From Defect to Scope: What Remedial Builders Need Before They Start

Waterproofing damage the membrane

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.
