7 Common Signs Your Concrete Needs Lifting or Leveling Services

June 25, 2024
Concrete’s remarkable strength and durability have made it a popular material for building homes over the years. It is essential to remember that concrete structures are still susceptible to the effects of time and different environmental factors. A number of variables, including soil displacement, moisture infiltration, weather patterns, and chemical reactions, can affect the long-term structural integrity of the concrete in your home. Even though these conditions might not affect concrete right away, over time, it might show symptoms of distress like settling, sinking, and crack formation.
When it comes to solving different concrete issues without having to completely rebuild the structure, concrete leveling is a very useful solution. This procedure entails adding more concrete to the concrete structure or using techniques like polyjacking or mudjacking to successfully address the problem. In this blog, we’ll look at the main warning signs that your house might need concrete leveling.

Signs Your Home Needs Concrete Leveling

1. Visible Cracks in Concrete

Concrete, though renowned for its strength and durability, is not impervious to the relentless forces of nature and time. As concrete cures and ages, it is susceptible to the formation of cracks, which can serve as harbingers of deeper-seated problems. These cracks may initially manifest as faint hairline fractures, barely perceptible to the untrained eye, or as more conspicuous fissures that threaten the integrity of the structure.
Understanding the different types of cracks is essential for accurate diagnosis and appropriate remediation. Hairline cracks, while seemingly benign, can widen over time, allowing moisture ingress and exacerbating structural deterioration. In contrast, larger fissures may indicate significant shifts or settlements within the concrete, necessitating prompt intervention to prevent further damage.

2. Uneven or Sunken Concrete

The emergence of uneven or sunken concrete surfaces can be a cause for concern, signaling potential deficiencies in installation, compaction, or subgrade support. Commonly observed in driveways, sidewalks, and patios, these irregularities not only detract from the aesthetic appeal of a property but also pose significant safety hazards to pedestrians and vehicles alike.
Identifying the telltale signs of uneven concrete requires a keen eye for detail. Look for areas where the surface appears to tilt or dip, creating tripping hazards and impeding drainage. Addressing these issues promptly can prevent further settlement and mitigate the risk of costly repairs down the line.

3. Water Pooling and Drainage Problems

Water pooling on concrete surfaces is not merely a nuisance; it is a precursor to potential structural degradation. Prolonged exposure to moisture can compromise the integrity of the concrete, leading to erosion, cracking, and spalling. Identifying the signs of poor drainage, such as standing water after rainfall or discoloration on the surface, is paramount for preserving the longevity of concrete structures.
Proper drainage design and maintenance are critical for mitigating these risks and safeguarding against water-related damage. Implementing measures such as installing french drains, grading the terrain away from the structure, and sealing concrete surfaces can help prevent moisture infiltration and extend the lifespan of your concrete infrastructure.

4. Doors and Windows Misalignment

Shifts in the underlying concrete can reverberate throughout a structure, manifesting as misaligned doors and windows. Difficulty in opening or closing doors, as well as visible gaps between frames and walls, are common indicators of underlying concrete settlement or movement.
Addressing these misalignments promptly is essential to prevent further structural damage and maintain the functionality of doors and windows. Consultation with a qualified contractor or structural engineer can help identify the root cause of the misalignment and implement appropriate remedial measures to restore stability and alignment.

5. Gaps Between Concrete and Structures

Gaps between concrete slabs and adjacent structures can serve as conduits for moisture infiltration, pest ingress, and thermal bridging, compromising both the integrity of the concrete and the structural envelope. These gaps, often caused by settlement, expansion, or contraction, require vigilant inspection and timely intervention to prevent further deterioration.
Common sources of concrete gaps include inadequate joint sealing, differential settlement, and thermal expansion and contraction. Addressing these issues may involve resealing joints, installing expansion joints, or implementing waterproofing measures to mitigate moisture intrusion and preserve the integrity of the concrete and surrounding structures.

6. Sinking Concrete Steps or Stoops

Sinking steps or stoops not only detract from the aesthetic appeal of a property but also pose significant safety hazards to occupants and visitors. Soil erosion, inadequate support, or structural deficiencies can cause these elements to settle unevenly, creating tripping hazards and compromising accessibility.
Timely intervention is imperative to address sinking steps or stoops and prevent further settlement. Remedial measures may include underpinning the foundation, stabilizing the subgrade, or replacing the affected concrete elements to restore stability and functionality safely.

7. Sloping or Sagging Floors

Sloping or sagging floors within a home can indicate underlying foundation problems, often linked to concrete settlement or structural shifts. These structural anomalies not only compromise the aesthetic appeal of the interior but also pose significant risks to occupant safety and comfort.
Identifying the signs of floor sloping, such as visible cracks in walls or ceilings, uneven transitions between rooms, or doors that no longer close properly, is essential for accurate diagnosis and timely intervention. Consultation with a qualified structural engineer or foundation specialist can help identify the underlying cause of floor sloping and implement appropriate remedial measures to stabilize the structure and restore the integrity of the interior space.


Vigilance is key to preserving the integrity and longevity of concrete structures. By recognizing the early signs of concrete troubles and addressing them promptly, you can mitigate the risk of costly repairs and ensure the safety, functionality, and aesthetic appeal of their properties for years to come.
