What Is Bathroom Waterproofing?
Bathroom waterproofing is the process of applying a waterproof membrane to floors, walls, and wet areas - like your shower - before tiling. It's what actually stops water getting through, not the tiles or grout: water passes through tile joints constantly, and it's the membrane underneath that keeps it out of your walls and floor structure.
In New Zealand, bathroom waterproofing isn't optional. It's required under NZ Building Code Clause E3 for every wet area, and for consented work it must be carried out by a qualified applicator and signed off with a PS3 Producer Statement. Done properly, it protects the timber framing, plasterboard, and concrete underneath your tiles from moisture, mould, and long-term structural damage.

Bathroom Waterproofing Requirements in NZ at a Glance

PS3 Certification & Auckland Council Compliance
Under NZ Building Code Clause E3, there are strict bathroom waterproofing requirements that apply to every wet area - and if your project requires council consent, those requirements must be independently verified.
We provide a PS3 Producer Statement upon completion, confirming the work complies with NZ Building Code (E3 Internal Moisture), follows approved systems and standards, and was completed by a qualified applicator.
PS3 Certified – Council Compliant – Done Right the First Time
Water damage in a bathroom doesn’t start big — it starts silently, behind your tiles.
A small failure in waterproofing allows moisture to seep into your walls and floors. Over time, that leads to mould, rot, structural damage, and costly repairs that often require ripping the entire bathroom apart.
** The truth:
Most bathroom failures in Auckland happen because waterproofing was either done incorrectly or not done to code.
At Dakom Tiling, we make sure that never happens.
We provide PS3-certified bathroom waterproofing in Auckland, fully compliant with NZ Building Code Clause E3 and accepted by the Auckland Council for consented work.
What Happens When Waterproofing Is Done Wrong
Most issues aren’t visible until it’s too late.
By the time you notice something, you could be dealing with:
- Tiles lifting or cracking
- Persistent damp or musty smells
- Black mould inside the walls
- Rotten timber framing
- Concrete substrate damage
And at that point, it’s no longer a simple fix — it’s a full bathroom rebuild.
We regularly fix failed waterproofing jobs across Auckland. In almost every case, the cause is the same: poor application, wrong products, or no certification.
How We Waterproof Bathrooms (Properly)
We don’t cut corners – because corners are exactly where most leaks start.
Using ARDEX-certified waterproofing systems, we apply membranes as a complete system (not mismatched products), ensuring long-term performance.
Every project includes:
- Full waterproofing of shower floors and walls
- Sealing of floor-to-wall junctions (critical failure point)
- Reinforcement of internal/external corners
- Proper sealing around pipes, drains, and penetrations
- Correct membrane thickness + curing time before tiling
The result: a fully sealed wet area system, built to last – not just pass inspection.
