CONCRETE SPALLING REPAIRS
Confirma™ delivers innovative, minimally disruptive, and long-lasting repair solutions to address even the most challenging spalling issues in commercial and industrial projects.
Concrete spalling is the process where the surface layer of concrete becomes damaged. Common signs include flaking, peeling or breaking away of the concrete. It typically manifests as crumbling or pitted areas and can range in severity from early signs like small cracks to severe structural issues. If left untreated, spalled concrete can begin to compromise the integrity of concrete structures, making timely intervention critical.
Why Concrete Spalling is a Concern
Structural Integrity:
In severe cases, spalling can compromise the structural strength of the concrete, especially if it exposes or damages the reinforcing steel. This can lead to further corrosion and weaken load-bearing components.
Safety Hazard:
Aesthetic and Functional Issues:
Spalled concrete looks unsightly and can allow water ingress, accelerating further problems and necessitating more extensive repairs if left unaddressed.
Causes of Concrete Spalling
Concrete spalling can result from several factors, including poor construction, reinforcement corrosion and environmental factors.
Reinforcement Corrosion:
Water, oxygen and chlorides (often from de-icing salts or seawater) penetrate the concrete, reaching the steel reinforcement. Low-quality, porous concrete is more vulnerable to water ingress and surface failure.
Corrosion expands the steel, causing internal pressure that leads to concrete spalling.
Freeze-Thaw Cycles:
Water inside the concrete freezes and expands, creating stress that leads to cracking and surface spalling over repeated cycles.
Poor Construction Practices:
Insufficient concrete cover over the reinforcement.
Low-quality concrete mixture or improper curing processes, leading to inadequate concrete thickness and reduced durability.
Improper placement or curing of fresh concrete can lead to weak surfaces that are prone to spalling.
Chemical Exposure:
Acids, sulphates or other aggressive chemicals degrade the concrete's surface over time.
Spalling can also be caused by alkali-silica reaction, a chemical reaction between cement paste and reactive aggregates.
Overloading or Impact:
Heavy loads or mechanical damage can cause spalling, especially in concrete floor slabs or structures not designed to handle such stresses.
Confirma™’s Approach to Spalling Repair
Confirma™ specialises in innovative, minimally disruptive solutions for commercial-scale concrete repairs, including addressing concrete spalling. Our methods prioritise:
- Restoring structural integrity while preventing further damage.
- Preventing concrete spalling through advanced protective measures.
- Minimising downtime for businesses by avoiding large-scale excavations.
- Using durable repair techniques with a lifespan of 30–50 years, ensuring long-term reliability.
The Confirma™ Repair Process
1. Comprehensive Inspection:
2. Surface Preparation:
Damaged or loose concrete is carefully removed to expose the sound substrate and remove the affected area. Proper surface preparation is essential to ensure the durability and adhesion of repair materials.
3. Reinforcement Treatment:
Corroded steel bars are cleaned, repaired or replaced to prevent further corrosion. Protective coatings may also be applied to enhance durability.
4. Application of Repair Material:
Using high-quality concrete repair materials and mortars, we rebuild the damaged areas. The concrete mixture is formulated to restore the concrete to its original condition, while optimising for strength and maximising the structure’s longevity.
5. Waterproofing and Sealing:
To prevent future spalling resulting from water damage, we apply advanced waterproofing and protective coatings. These layers safeguard the structure against moisture ingress, freeze-thaw cycles and chemical exposure.

Frequently Asked Questions
What is concrete spalling?
Concrete spalling is when the surface of concrete flakes, chips, or crumbles, often due to moisture, corrosion of internal steel, or weather damage.
How can spalling concrete impact industrial operations?
Spalling concrete can have significant consequences for industrial facilities, including:
- Safety hazards: Uneven or damaged surfaces increase the risk of trips, falls and machinery accidents.
- Structural integrity issues: Prolonged spalling can weaken the overall structure, compromising load-bearing capacity.
- Operational disruptions: Damaged concrete can hinder the movement of machinery and personnel, leading to delays and reduced efficiency.
- Increased maintenance costs: Ignoring spalling can lead to more extensive damage over time, resulting in higher concrete repair costs and potential downtime for complete replacements.
Addressing spalling promptly is essential to maintain safety, efficiency and cost-effectiveness in industrial environments.
What solutions does Confirma™ provide for repairing spalling concrete?
Confirma™ offers comprehensive solutions for how to repair concrete spalling and has the expertise to meet the unique demands of heavy industries:
Epoxy injection: For deeply cracked concrete, we use an advanced concrete crack injection technique, whereby a special epoxy is fed into deep cracks to restore the concrete’s structural integrity.
Surface repair and overlays: We apply high-performance overlays or resurfacing materials over the existing concrete’s damaged surface to provide a durable, smooth finish.
Corrosion protection: Our concrete repair processes include the application of anti-corrosion coatings and treatments to reinforce steel and prevent further deterioration.
Long-term durability: All our concrete spalling repair methods are designed to extend the lifespan of concrete slabs, ensuring they withstand the harsh conditions of industrial environments.
By choosing Confirma™, you’re investing in reliable, cost-effective repairs that minimise disruptions and safeguard the integrity of your operations.
Is spalled concrete repair the same as concrete cancer repairs?
No, but they’re closely related. Concrete spalling refers to the flaking, cracking, or chipping of a concrete surface, often caused by moisture, high alkalinity, freeze–thaw damage or poor workmanship. Spalling often affects only the top layer but may signal deeper issues.
Concrete cancer is a more serious condition where the steel reinforcement inside the concrete corrodes. As the steel rusts and expands, it forces the surrounding concrete to crack and break apart, appearing on the surface as spalling and rust stains.
In short: not all spalling is concrete cancer, but concrete cancer always causes spalling. Because it compromises structural integrity, concrete cancer repairs are more invasive and costly than more basic cement spalling repair options.
