Problem:
Solid wood timber flooring is proposed for installation in wet areas (bathroom and ensuite) at a residential project in Victoria. Timber flooring is not a typical Deemed-to-Satisfy solution for wet areas under the NCC due to moisture risks such as swelling, warping, and deterioration.
Solution:
A Performance Solution was developed to allow the use of solid wood timber flooring in wet areas by selecting moisture-resistant timber species and applying advanced protective coatings, Rubio Monocoat Pure and Enviropro. These coatings ensure the flooring is waterproof, durable, and resistant to microbial growth, while maintaining its natural aesthetic. The system was assessed against NCC 2016 Volume Two Clause 3.8.1.2, with compliance achieved through expert judgment, product testing, and adherence to installation best practices, ensuring a sustainable, low-maintenance solution.
Finalised Report:
The final report confirms that the treated solid wood timber flooring meets the performance requirements for wet areas. Expert evaluation, combined with product testing and sustainable material selection, verified that the solution provides effective waterproofing, structural durability, and aesthetic retention. The approach offers a compliant, durable, and environmentally responsible flooring option, ensuring long term performance and low maintenance for the wet areas.
