Waterproofing

The foreman's below-grade checklist: what to sign off at each stage before backfill

By Review.LivePublished 3 min readHow we write

The winery cellar’s form has one box marked waterproofing complete. The protection crew arrives at wall section four while a detail correction is still open. The foreman needs a checklist that shows the stage and boundary, rather than another overall signature.

Use one located checklist per practical wall section, with separate entries for the actual stages and their required release evidence. Keep completed, held and not-applicable conditions distinct. A useful checklist lets the next person see what can be covered, which reference governs the work and what still needs a decision. It supports the project’s inspection process without turning the foreman’s signature into an approval outside their authority.

Replace one completion box with useful stage records

  1. Define the section. Mark its gridlines, elevation limits and adjoining interfaces on the current drawing. Give the checklist and photographs the same identifier. Choose boundaries the crew and reviewer can find on site, rather than dividing the work only by calendar day.
  2. Build entries from the actual sequence. Use the approved assembly to identify substrate, primer where applicable, membrane, details, repairs, protection, drainage and other relevant stages. Do not require a fictitious primer step for a system that has none; show why an entry is not applicable.
  3. Write an observable check. State the approved reference and evidence expected for each entry. Include the location, date and responsible person. Replace a vague good-quality box with the relevant condition or required record, leaving technical limits to the governing document.
  4. Identify who checks and releases each stage. Separate the crew’s self-check from consultant, manufacturer or other required reviews. Mark the applicable hold points and notice requirements. A self-check can record preparation while the covering release remains conditional on another person’s review.
  5. Keep exceptions on the same sheet. Number defects, unanswered details and corrections by location. Name an owner and next action, then link closure and any recheck. Avoid filing the accepted entries in one folder and the still-open exceptions where the protection crew cannot see them.
  6. Hand over the actual boundary. Before the next layer begins, brief its lead on released and held areas. Retain the completed sheet, current references and located photographs together. Record later changes separately so a past signature cannot be mistaken for acceptance of altered work.

Common mistakes

  • Requiring stages absent from the specified assembly.
  • Treating self-checks as every required external review.
  • Separating open exceptions from the covering handover.

Checklist

A stage sheet worth keeping

  • Findable wall-section boundary.
  • Actual applicable stages and current references.
  • Observable checks and located evidence.
  • Named check and release responsibilities.
  • Open exceptions with closure and rechecks.
  • Accurate next-layer handover.

Check your understanding

Every applicable self-check is signed, but a required before-cover review remains outstanding. What should the sheet show?

Show the answer
Show the completed self-checks and the outstanding review separately. Keep the covering release conditional for its defined area. The checklist should explain the status rather than hiding the remaining requirement behind an overall completion box.
