The SN 564271:2021 is a comprehensive standard published by the Swiss Society of Engineers and Architects (SIA). It outlines the essential requirements and methodologies for ensuring effective waterproofing in construction projects, specifically addressing waterproofing systems in buildings. This standard serves as a guideline for professionals in the construction sector, promoting best practices in waterproofing and ensuring compliance with industry expectations.

Purpose and objectives

The primary objective of the SN 564271:2021 is to establish clear and actionable guidelines for implementing waterproofing systems within various construction contexts. This standard aims to enhance the durability and performance of buildings by specifying criteria for waterproofing applications, which ultimately protects structures from water ingress and damage. The guidelines encompass various aspects of waterproofing, including the installation of vapor barriers, thermal insulation, and drainage systems, ensuring a holistic approach to building physics and construction integrity.

Scope: who must comply

SN 564271:2021 applies primarily to professionals in the construction industry, including architects, engineers, and contractors involved in building design and construction. It is particularly relevant to those working in sectors where waterproofing is critical, such as residential, commercial, and industrial construction. Companies that manufacture or install waterproofing materials and systems must also adhere to these standards to ensure compliance and quality assurance in their projects. Understanding the requirements outlined in SN 564271:2021 is essential for maintaining structural integrity and meeting regulatory standards in the construction materials and buildings context.

How SN 564271:2021 relates to other standards

SN 564271:2021 is part of a broader framework of standards related to construction and waterproofing. It is closely associated with:

• SIA 271: Focuses on the performance requirements for waterproofing and related building physics.
• SIA 272: Addresses the quality assurance processes in construction, ensuring that waterproofing solutions meet specified criteria.
• SIA 271/1: Provides additional guidelines and specifications for implementing waterproofing systems effectively.

These standards work in tandem to provide a comprehensive approach to waterproofing in construction, ensuring that all aspects of building performance are considered.

Revision history and current status

The SN 564271 was first published in 2021 and represents the latest revision in the series, incorporating updates based on advancements in building technologies and practices. The most recent revision in 2021 introduced more explicit compliance requirements and enhanced methodologies for waterproofing, reflecting current industry practices and findings. This ensures that the standard remains relevant and effective in addressing the challenges faced in modern construction projects.
