Below-grade water ingress investigation for retail
Prepare an investigation of water entering below-grade walls, parking or service spaces. Connect indoor observations with the site, drainage and earlier repair history so a qualified provider can define a useful assessment.
The decision this helps you make
What to aim for.
A documented understanding of the observed entry paths, investigation limits and options for further assessment or corrective work.
Retail envelope work can affect storefronts, signs and entrances used throughout trading hours. Describe the observed problem and identify the store and property contacts who can coordinate exterior access and questions about the scope.
Define the scope.
- Identify affected walls, slabs or spaces and describe when water entry occurs.
- List nearby site features and known drainage or waterproofing work for review.
- Ask the provider to separate investigation, temporary measures and permanent corrective options.
Put these records together.
- Collect available below-grade drawings, drainage plans and earlier waterproofing or repair reports.
- Provide dated photographs and observations associated with rainfall or other site conditions.
- Identify access restrictions, adjoining property contacts and any occupied operations affected by investigation.
For retail
Fit the work around the property.
Retail property work needs a clear account of trading hours, customer movement and the assets shared by different occupants. Start with the shop, unit or common area involved and identify the problem or planned change. Describe whether the request concerns the wider property, an individual tenant’s space or both, with scope boundaries marked for the property team to confirm. Owners and managers need comparable proposals, while store contacts can explain deliveries, peak periods and activities that make certain work windows difficult. A useful brief includes entrances, loading routes, shared parking and the places where materials could be held during the job.
For food or other specialist tenants, identify the business contact who can explain operating needs directly to the provider. Ask how the proposed work will be communicated to affected stores and how unexpected findings will be reviewed. At completion, collect records for the shared asset and any tenant-specific work. A location-based handover helps the manager deal with callbacks and gives each store a clear account of changes affecting its premises.
Decisions and responsibilities
- Property owner or asset manager approving shared-asset work
- Centre or property manager coordinating tenants and common areas
- Store representatives explaining trading, deliveries and access needs
Service-specific scope

- Discuss staging and work sequences around deliveries and customer pedestrian routes.
Access and operations
- Customer entrances, service corridors and delivery windows
- Material staging coordinated with parking and pedestrian movement
- Store appointments arranged around trading and specialist operating needs
Questions for the provider
- Which parts of the storefront or exterior belong within the proposed project?
- How will the provider document completed repairs and any conditions needing separate review?
Ask for a comparable proposal.
- Define the assessment areas and the assumptions about access to concealed construction.
- Separate testing, opening-up, excavation or specialist input from the initial investigation.
- Ask the report to explain findings, unresolved questions and the basis of each proposed option.
Understand what affects the cost.
Ask providers to price the same scope and explain the assumptions behind these items.
- The depth and accessibility of the affected construction and surrounding site areas.
- The investigation needed to distinguish possible entry paths or connected drainage issues.
- Parking, tenant or neighboring-property coordination and restoration after investigative work.

Project: Below-grade water ingress investigation · Property: Retail properties
Agree on the handover.
- Keep a marked location record and photographs documenting the investigation findings.
- Record temporary measures and any monitoring requested by the responsible professional.
- Obtain a separate corrective-work brief with access, restoration and verification responsibilities.
- Shared-asset records plus any separate tenant completion notes
- Open items identified by unit, entrance or common-area location
Questions before you begin.
Should we request excavation as the first step?
Describe the observations and ask the provider to explain an appropriate investigation sequence. Have the proposal distinguish what can be assessed initially and what further access may be needed.
What makes a waterproofing repair proposal easier to compare?
Start with the same investigation findings and affected areas. Ask providers to explain repair boundaries, access, reinstatement, assumptions and verification so the options can be assessed against the same problem.
Who should coordinate below-grade water ingress investigation for retail?
Confirm the responsible contact among Property owner or asset manager approving shared-asset work; Centre or property manager coordinating tenants and common areas; Store representatives explaining trading, deliveries and access needs. Give the provider one person who can supply records, arrange access and take questions back to the decision-maker.
Continue planning.
