Waterproofing FAQs in Porirua

How much does waterproofing cost in NZ?

Waterproofing costs in NZ typically range from $50–$150 per m² depending on the system used. A standard bathroom wet area (3–5 m²) costs $500–$1,500; a deck membrane coating may cost $3,000–$8,000 depending on size.

Is waterproofing required by NZ building code?

Yes. NZ Building Code clause E3 requires all wet areas (showers, baths, laundry floors) to be waterproofed. Waterproofing must be carried out before tiling and inspected before being covered.

How long does waterproofing last?

Quality membrane waterproofing systems last 10–25 years. Durability depends on correct application, substrate preparation, and exposure conditions. Regular inspection is recommended every 5 years.

Can I tile over existing waterproofing?

Only if the existing waterproofing is intact and compatible with your adhesive. In most renovation scenarios, old waterproofing should be removed and reapplied to ensure full Code compliance.
