Addressing a Failing Concrete Foundation

A strong foundation is vital for the stability and structural integrity of any building. However, over time, concrete foundations can develop issues that require immediate attention. In this article, we will explore the causes of a failing concrete foundation, how to diagnose the problems, available repair options, hiring professional contractors, preventive measures, cost considerations, and more.


A solid and stable foundation is crucial for any structure, as it bears the weight and provides support. A failing concrete foundation can lead to significant structural problems, compromising the safety of the building and its occupants. Recognizing the signs of a failing foundation is essential for early intervention and preventing further damage.

Understanding the Causes

Several factors can contribute to a failing concrete foundation. Understanding these causes can help homeowners and building owners take appropriate measures to address the issues.

Soil Movement and Settlement

One of the primary causes of foundation problems is soil movement and settlement. Expansive soils, such as clay, expand and contract with changes in moisture content, exerting pressure on the foundation walls. This constant movement can lead to cracks, uneven settling, and structural instability.

Poor Construction Practices

Inadequate construction practices during the initial foundation installation can also contribute to problems in the future. Insufficient compaction, improper reinforcement, or the use of low-quality materials can weaken the foundation, making it susceptible to failure.

Water-Related Issues

Water is a significant enemy of concrete foundations. Excessive water accumulation around the foundation can saturate the soil, causing it to expand and exert pressure on the walls. Poor drainage systems, leaky plumbing, or improper grading can all contribute to water-related foundation issues.

Diagnosing Foundation Problems

Identifying foundation problems early on is crucial for prompt repairs. Here are some methods to diagnose foundation issues:

Tree Roots and Vegetation

The growth of tree roots and vegetation near the foundation can have a detrimental effect. As roots expand, they can exert pressure on the foundation, leading to cracks and movement. Additionally, large trees can absorb significant amounts of moisture from the soil, causing it to shrink and potentially destabilize the foundation.

Visual Inspection

Performing a visual inspection of the foundation and surrounding areas can reveal several telltale signs of problems. Look out for cracks in the walls, floors, or ceilings, uneven floors and doors that stick or don’t close properly, as well as gaps between walls and windows or doors. These visible signs often indicate foundation movement or settlement.

Repair Options

When it comes to addressing a failing concrete foundation, several repair options are available. The choice depends on the extent of the damage and the underlying causes. Here are some common repair techniques:


Slabjacking, sometimes known as mudjacking, is a technique used to lift and level sunken concrete slabs. This method involves injecting polyurethane foam beneath the sunken slab, raising it back to its original position.

Foundation Settlement Measurements

Professional contractors can conduct precise measurements to assess the severity of foundation settlement. They use specialized tools to measure the vertical movement of specific points on the foundation, helping them determine the extent of the problem.

Consulting a Structural Engineer

In cases where the foundation issues are complex or severe, consulting a structural engineer is recommended. They possess the expertise to evaluate the structural integrity of the foundation and recommend suitable repair solutions.

Underpinning Techniques

Underpinning involves strengthening the foundation by extending its depth or breadth. This technique is suitable for foundations experiencing settlement or inadequate load-bearing capacity. Methods such as concrete piers, helical piers, or micro-piles can be used to underpin the foundation and provide additional support.

Installing Steel Piers

Steel piers are often used to stabilize foundations that have settled due to soil movement. These piers are driven deep into the ground until they reach stable soil layers, providing support and preventing further settlement.

Helical Pier Installation

Helical piers are similar to steel piers but have helical plates that help stabilize the foundation. They are screwed into the ground, providing resistance against vertical movement and offering a stable foundation support system.

Hiring Professional Contractors

Addressing foundation issues requires the expertise of professional contractors. Here are some essential steps to follow when hiring contractors for foundation repair:

Researching and Selecting Reputable Contractors

Take the time to research and identify reputable contractors specializing in foundation repairs. Look for companies with extensive experience, positive customer reviews, and appropriate certifications or memberships in professional organizations.

Requesting Quotes and Comparing Options

Contact multiple contractors and request detailed quotes for the proposed repairs. Compare the provided information, including the scope of work, materials, estimated timeline, and cost, to make an informed decision.

Verifying Licenses and Insurance

Ensure that the chosen contractors hold the necessary licenses and insurance coverage. This step helps protect you from potential liabilities and ensures that the work is carried out by qualified professionals.

Preventing Future Issues

Taking preventive measures can help mitigate the risk of future foundation problems. Here are some practices to consider:

Maintaining Consistent Moisture Levels

Maintain consistent moisture levels in the soil around the foundation. Avoid excessive watering near the foundation or allowing the soil to dry out excessively. Consistent moisture helps prevent soil expansion and contraction, reducing the strain on the foundation.

Proper Drainage and Landscaping

Ensure that the surrounding landscape slopes away from the foundation to prevent water from accumulating around it. Install proper drainage systems, such as downspout extensions and French drains, to redirect water away from the foundation.

Regular Foundation Inspections

Schedule regular inspections by professionals to identify any potential issues early on. These inspections can help detect minor problems before they escalate, saving you from extensive repairs in the future.

Cost Considerations

The cost of addressing a failing concrete foundation can vary depending on various factors. Some considerations include the extent of the damage, the chosen repair method, accessibility to the foundation, and any additional work required. While it’s challenging to provide an exact cost without assessing the specific situation, it’s important to budget for foundation repairs and consider the long-term savings associated with addressing the issue promptly.


A failing concrete foundation can pose serious risks to the stability and safety of a building. Recognizing the signs of foundation problems and taking timely action is crucial. By understanding the causes, diagnosing the issues, exploring repair options, hiring professional contractors, and implementing preventive measures, homeowners and building owners can address failing concrete foundations effectively. Remember to consult with experts and take necessary steps to maintain a strong foundation, ensuring the longevity and stability of your structure.


The duration of foundation repairs depends on the complexity and severity of the issue. Minor repairs may take a few hours, while extensive repairs can last several weeks. It’s best to consult with the contractor for a more accurate timeline.

In some cases, foundation repairs may be covered by insurance, particularly if the damage is a result of a covered peril, such as a plumbing leak or natural disaster. However, it’s important to review your insurance policy and consult with your provider to determine coverage.

Selling a house with foundation problems can be challenging, as it can affect the value and marketability of the property. It’s advisable to disclose any foundation issues to potential buyers and consider completing necessary repairs beforehand.

Foundation repairs require specialized knowledge and equipment. While there are some DIY solutions for minor issues, it’s generally recommended to seek professional help. Professional contractors have the expertise and experience to assess the problem accurately and provide effective solutions.

Regular foundation inspections are recommended, especially in areas prone to soil movement or where foundation issues are common. It’s advisable to have a professional inspection every few years or if you notice any signs of foundation problems.
