Waterproofing Services in Auckland

Waterproofing is one of those things most people don’t think about until something goes wrong – and by then, the damage is already done. A slow leak behind your shower tiles, moisture creeping under your balcony membrane, or water finding its way into a concrete slab can quietly destroy walls, floors, and structural elements over months or years. What starts as a damp smell or a few loose tiles often ends up as a costly remediation job.

Our company takes waterproofing seriously. Our team is PS3 certified and registered with Auckland Council, which means we meet the legal and technical requirements for waterproofing work in the Auckland region. We’re also fully insured and members of TANZ (Tiling Association of New Zealand) and Site Safe NZ. When we waterproof a surface, we do it to last – using only proven, manufacturer-approved systems from trusted suppliers like Mapei, Sika, Ardex, Bostik, and Technokolla.

Water is patient. It will find any gap, any imperfection, and any poorly applied membrane – and once it gets in, it doesn’t leave on its own. The consequences of poor waterproofing include:

• Structural damage – Prolonged moisture in concrete, timber framing, or substrate materials weakens the structure over time. What appears to be a surface problem is often a deeper one by the time it’s visible.
• Mould and health risks – Damp conditions behind tiles and under floors are ideal breeding grounds for mould and bacteria. This affects air quality and can cause ongoing health issues, particularly for children and people with respiratory conditions.
• Tile failure – Tiles rely on a stable, dry substrate. When water gets underneath, adhesive bonds break down, grout deteriorates, and tiles begin to crack or lift. Re-tiling without fixing the waterproofing underneath simply means repeating the problem.
• Cost of repair – A proper waterproofing job done once costs a fraction of what remediation work costs later. Stripping back a bathroom, treating mould, replacing substrate, and re-tiling from scratch is disruptive and expensive.

Getting the waterproofing right the first time is always the better investment.

We offer a full range of waterproofing solutions for residential and commercial properties across Auckland. Each service uses appropriate systems and products for the specific environment and surface type.

We only work with trusted suppliers and materials so our customers can be sure they will have the best results from start to finish.

PS3 is a Producer Statement issued by a certified specialist confirming that design or construction work has been carried out in accordance with the building consent and relevant standards. For waterproofing in Auckland, a PS3 from a registered author gives Auckland Council the assurance required for consent sign-off on applicable projects.

Dakom Tiling is a registered PS3 author – one of relatively few tiling and waterproofing companies in Auckland with this designation. If your project requires consent, or if you want the added certainty of a compliant, documented waterproofing system, we can provide that. It’s not something every waterproofing company can offer.

Our team works across both residential and commercial projects in Auckland and the wider region. Residential work ranges from single bathroom waterproofing for homeowners to full wet area systems for new builds and renovations. On the commercial side, we have experience with multi-unit apartment developments, retail and hospitality fit-outs, and larger concrete and deck waterproofing projects.

Whether your project is a single shower renovation or a large-scale commercial build, the standard of work is the same.
