Concrete Defects - Scaling

Scaling is one of the most common and costly forms of concrete surface deterioration. What often begins as minor flaking or surface peeling can progress into aggregate exposure, accelerated freeze-thaw damage, increased maintenance costs, and significant reductions in service life if left unaddressed.

The Scaling Field Reference was developed to help inspectors, contractors, technicians, engineers, and concrete professionals identify scaling, understand why it occurs, assess severity, and determine the appropriate repair and prevention strategies.

Using real-world examples, practical field guidance, severity classifications, inspection checklists, escalation triggers, and repair recommendations, this reference transforms a common durability problem into a clear and actionable field assessment.

Inside This Reference:

• Learn how to identify scaling and distinguish it from spalling, dusting, delamination, pop-outs, and other surface-related defects.

• Understand the most common causes of scaling, including freeze-thaw exposure, improper finishing practices, inadequate curing, excessive water, deicing chemicals, and insufficient air entrainment.

• Recognize warning signs ranging from minor surface flaking to deep aggregate exposure and progressive surface deterioration.

• Understand how scaling impacts durability, appearance, serviceability, and long-term performance.

• Assess severity using simple Minor / Moderate / Severe classifications.

• Apply the Universal Escalation Rule to identify conditions requiring additional investigation.

• Use a quick field decision process to determine when monitoring, repair, resurfacing, replacement, or further evaluation is appropriate.

• Review practical repair options based on the depth and extent of deterioration.

• Learn prevention strategies that improve long-term concrete durability and reduce future scaling risks.

• Utilize the included field inspection checklist for evaluations, documentation, and reporting.

• Reference applicable ASTM, ACI, and industry guidance related to durability, freeze-thaw resistance, air entrainment, and surface performance.
