Waterproofing Systems
Leaking iron roofs, flat roofs holding water, failed flashings and split joints — we specify seamless, liquid-applied waterproofing systems that flex with the building and keep water out for decades, not seasons.
Noxyde
elastomeric roof membrane
Fillcoat Fibres
instant leak repair
Panel Bond
joints & flashings
Eagle DoubleCoat
ponding water
Water always finds the weakest detail
New Zealand's driving rain, thermal movement and long wet spells expose every weakness in a roof or deck. Sheet systems fail at joins; brittle coatings crack as the substrate moves. Liquid-applied membranes cure into one continuous, flexible skin that covers the whole surface including the awkward details.
We match the system to the problem: elastomeric Noxyde for iron and steel roofs that also need corrosion protection, Fillcoat Fibres for fast repairs on damp surfaces, Panel Bond Bandage to reinforce joints and flashings, and Eagle DoubleCoat where water simply never drains away.
Why our systems last
- Seamless, liquid-applied — no sheet joins to fail
- Stays flexible so it moves with the building instead of cracking
- Systems rated for ponding and continual water immersion
- Applied over prepared rust, concrete, membrane and steel
- 20+ years of proven New Zealand waterproofing performance
Where leaks start — and how we fix them
Leaking iron roofs
Rusted laps, failed fasteners and hairline splits let water through. A flexible, seamless membrane bridges movement and seals the whole roof rather than patching symptoms.
Flat roofs that never dry
Ponding water destroys ordinary coatings. Eagle DoubleCoat is built for continual immersion and standing water on flat concrete and membrane roofs.
Joints, flashings and penetrations
Most leaks start at a detail, not the middle of a sheet. Panel Bond Bandage permanently seals laps, flashings, gutters and penetrations before the coating goes on.
Emergency leaks in wet weather
Fillcoat Fibres can be applied to damp surfaces to stop a leak today, then be built into a longer-term system once conditions allow.
Waterproofing products we supply
Noxyde, Fillcoat Fibres, Panel Bond Bandage and Eagle DoubleCoat — used on their own or combined into a complete waterproofing system.
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.

Fillcoat®Fillcoat® Fibres Instant Waterproofing
Stop the leak today — no plumber required.
Fillcoat® Fibres repairs holes and cracks up to 2mm instantly, even in the wet. Faster and considerably cheaper than a call-out, and it stays flexible through the seasons.

MMPPanel Bond Waterproofing & Flashing Bandage
Seal joints, flashings and laps — permanently.
Used by our contractors as a joint sealant in cool stores, as a remedial fix for roof flashings, and across the waterproofing industry wherever a durable, flexible bandage seal is needed.

Built for water that never drains away.
A liquid elastomeric waterproofing membrane reinforced with microfibres and a high aluminium content, for waterproofing and continuous ponding water — i.e. internal gutters. Eagle DoubleCoat provides waterproofing and solar reflection on most types of roof surface including galvanised steel, iron, zinc, asbestos, cement, roofing felt, asphalt and bituminous roof coatings.

Rust-OleumNoxyde Plus®
Can be applied directly to prepared rust. Stop corrosion for decades.
When steel starts to rust, most coatings simply hide the problem — Noxyde® Plus is engineered to stop it. Built on the performance that has protected New Zealand structures for decades, it brings the latest European coating technology for greater corrosion resistance, stronger adhesion and improved long-term performance. Used in the same places as Noxyde: rusty iron roofs, structural steel, industrial plant and commercial buildings.
