Paver spalling is localized flaking or loss of material from a paving-unit surface or edge, distinct from downward pavement settlement.
Describe material loss rather than a cause
CMHA maintenance guidance addresses assessment of pavement condition. Spalling describes loss from the unit itself. It differs from a white deposit, a stain or an entire unit moving downward, and appearance alone does not identify the mechanism. See CMHA operation and maintenance of interlocking concrete pavement.
Record exposure and treatment history
Note known cleaning products, coatings, impacts and when the change appeared. Do not assume salt, manufacturing defects or pressure washing caused it without evidence. Whole-area photographs and close views can support a product-specific assessment.
Cleaning cannot replace missing material
Removing dirt may clarify the surface but does not rebuild a chipped face. Sealer also does not restore lost unit thickness or certify durability. An unsuitable aggressive treatment can obscure the assessment rather than resolve the condition.
Repair versus replacement scope
Discuss whether individual affected units need replacement and whether neighboring material shows the same issue. Product matching and surrounding support matter. Where loss creates a sharp or uneven walking surface, report that observation and keep people away from the hazard.
Planning the next step
Identify whether the pavement carries pedestrians, vehicles or poolside traffic and provide photos of the full area, not just one joint. Mention previous repairs, known coatings and where runoff travels. Ask which observations support the proposed treatment and whether supporting layers need assessment. This guide concerns conventional concrete pavers unless a different system is specifically identified; natural stone, mortared and permeable assemblies require their own guidance.

Frequently asked questions
Is spalling the same as efflorescence?
No. Spalling is material loss; efflorescence is a mineral-deposit term.
Can sealer restore missing paver material?
No. A coating does not rebuild the unit.
Does one chipped paver prove all units are defective?
No. Extent, history and product assessment are needed.
