Wet Area Plasterboard & Compliance Tips for Adelaide Projects

If you're building or renovating in South Australia, especially in metro Adelaide, it's important to follow local building code requirements when working with wet areas. Bathrooms, laundries, and kitchens must be constructed with materials that can withstand moisture and humidity — and wet area plasterboard plays a key role in meeting compliance.

What Counts as a Wet Area?

Under the National Construction Code (NCC), wet areas include bathrooms, toilets, laundries, and parts of kitchens that are regularly exposed to water or steam. Local Adelaide councils apply these definitions and inspect accordingly during the building approval process.

Compliance Checklist for SA Builders

• ✔️ Use moisture-resistant plasterboard in all wet areas
• ✔️ Waterproofing membranes must be applied to shower enclosures and bath perimeters
• ✔️ All joints and penetrations must be sealed and compliant with AS/NZS 2588
• ✔️ Ventilation (natural or mechanical) is required in enclosed bathrooms and laundries

Recommended Product: Moisture-Resistant Plasterboard

We stock high-quality wet area plasterboard designed to meet NCC standards and Adelaide council expectations. These boards feature a water-repellent core and mould-resistant face paper — ideal for tiled surfaces or high-humidity zones.

Inspections & Council Approvals

Council inspectors may request proof of compliant wet area materials, especially in custom homes, developments, or bathroom renovations. Ensure you have product spec sheets and installation guides on hand (we’re happy to provide them with your order).

Common Mistakes to Avoid

• ❌ Using standard plasterboard behind showers or bathtubs
• ❌ Skipping ventilation fans in enclosed laundries
• ❌ Failing to seal junctions between wet area board and waterproofing membrane
