Targeted solutions for concrete cancer (spalling) to restore strength, safety, and longevity.
Stopping Concrete Cancer at the Source
Concrete cancer occurs when steel reinforcement within a slab or member rusts and expands, displacing surrounding concrete. This leads to cracking, delamination, leaks, and progressive degradation that can compromise structural integrity in buildings, bridges, tunnels, and other infrastructure. Early diagnosis and professional remediation are critical. Where structural concerns are suspected, we work alongside structural engineers to assess damage, determine causes (moisture ingress, carbonation, chloride attack), and deliver a durable repair strategy.
How to Spot It — and How We Fix It
Common indicators that your structure may be affected by concrete cancer include:
Signs & Symptoms:
Delaminated or cracking concrete (spalling)
Rust stains appearing to “bleed” from within concrete
Bubbling/plating of render
Leaks in overhead slabs or internal walls
Concrete cracking, crumbling, or expanding outward
Typical Remedial Approach:
Detailed inspection, testing, and mapping of affected areas
Removal of delaminated concrete to sound substrate
Cleaning and treatment/passivation of corroded reinforcement
Reinstatement with appropriate repair mortars/patching systems
Protective coatings and waterproofing to prevent reoccurrence
Ongoing monitoring/maintenance recommendations
