Building envelope / Project guide
Below-grade water ingress investigation
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.
Start with the information below, then choose your property type for the access, operating and decision-making details that shape the project.
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.
Choose your property type.
Condominium buildings
Envelope work can involve balconies, windows and exterior walls alongside the interiors of affected homes.
Rental apartment buildings
Envelope work in an apartment building needs a link between exterior observations and resident reports.
Office buildings
Office envelope work may affect exterior access and business activity inside perimeter suites.
Retail properties
Retail envelope work can affect storefronts, signs and entrances used throughout trading hours.
Hotels
Hotel envelope work may affect guest-room windows, exterior access and the appearance of arrival areas.
Warehouses and distribution properties
Warehouse envelope work can involve walls, doors or openings next to loading and storage operations.
Mixed-use buildings
Envelope work on a mixed-use building can affect homes above commercial premises and shared entrances below.
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.
Working checklist

Project: Below-grade water ingress investigation
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.
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.
Continue planning.
Window replacement project
A replacement proposal that explains window selection, installation details, interior work and verification responsibilities.
Facade condition assessment
A location-based condition record with observed concerns, assessment limits and recommendations for further investigation or work.
Balcony repair planning
A coordinated repair proposal with identifiable balcony locations, investigation assumptions and resident-access responsibilities.
