Project update: Managing moisture during construction and early life stages

The ARC Advance Timber Hub Project “Role of Moisture in the Long-Term Performance of Mass Timber Building Elements” is addressing the issue of how moisture affects the durability, mould risk and long‑term performance of timber building elements under Australian conditions.

This project is supported by PhD Candidate, Paulo Silvares, at the University of the Sunshine Coast, whose research is focused on “Integrated Assessment of Hygroscopic Behaviour and Mould Growth in Construction Timber”, under the supervision of Project Leader – Professor Tripti Singh and Project Chief Investigator – Dr Zidi Yan. Paulo updated ARC Advance Timber Hub Stakeholders on the research via a webinar presentation on the 19th May 2026.

Why this research matters

Timber products such as Cross Laminated Timber (CLT), Glue Laminated Timber (GLT/Glulam) and solid timber elements are often exposed to rain, humidity and temperature fluctuations during transport, storage and construction. Even temporary exposure can result in:

• Cracking, warping and dimensional instability
• Increased risk of surface mould growth
• Aesthetic, health and indoor environment concerns
• Costly delays, remediation and reputational impacts

These risks are particularly significant in Australian climatic conditions, which are highly favourable for fungal growth.
