“Diagnose quickly. Fix it once.”
42% of Australian buildings have waterproofing defects. The average repair cost is $283,000. When things go wrong, WI provides the independent expertise to diagnose the root cause, design the fix, and oversee the remediation, without any conflict of interest.
We work with engineers, remedial builders, waterproofing contractors, strata managers, developers correcting defects, and asset owners to provide:
- Diagnostic investigations — Combining applied water testing, thermal photography, moisture readings, and construction knowledge to identify or eliminate water ingress points. We work systematically to pinpoint the source, not just the symptom.
- Remedial design — Once the cause is identified, we design the rectification scope: specifying materials, detailing the approach, and defining the contractor scope of works.
- Contractor scope and management — We prepare clear scopes for contractors to quote against, and can manage the remediation process to ensure the fix is done right.
- Compliance testing of remedial works — After remediation, we test the new installation to verify effectiveness.
- Declared Designs (NSW) — For regulatory compliance, we provide documented waterproofing design declarations to support certification.
- Expert reporting — For strata disputes, builder defect claims, or insurance matters, our independent reports carry weight because we have no commercial interest in the outcome.
