Waterproofing Auckland
Auckland's trusted waterproofing contractor for roofs, decks, basements, gutters and below-ground structures. Long-lasting membrane systems installed by licensed applicators.
Auckland's wet, humid climate is hard on buildings. Constant rain, salt air and freeze-free but damp winters mean water will always find the weakest point in your building envelope. When it does, the damage rarely stays small — rot, mould, ruined interiors and failed structures all start with one unsealed joint.
Membrane Roofing Applicators provides complete waterproofing services across Auckland, from flat roofs and decks to basements, retaining walls and gutters. With over 15 years of membrane experience, we install and repair proven waterproofing systems that are engineered to last, not just to pass the next rain.

Waterproof Membrane Systems We Install
The right membrane depends on the surface, the traffic it takes and the exposure. We work with liquid-applied membranes, torch-on systems and thermoplastic membranes — including GAF and SEALCO membrane systems — so we can specify the correct solution for your Auckland property rather than forcing a one-size-fits-all product.
Every system we install is backed by correct surface preparation, detailing at upstands and penetrations, and proper falls to drainage — because most waterproofing failures come from poor detailing, not the membrane itself.

Frequently Asked Questions
How much does waterproofing cost in Auckland?
Cost depends on the area, the surface condition and the membrane system specified. Small deck or gutter repairs are relatively low cost, while full roof or basement tanking is a larger investment. We provide a free on-site inspection and a fixed written quote so there are no surprises.
How long does waterproofing last?
A correctly installed membrane system can last 15–30+ years depending on the product and exposure. The biggest factor is installation quality and detailing, which is exactly where a specialist applicator makes the difference.
Do you handle both repairs and new waterproofing?
Yes. We repair failing and leaking membranes as well as install complete new waterproofing systems for roofs, decks, basements, retaining walls and gutters across Auckland.
