This guide discusses the effects of timber exposure to excessive moisture, provides strategies to minimise moisture ingress during construction, and recommends remedial actions if necessary.
Introduction
It is essential to protect buildings from prolonged excessive exposure to moisture during construction. Timber and wood products are hygroscopic materials, meaning they can absorb (take in) or adsorb (let out) water from their surroundings. Wood, irrespective of age, always balances its moisture content with its surroundings.
Construction on building sites inevitably needs some level of remediation that may require budgetary and program allowance by the contractor. The guide focuses on mass timber buildings, generally associated with non-residential construction.
