A new handbook to reduce health issues caused by trapped moisture in concrete subfloors

Trapped moisture in concrete subfloors can lead to serious issues from mould growth, flooring adhesive degradation, and more. Standards Australia is drafting a handbook to provide guidance on moisture testing in concrete subflooring, a measure that can help mitigate these issues early on.

Addressing Industry Challenges

Moisture-related issues in flooring installations have long been a concern for the wider community as well as industry professionals. Problems such as mould growth, adhesive breakdown, and overall flooring failure are the most widely known concerns. These issues not only compromise the structural integrity of buildings but also pose health risks and lead to significant economic losses. Standards Australia’s new handbook SA HB 245, Moisture Testing for Floor Covering Installations on Internal Concrete Substrates, seeks to mitigate these problems by offering clear testing methods that can be universally applied across various flooring materials and conditions.

Benefits to Industry Professionals

  • Standardisation and Clarity: Currently, other building sectors such as waterproofing, ceramic, and restoration use the moisture testing method set out in the resilient and textiles standards AS 1884 or AS 2455. The development of this handbook aims to help all segments integrate their approaches and gain a better understanding of which test method will benefit their product for a successful outcome.
  • Enhanced Decision-Making: With detailed information and a clearer understanding of the various testing methods and their applicability, professionals will be able to choose the most appropriate test method suited for their specific needs. This reduces the potential risk of floorcovering failures, and the associated costs of repairs and potential litigation.
  • Improved Health and Safety: By addressing moisture issues effectively, the handbook aims to help prevent the growth of mould and the release of noxious odors from adhesive breakdown. This contributes to healthier indoor environments and could reduce overall workplace health and safety risks.
  • Cost savings: Standardised moisture testing may lead to reduced costs by preventing floor failures and reducing the need for costly repairs. It may minimise the risk of potential litigation related to moisture-related issues, providing economic stability for businesses.
  • Environmental Impact: Effective moisture management helps in reducing waste and preventing environmental contamination. By providing guidance on durable and reliable flooring installations, the handbook supports increasingly sustainable building practices.

Comprehensive and Inclusive Approach

The development of this handbook, led by Standards Australia committee, PL-015, Resilient Flooring, is a collaborative effort, engaging stakeholders from different sectors of the flooring industry. This inclusive approach ensures that the handbook addresses the needs and concerns of relevant parties, making it a truly comprehensive resource.

“One of the standout features of the proposed handbook is its focus on reliability to the building industry and equipping professionals with the tools to confidently perform the relevant tests and accurately interpret the results. Its aim is to align international standards with Australian conditions, addressing a wide range of factors such as dew point, site conditions, concrete additives, and more, ensuring accurate moisture testing,” says PL-015 committee Chair, Gary Eggers.

The handbook will provide an overview of each test method, including its benefits and limitations. It will also cater to a range of flooring materials, including resilient flooring, textiles, among others. This approach aims to support professionals in making informed decisions based on reliable data, tailored to the specific needs of their projects.

“For industry professionals, this handbook is not just a guide but a valuable tool that will support their work, helping them deliver high-quality, durable flooring solutions,” says Standards Australia’s Chief Operations Officer, Kareen Riley-Takos

SA HB 245 represents a significant step forward for the Australian flooring industry. By providing clear guidelines, it aims to enhance the quality and reliability of flooring installations, benefiting professionals and end-users alike. This initiative underscores Standards Australia’s commitment to excellence, health, safety, and sustainability, paving the way for a more resilient and robust flooring sector.

It is anticipated that the handbook will be completed by 2026.
