Waterproof Membrane Decking for Durable, Low-Maintenance Outdoor Spaces
Seamless, long-lasting waterproofing for decks, balconies, terraces, and walkways.
Built to look good and stay watertight
MPM Waterproofing installs high-performance membrane decking systems that combine clean finishes with long-term waterproof protection across Auckland and Northland. Whether it’s a rooftop balcony, external walkway, or over-living area, we make sure your deck stays dry underneath and attractive on top.
We work with builders, developers, and homeowners to deliver code-compliant, trafficable membrane systems that hold up to New Zealand’s UV, rain, and temperature extremes, without cracking, bubbling, or lifting.
Our licensed applicators are trained across multiple systems, including trafficable sheet membranes and liquid-applied options. Every install is backed by full QA and product warranties.
Applications
Balconies over living spaces
Creates a waterproof barrier that protects internal rooms below from moisture damage.
Terraces and podium levels
Supports landscaping or paving finishes while maintaining waterproof integrity underneath.
Rooftop decks
Ideal for apartment or mixed-use buildings where aesthetics and watertightness are equally critical.
External stairs and landings
Prevents water ingress into building envelopes or framing beneath stairs and landings.
Walkways and pedestrian accessways
Provides a safe, low-slip surface with durable waterproof protection in high-traffic areas.
Renovation or recladding projects
Used to re-waterproof aged or failed membrane decks during reclads or deck rebuilds.
Our Process
-
We assess the deck substrate, drainage falls, flashing details, and finish requirements at your Auckland site to determine the most suitable membrane system before work begins.
-
We recommend a compatible trafficable or sheet membrane system suited to the deck use, exposure, and finish type. A detailed quote and scope of work will be provided before any work begins.
-
The deck surface is ground, cleaned, and primed, with all joints, transitions, and penetrations treated and prepared in accordance with system requirements.
-
Our certified applicators install the membrane including any required reinforcing layers or traffic coats, using system-specific methods and approved installation techniques.
-
A final inspection is completed under MPM's QA framework. We provide site photos and warranty documentation on completion.
