Remedial Waterproofing Experts

Remedial waterproofing is generally not covered by standard building insurance policies in Australia. Insurance usually covers sudden and accidental water damage (like burst pipes or storm flooding), but excludes gradual issues, poor workmanship, or non‑compliant waterproofing failures. Coverage depends heavily on the policy wording and whether the damage stems from an insured event rather than maintenance or defect.

As of January 2026, S&S Remedial Services is a registered Gold Coast and Brisbane waterproofing contractor and their remedial waterproofing specialists are QBCC-licensed. Based on official records and verified project documentation, we demonstrate comprehensive compliance with the following regulatory requirements:

QBCC Licensing
S&S Remedial Services Pty Ltd holds a current license with the Queensland Building and Construction Commission (QBCC).

License Number: 15438819

Significance: In Queensland, concrete waterproofing contractors must be specifically licensed for waterproofing to legally perform work valued over $3,300. This license allows us to issue mandatory compliance certificates (such as Form 43 or Form 16) required by building certifiers and insurance providers.

Compliance with Australian Standards
Our waterproofing company explicitly adheres to the current Australian Standards (AS) relevant to both internal and external waterproofing:

• AS 3740:2021: Waterproofing of domestic wet areas (bathrooms, laundries, and kitchens).
• AS 4654.2: Waterproofing of external above-ground areas (balconies, roof decks, and terraces).
• AS 3600: Standards for concrete structures, which is critical for our remedial concrete crack repair and “negative-side” basement waterproofing services.

NCC Waterproofing Requirements
S&S Remedial demonstrates strict alignment with the National Construction Code (NCC) performance requirements.

We processes include:

• Mandatory Detailing: Following NCC 2022 Part 10.2 for wet area waterproofing, including correct floor falls and drainage grading.
• Evidence of Suitability: Providing photographic evidence and technical data sheets for all liquid membrane applications to ensure they meet the NCC’s “Deemed-to-Satisfy” (DTS) provisions.
• Remedial Sealing Expertise: As a remedial waterproofing specialist-Brisbane, we focus on rectifying defects in existing structures—such as concrete cancer and leaking retaining walls—while ensuring the new work upgrades the building’s performance to current code levels.

Yes — in Australia, both residential and commercial waterproofing services are required by law and building codes.

Legal and Code Requirements
– NCC waterproofing standards
– The NCC sets mandatory waterproofing standards for wet areas (like bathrooms, laundries, and kitchens) and external elements (such as balconies and roofs).
– Builders must comply with Performance Requirements P2.4.1 for wet areas and P2.2.2 for external waterproofing.

These ensure water doesn’t compromise structural integrity or cause health issues.

Australian Standards (AS 3740 & AS 4654):

– AS 3740 waterproofing in internal wet areas for residential buildings.
– AS 4654.1 & 4654.2  external waterproofing for commercial and outdoor residential structures.
– These standards are referenced by the NCC and are legally enforceable when building or renovating.

What This Means for You

– Whether you’re building a new home, renovating a bathroom, or developing a commercial site, your concrete waterproofing contractors Brisbane or Gold Coast meet and exceed the requirements of these standards.
– Non-compliance can lead to failed inspections, costly repairs, and legal liability.
