A remedial builder needs more than a leak location.
Before waterproofing remediation begins, the builder should understand what problem they are being asked to solve.
A statement such as “Water is leaking through the balcony” is not a remedial waterproofing scope.swer.
What should happen before tender?
The process should ideally be:
Defect → Investigation → Testing → Diagnosis → Scope → Tender → Remediation → Verification
This separates technical diagnosis from construction execution.
What should a remedial waterproofing scope include?
Depending on the project, the scope may address:
Existing conditions: What is currently present?
Defect locations: Where have defects been identified?
Extent: How far does the remediation need to extend?
Preparation: What existing finishes or materials need to be removed or prepared?
Substrate: What substrate requirements need to be met?
Detailing: Which junctions, penetrations and interfaces require attention?
Waterproofing system: What performance requirements apply to the proposed system?
Testing: What testing is required during or after the works?
Completion: How will the completed work be assessed?
Why clarity matters to remedial builders
An unclear scope can create uncertainty around:
• quantities
• preparation
• interfaces
• access
• materials
• testing
• variations
• responsibility
A well-defined technical scope gives the builder a clearer basis for pricing and construction.
Independent investigation does not replace the builder
The role of an independent waterproofing consultant is different from that of a remedial contractor.
The consultant investigates and provides technical advice.
The builder delivers the remediation.These roles can work together.
The goal is not simply to produce a report
A waterproofing investigation should ultimately help answer:
What needs to be done, where, and why?
That information can then be translated into a practical remedial scope.
The quality of a remedial waterproofing project often depends on what is understood before construction starts.
Diagnose the problem first. Define the scope second. Remediate with confidence.

How We’re Different From a Waterproofing Contractor
| Waterproofing Integrity | Waterproofing Contractor | |
|---|---|---|
| Diagnoses the cause | Independent testing before any recommendation | Often assumes, based on the job being priced |
| Recommends the fix | Specifies what’s correct, regardless of who installs it | Recommends what they install |
| Financial interest in the outcome | Advisory fee only | Paid to perform the work |
| Verifies the finished work | Independently tests and reports on the completed work | Self-verifies their own work |
