Build a Concrete Repair History Without Turning Guesses Into Facts
An owner often inherits a repaired surface without inheriting the paperwork. You can still build a useful history if each entry says how it is known. Distinguish an invoice, an observation and something a previous occupant remembered. That small distinction helps the next reviewer understand what the record can support.
Label the source of each entry
Use plain labels such as “document supplied,” “person reported” and “date unknown.” Keep the original document beside the summary. If an invoice names a product, do not assume it establishes every application detail or that the same product was used across the whole property.
Record the gaps that affect a decision
Identify which missing facts matter to the proposed work. An unknown installation date may be less consequential than an unknown coating or a recurring water condition. Ask the reviewer to explain which gap needs more investigation before another layer or repair is approved.

Use one row for each field. Mark unknown information clearly and retain the original records.

Worked example
Illustrative example: a tenant remembers a garage patch “about three years ago,” while an invoice covers only the entry. Record two separate entries. Combining them into “all concrete repaired in 2023” would make the file look complete by making it less accurate.
