Commercial Projects
Specialist waterproofing for body corporates, apartment complexes, commercial buildings, and large-scale projects across Auckland. NZ Building Code compliant. Licensed Building Practitioner.
Commercial waterproofing demands a different level of expertise compared to residential work. Larger roof areas, complex drainage systems, multi-level podium decks, and the need to coordinate with building occupants all require a contractor who understands the unique challenges of commercial construction.
At Your Subbie, we bring this expertise to every commercial project across Auckland. As a Licensed Building Practitioner (LBP #BP181755) with Roofing R4 & R5 endorsements, we are qualified to undertake restricted building work on commercial properties — a legal requirement that many waterproofing contractors cannot meet.
Our commercial division works with body corporates, property managers, construction companies, and building owners to deliver waterproofing solutions that comply with the New Zealand Building Code and stand the test of Auckland's demanding climate. We use only BRANZ-appraised waterproofing systems backed by manufacturer warranties.
Purpose-built waterproofing solutions for every commercial application
Large-scale flat roof waterproofing using TPO single-ply, torch-on bituminous, or liquid membrane systems. Engineered for commercial load requirements and long-term durability.
Multi-level podium deck and terrace waterproofing for apartment complexes and mixed-use developments. Critical detailing around penetrations, drainage, and expansion joints.
Below-grade tanking membrane systems for underground car parks, basements, and retaining walls. Prevents hydrostatic pressure damage and groundwater ingress.
End-to-end waterproofing services for body corporates including assessments, scope documentation, staged remediation plans, and warranty management.
Assessment and repair of existing commercial waterproofing systems. We identify failure points and implement targeted repairs or full system replacements.
Waterproofing installation for new commercial construction projects. We work with main contractors to deliver compliant installations within project timelines.
Every commercial waterproofing installation we complete is designed and installed to meet the requirements of the New Zealand Building Code. This is not optional — it's the law, and it's the foundation of every project we undertake.
All external waterproofing membranes comply with E2 requirements for weather-tightness
Systems meet minimum 15-year durability requirements for primary building elements
