Protecting Strata Buildings from Concrete Spalling & Concrete Cancer

This silent menace can wreak havoc if left unchecked, escalating into significant structural damage. Join us as we explore why it’s imperative to address concrete spalling early on to prevent its spread and safeguard your building’s longevity.


Understanding Concrete Spalling: Concrete spalling occurs when the outer layers of concrete deteriorate, resulting in chipping, cracking, or flaking. In strata buildings, where concrete is a primary construction material, spalling poses a serious threat. Factors such as weathering, poor construction practices, moisture ingress, and chloride ion penetration can accelerate this process, especially in coastal areas like Sydney.

The Importance of Early Intervention:

  1. Prevention of Escalation: Spalling, if left untreated, can spread rapidly, compromising the structural integrity of the building. What may start as a minor cosmetic issue can quickly escalate into a safety hazard, endangering residents and devaluing the property.

  2. Cost-Effective Maintenance: Early detection and treatment of spalling are far more cost-effective than addressing extensive damage later on. Timely repairs mitigate the need for costly reconstruction, saving strata owners and committees significant financial resources in the long run.

  3. Preservation of Aesthetic Appeal: Beyond structural concerns, spalling detracts from the visual appeal of the building, affecting its market value and curb appeal. Proactive maintenance not only ensures safety but also upholds the aesthetic standards expected in strata communities.

Treatment Options:

  1. Professional Assessment: Engage qualified remedial builders like Crownview Projects for a comprehensive assessment of your building’s concrete condition. Experienced professionals can identify spalling early on and recommend tailored solutions.

  2. Surface Repairs: Depending on the extent of damage, surface repairs such as patching, sealing, and protective coatings may suffice to address minor spalling issues. These measures effectively halt deterioration and restore the concrete’s integrity.

  3. Structural Rehabilitation: In cases of advanced spalling or structural compromise, more extensive rehabilitation measures may be necessary. This could involve concrete reparation, reinforcement, or even partial replacement to ensure the building’s stability.

  4. Preventive Maintenance: Implementing preventive measures such as regular inspections, moisture barriers, and corrosion protection systems can mitigate the risk of future spalling, prolonging the lifespan of the concrete structure.


Concrete spalling in strata buildings demands prompt attention and proactive intervention. By partnering with experts at Crownview Projects and prioritizing early treatment, strata owners and committees can safeguard their investments, enhance safety, and preserve the aesthetic appeal of their properties. Remember, addressing spalling today ensures a solid foundation for tomorrow.
