper grading, and poor drainage can all lead to excess moisture around your home’s foundation.
When builders construct homes, they take into account average rainfall and soil conditions for the area. But sometimes, extreme weather can alter those conditions. Heavy rains or floods can wash away soil that surrounds your foundation, causing it to swell and apply pressure against the walls. This is known as hydrostatic pressure and can cause foundation cracks.
Water that seeps into the walls of your basement or crawl space can also contaminate the air, leading to mildew or mold growth. It can also corrode metal components in the foundation, making it a risk to your home’s safety and structural integrity.
You can check for signs of water damage in your foundation by looking for lines or stains on the wall surfaces, mold or mildew, and efflorescence (a white powdery substance that appears on the surface of concrete walls). Regular inspections should also be conducted after major storms to catch problems early.
A professional can inspect your foundation for signs of dampness and recommend the best course of action. Depending on the severity of the problem, they may recommend a sump pump or french drain system to remove water from your property and direct it away from the foundation. They can also seal any cracks that appear with specialized epoxies and waterproof sealants. They can also install drains to prevent water from entering your crawl spaces or basement, preventing water from absorbing into the soil and pushing against foundation walls. This can prevent future cracking and help maintain your home’s value.
Structural Issues
Structural issues, like cracks that widen, leaning walls, and sagging floors, are often the result of foundation movement due to soil conditions. Expansive soil, poor drainage, erosion, and inadequate site preparation can all contribute to shifting and weakening a building’s base, which can lead to serious structural problems over time. Recognizing these issues early and addressing them quickly prevents them from causing worse damage and requiring costly repairs.
In addition to horizontal and diagonal cracks, other signs that your foundation needs repair include gaps between the floor and walls, sticking windows and doors, and sagging or bowing walls. When these signs occur together, they can indicate a much more severe issue that requires immediate attention.
Settling and heaving, which is common in many areas of Southern California and Arizona, can cause uneven settlement throughout your home. This can affect the internal framing of your house, which in turn places new stressors on your foundation. These stressors can make your floor and wall cracks, but they also can cause the skewing of internal framing that makes it difficult for windows to open and close and doors to fit properly.
The best way to identify a structural issue is to consult with an expert. A Dalinghaus Construction professional can provide a visual inspection of your home’s foundation and recommend the best course of action for repairing it. We have access to advanced tools and methods, like laser leveling, that enable us to identify and address structural problems before they become serious and expensive to repair.
Bowing walls, for instance, are a clear sign that the structural integrity of your foundation has been compromised. If the problem goes unchecked, it can eventually lead to severe structural damage or even a complete building collapse. When a wall begins to bow, experts evaluate and measure its severity, then determine the most appropriate stabilization method based on your home’s unique situation. For example, if the bowing is minor, high-strength carbon fiber straps can be bonded to the wall to prevent further movement without invasive construction. For more significant bowing, steel I-beams are installed vertically along the wall to support it.
Underpinning
When the foundation of a home or commercial structure is under threat, it’s important to seek professional help. Various underpinning methods are available to repair structural damage and stabilize existing foundations, depending on the type of building, soil conditions, and other factors. These methods are a cost-effective way to improve stability, and they prevent further damage from occurring.
Some signs that a foundation needs underpinning include cracks in the walls or floors, doors and windows that don’t close properly, or uneven floors. Often, these problems are caused by the foundation shifting and sinking as a result of the weight of the structure or changes to load-bearing structures.
The first step to underpinning a foundation is to create a repair plan that pinpoints where supports need to be placed. Most often, these supports are needed along the perimeter of the building, where the foundation has shifted or sunk. However, in 10% of cases, supports may also be needed under the middle of the building.
Once a plan is in place, the next step is to install the supports. There are two main types of underpinning solutions: piers and pilings.
Piers are a common choice for underpinning homes and commercial buildings. They are long steel piers that are driven into the ground under the foundation. These piers are then supported by load-bearing competent soil, acting as underground stilts to keep the foundation secure against settlement.
Other underpinning methods involve excavating and adding new footings beneath the existing ones to extend their reach into more stable soil layers or bedrock. This is a more costly option, but it can be effective in some situations.
In some cases, the best way to underpin a foundation is by installing wall anchors. These are like large bolts that can be tightened to slowly straighten the foundation walls and strengthen them. This method is typically used in cases where the foundation wall has bowed significantly, which can’t be fixed by other underpinning techniques. This is a major job that requires extensive excavation and construction, but it can be very effective.
