Small Concrete Cavities Need a Pattern Description Before a Repair Choice
A few small cavities and a broad flaking surface can look similar in a cropped photograph. Before requesting a patch or a replacement quote, describe the shape, distribution and surrounding condition. That helps a reviewer consider the right question without diagnosing every small hole as the same form of deterioration.
Notice the distribution
From an accessible location, show the whole area and several representative close views. Note whether the cavities appear isolated, clustered or part of more widespread material loss. Do not dig out particles or create fresh openings to make the condition easier to identify. An overall pattern often provides context that a single dramatic close-up leaves out.
Use technical names carefully
NRMCA describes aggregate popouts as localized cavities related to a near-surface particle, while its scaling guidance addresses flaking of the finished surface. These are different descriptions, not remote diagnoses of your concrete. Ask what evidence supports the reviewer’s proposed classification and whether another condition must be considered. The apparent size of one cavity does not establish the extent of the overall problem or the condition beneath it.
Discuss the purpose of the response
Identify whether the concern affects appearance, cleaning, intended use or a wider repair plan. Ask what the proposed scope would address and what remains uncertain. A localized treatment and a larger surface intervention may serve different purposes; neither should be selected solely because one photograph resembles an online example. Preserve relevant history and any change over time so the recommendation can be based on the property’s actual evidence.

Worked example
Illustrative example: a fictional owner finds several small cavities after cleaning an outdoor slab. The inquiry includes an overall view and identifies the scattered pattern. The reviewer can ask a focused classification question instead of receiving a single close-up labeled complete surface failure.
