SPARK BUILDING WAITAKERIES
Waterproofing a flat concrete roof in a high-rainfall zone.
The right system for a flat roof that takes heavy rain
Spark Building Waitakeries features a flat concrete roof exposed to large amounts of rainfall. Without the right coating, that combination leads to leaks, membrane breakdown and costly damage inside the building.
This is exactly why professional commercial roofing applicators turn to MMP Coatings — for proven, durable waterproofing systems they can trust in New Zealand conditions.
For this project, the contractor selected Doublecoat Aluminium waterproof membrane coating.
Waterproofing a flat concrete roof demands a professional product plus an approved applicator. Doublecoat Aluminium is applied like a conventional paint coating, yet it is built to take continual immersion. Its plasticised bitumen materials encapsulate the surface, sealing it completely and outlasting competing products. With over 20 years of reliable performance in New Zealand, it gives building owners confidence that the roof will stay dry, year after year.
Why standard roof coatings were not enough
- Flat concrete roof with heavy, year-round rainfall
- Standing water accelerates leaks and membrane breakdown
- Standard coatings cannot survive continuous immersion
Doublecoat Aluminium waterproof membrane coating
- Professional membrane coating formulated for ponding water
- Plasticised bitumen encapsulates and seals the surface
- Over 20 years of reliable performance in New Zealand

The right waterproofing system for every roof
This project demonstrates the importance of specifying the right waterproofing system. Not every roof coating is suitable for ponding water, which is why we work closely with contractors and property owners to recommend the correct solution for every application.

NoxydeNoxyde Anti-Corrosion Coating
Paint straight over prepared rust, stopping corrosion for decades.
Noxyde is the only anti-corrosion waterproofing membrane on the market that can be applied directly over clean, prepared rust — no separate primer required. For over 29 years it has protected New Zealand's most severe coastal environments, from saltwater estuary bridges to iconic steel roofs. It is also used to extend the life and safely encapsulate asbestos roofs, locking fibres in place and adding decades of waterproof protection without the cost of removal.
