What is Spalling Concrete?
Spalling concrete occurs when the surface layer of your concrete deteriorates, leading to unsightly cracks and exposing the steel reinforcements beneath. This can weaken your structure and create potential hazards. Our spalling concrete repair service addresses this issue, restoring both the structural integrity and visual appeal of your property.
Why Does Concrete Spall?
Several factors contribute to spalling concrete:
- Moisture Ingress: Water penetration causes steel reinforcements to rust and expand, leading to concrete breakdown. This often results in ceiling leakage.
- Poor Construction Practices: Inadequate concrete coverage or low-quality materials can compromise structural integrity.
- Thermal Stress: Temperature fluctuations cause concrete to expand and contract, leading to stress and surface damage.
How to Spot Concrete Slabs with Spalling Issues
Noticeable cracks or flaking on the concrete surface often indicate the beginning of spalling. These are signs that the concrete is weakening and may be susceptible to further damage. Pay close attention to areas with high traffic or exposure to the elements.
If you can see the steel reinforcements within the concrete slab, it’s a clear sign of deterioration due to spalling. This exposed steel is vulnerable to corrosion, which can worsen the problem and lead to more extensive damage.
Spalling concrete often results in uneven or crumbling edges, particularly in areas subject to heavy loads or environmental stress. These areas are more likely to break away, posing potential safety hazards.
Rust stains on the concrete surface or moisture marks are telltale signs of water penetration, a major cause of spalling concrete. Address these issues promptly to prevent further damage and costly repairs.
If you tap the surface of the concrete slab and hear a hollow sound, it suggests that the concrete underneath has started to deteriorate and break away. This is a strong indication of spalling and requires immediate attention.

Spalling Concrete Prevention
Preventing spalling concrete requires proactive measures:
- Water Sealant: Use a high-quality water sealant to prevent water infiltration.
- Regular Painting: Regular painting helps maintain surfaces and prevents carbonation, a contributor to spalling.
- Crack and Hole Repair: Repair cracks and holes to prevent moisture and carbon dioxide penetration.
- Seal Drilled Holes: Seal any unused drilled holes to prevent water entry.
- Ventilation: Ensure proper ventilation in moisture-prone areas to reduce humidity and prevent carbonation.
Spalling Concrete Repair: 5 Steps to Restore Your Structure
1. Inspection and Assessment
Our experienced spalling concrete contractor begins by conducting a thorough inspection to assess the extent of the damage. This includes identifying areas with visible cracks, flaking, exposed reinforcements, and other signs of spalling concrete. We also evaluate the structural integrity of the affected area to determine if any additional reinforcement or replacement is necessary. This detailed assessment allows us to develop a tailored repair plan that addresses the specific needs of your structure.2. Surface Preparation
Proper surface preparation is essential for achieving durable and effective spalling concrete repair. We meticulously clean the damaged concrete surface, removing dirt, debris, loose concrete, and any contaminants that may hinder the bonding of repair materials. This often involves using mechanical tools like grinders or chisels to expose the healthy concrete and reinforcement bars beneath the damaged areas.3. Rust and Corrosion Treatment
If the spalling concrete has exposed steel reinforcements, we take steps to prevent further rust and corrosion. This involves treating the exposed steel with anti-corrosion agents to inhibit further deterioration. In cases of severe corrosion, where the reinforcement bars are significantly compromised, we may need to replace them entirely to ensure the long-term structural integrity of the repair.4. Application of Repair Materials
Once the surface is prepared and any corrosion is addressed, we apply high-strength repair materials to restore the damaged concrete. This may involve using specialized repair mortar or epoxy-based compounds, depending on the specific needs of the repair. These materials are carefully selected to ensure superior adhesion, durability, and compatibility with the existing concrete. We meticulously fill the damaged areas, restoring the structural integrity of the concrete slab and ensuring a long-lasting repair.5. Finishing and Curing
After applying the repair materials, we ensure a smooth and seamless finish that blends with the surrounding concrete. This involves carefully smoothing and blending the repaired area to achieve a uniform appearance. Proper curing is essential for maximizing the strength and durability of the repair. We follow industry best practices for curing, ensuring that the repair material bonds effectively with the existing concrete and achieves its optimal performance. This meticulous finishing and curing process prevents future spalling issues and ensures a visually appealing result.Concrete Roof Waterproofing

What WE Have Done
Frequently Asked Questions about Spalling Concrete
What causes spalling concrete?
Spalling concrete is primarily caused by moisture penetration, leading to the corrosion of embedded steel reinforcements. As the steel rusts and expands, it exerts pressure on the surrounding concrete, causing it to crack and break away. Other contributing factors include poor construction practices, thermal stress from temperature fluctuations, and exposure to harsh chemicals.
How do I know if I have spalling concrete?
Look for signs such as surface cracks, flaking, exposed steel reinforcements, uneven or crumbling edges, rust stains, and hollow sounds when tapping the concrete. If you notice any of these signs, it’s crucial to address the issue promptly to prevent further damage and potential safety hazards.
Can I repair spalling concrete myself?
While minor spalling concrete repairs may seem manageable, it’s generally recommended to hire a professional spalling concrete contractor. They have the expertise, tools, and knowledge to accurately assess the damage, prepare the surface correctly, and apply the appropriate repair materials for long-lasting results.
How much does spalling concrete repair cost?
The cost of spalling concrete repair varies depending on the extent of the damage, the location and accessibility of the affected area, and the type of repair materials required. It’s best to contact a spalling concrete repair specialist for a thorough inspection and a detailed quote based on your specific needs.
How can I prevent spalling concrete in the future?
Preventing spalling concrete involves proactive measures such as applying a high-quality water sealant to prevent moisture penetration, regularly inspecting and maintaining concrete surfaces, promptly repairing any cracks or damage, and ensuring proper ventilation in moisture-prone areas.
