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 with moisture meter on concrete wall

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.

When the Paperwork Is the Problem

No certificate, and someone is asking for one?

Selling or buying — wet-area work flagged The building report said “no certification sighted” and settlement is waiting. An independent evidence report answers the question without pulling up the tiles.

Council or a certifier is asking A Building Information Certificate application, an occupation certificate, unauthorised works — and the installer who could certify is long gone.

Renovating now, not yet tiled The cheap version of all of the above: record the waterproofing before it disappears under tiles, so this page is never about you.
