You have a foundation ready for waterproofing and an excavator waiting to backfill. Release the buried work only after you check the wall, selected water-control system, drainage, protection, and required inspections. Name who accepts each part before the next crew covers it.
Separate the packages in the trade scope. A completed wall does not tell you who installs the membrane, seals service penetrations, connects the footing drain, or protects the finished work. Use this guide as a coordination record alongside the approved design and selected product instructions.
Confirm the system before assigning the work
Ask the designer to identify the required wall treatment and drainage for this foundation. Distinguish damp-proofing from waterproofing in the scope. PNNL explains that damp-proof coatings are not completely waterproof and describes drainage as a separate part of foundation water management. Below-grade wall guidance
Record the foundation type, intended treatment, design revision, and selected products. Have the responsible designer and product representative resolve compatibility or site-condition questions. A membrane example from another job does not establish the correct system for this one.
For NC work, confirm the code edition and amendments applicable to the permit with the inspection department. OSFM publishes code references, amendments, and implementation notices. Use those references when the team disputes a requirement. NC code references
Before mobilizing, agree on the current detail for corners, the wall-to-footing joint, top termination, and every service penetration. Record who approves a substitution or field change. Keep that approval with the installation package.
Assign four scopes and their receiving checks
Use the table to settle responsibilities before the crews price or start the work. The assignments below are questions for this project, not standard contract inclusions.
Scroll to read all columns.
| Package | Assign a named company or contact | Receiving check to record |
|---|---|---|
| Concrete or masonry wall | Who repairs voids, removes protrusions, supplies wall records, and resolves structural questions? | Waterproofing installer accepts the substrate against the selected product instructions. |
| Waterproofing | Who supplies primer, membrane or coating, corner details, penetration seals, termination, and repairs? | Named reviewer checks the completed treatment before protection hides it. |
| Foundation drainage | Who installs the drain, filter material, drainage layer, connections, and approved discharge route? | GC and drainage installer confirm the route and record concealed connections before backfill. |
| Excavation and backfill | Who prepares access, installs protection if assigned, places approved fill, and coordinates final grades? | Excavator receives the documented release and agrees how it will protect the wall treatment and drain. |
Do not leave a task between bids. If the waterproofing installer excludes drain connections and the excavator excludes them too, assign that gap before either starts. Use the trade handoff checklist to record who leaves the work and who receives it.
Have the installer accept the substrate
Ask the installer to check the wall before application. Record unresolved surface repairs, curing information, moisture conditions, and access. Keep structural crack or loading questions with the responsible designer.
W. R. Meadows’ MEL-ROL instructions address curing, clean and dry surfaces, irregularities, primers, and application conditions. Those requirements belong to that product. Have the installer use the current instructions for the specified system. MEL-ROL substrate and application guidance
Attach the product instructions and accepted detail to the work order. Name who supplies the repair materials and who checks the repaired surface. If the installer rejects an area, identify it by wall and location, assign the repair, and record the recheck before proceeding there.
Check penetrations and the drainage route together
List sleeves, pipes, and other wall penetrations before application. Identify the installing trade and waterproofing detail for each one. Ask who repairs the water-control layer if a later trade makes another opening.
MEL-ROL has specific details for drains and protrusions, corners, and the footing connection. Use those details only for that system. Ask the specified manufacturer to resolve a missing or conflicting detail before concealment. Manufacturer detailing guidance
Trace the planned drain from the foundation to its discharge. PNNL describes footing drains, filter material, and connections to discharge arrangements such as daylight or a sump. Its guidance identifies municipal approval for a storm-sewer connection. Confirm this project’s permitted outlet with the designer and relevant authority. Footing drain guidance
Record who owns the pipe, outlet, sump, power connection, and any later access where those items apply. Check the connection before fill hides it. Avoid treating a roll of drainage mat as evidence that the complete drain route is finished.
Separate inspection approval from the installation check
Ask the inspection department which foundation or concealed-work inspections apply and when the work must remain visible. Raleigh calls for foundation and crawl-space inspection before backfill. Other jurisdictions may use a different checklist. Raleigh inspection timing
NC law authorizes inspections during construction to check applicable laws and permit terms. Retain the actual result and any required correction. A requested inspection is a scheduling record, not an approval. G.S. 160D-1113
Keep the manufacturer’s installation review and the permit inspection as separate records. One addresses the selected system and agreed scope; the other addresses the authority’s requirements. Ask each reviewer what evidence it needs before protection or soil covers the work.
Record evidence before concealment
Prepare a dated handoff record for the wall or area being released. Suggested fields include:
- Current design revision, approved product package, and accepted changes.
- Substrate check, repair locations, and the installer’s acceptance.
- Photos identifying corners, joints, penetrations, terminations, and drain connections.
- Installation checks or tests required by the selected system and project.
- Required inspection result, correction owner, and reinspection status.
- Protection and drainage-layer completion.
- Approved discharge route and remaining connection work.
- Named release contact, receiving excavator, exceptions, and recheck date.
Photographs support the record; they do not replace required inspection or testing. Take the evidence while the details are visible. Give the receiving crew access to the same drawings and accepted changes.
Release backfill after protection and open items are checked
Have the installer and excavator review protection before fill placement. MEL-ROL’s instructions require checking and repairing the membrane before covering, then providing protection or the specified drainage layer. They also address avoiding damage during backfill. Follow the selected system’s requirements. Inspection, protection, and backfill guidance
Confirm required inspection approvals, completed corrections, protected surfaces, and the drainage connection before releasing that area. Obtain the designer’s structural backfill conditions separately. Do not infer a wall’s loading readiness from the membrane’s application date.
If damage appears during backfill, stop covering the affected area. Name who repairs it and who accepts the repair. Reopen the handoff record rather than relying on the earlier release.
Keep final grading and roof-water discharge on later visits in the home-building sequence. PNNL connects wall treatment with grading, gutters, and foundation drainage. Carry those interfaces into the later scopes and closeout record. Foundation water-management guidance
