What We Do

Waterproofing membrane inspection with measuring tape on concrete substrate

Waterproofing Design & Specification

Design reviews, material selection, and specification development for wet areas, balconies, roofs, basements, and podiums. Compliance to AS 4654.1, AS 4654.2, AS 3740, and NCC 2022. We get involved before construction starts, not after problems appear.

Waterproofing design drawings and compliance documentation on desk

Membrane Inspection & Testing

Hold point inspections at every critical stage — substrate preparation, primer application, membrane installation, drainage, flashings, and penetrations. Thickness testing against specifications. Transition detailing at junctions — the areas most likely to fail.

Leak Investigation & Remediation

Systematic leak source identification through non-destructive and invasive investigation methods. Forensic assessment of failed waterproofing systems. Remediation design and specification for residential and commercial buildings.

Compliance & Documentation

Photo registers, defect schedules, design declarations, and inspection reports formatted and referenced for engineering reports, tender packages, and NCAT proceedings. Evidence-based documentation — not opinion.

How We Work

2

Inspect

On-site inspection at each hold point. Substrate, membrane, drainage, finishes, flashings, and penetrations checked against spec. Thickness testing and junction transition assessment at every stage.
