Following best practices for SN 564271:2021 compliance is crucial for ensuring effective waterproofing in construction projects and for preparing for audits. Adhering to these best practices helps organizations meet regulatory standards set forth by the Swiss Society of Engineers and Architects (SIA) and ensures quality and reliability in waterproofing methodologies.

Best practices at a glance

This checklist presents 7 best practices that cover critical aspects of waterproofing as outlined in SN 564271:2021. Each practice corresponds to specific clauses in the standard, emphasizing the importance of thorough execution, quality assurance, and compliance with building physics principles.

The practices

  1. Implement Comprehensive Quality Assurance Processes
    Establish a robust quality assurance framework to monitor waterproofing work continuously. This practice mitigates the risk of water ingress and structural damage, ensuring compliance with Section 6 of SN 564271:2021, which emphasizes quality control measures.

  2. Ensure Proper Air Tightness and Vapor Barriers
    Focus on achieving effective air tightness and installing vapor barriers in line with Section 4 of SN 564271:2021. This practice prevents moisture migration and condensation, which can lead to mold growth and damage, thereby meeting auditor expectations regarding building performance.

  3. Adopt Secondary Waterproofing Techniques
    Implement secondary waterproofing systems as a safeguard against primary system failure. This aligns with the guidelines in Section 5 of SN 564271:2021, which stress the importance of redundancy in waterproofing to mitigate risks from extreme weather events.

  4. Incorporate Thermal Insulation Solutions
    Integrate thermal insulation within the waterproofing design to enhance energy efficiency and prevent thermal bridging. Section 7 of SN 564271:2021 highlights the significance of thermal management in building physics, which is essential for compliance.

  5. Design Effective Water Drainage and Disposal Systems
    Ensure proper water drainage and disposal systems are in place to direct water away from structures. Compliance with Section 8 of SN 564271:2021 is crucial to prevent water accumulation, which can compromise waterproofing integrity.

  6. Utilize Proper Connections and Terminations
    Pay attention to connections and terminations within the waterproofing layer, as outlined in Section 9 of SN 564271:2021. Proper detailing prevents potential failure points, ensuring a continuous and effective waterproofing barrier.

  7. Verify Construction Physics
    Conduct thorough construction physics verification to ensure that all waterproofing measures are effective under expected conditions. Section 10 of SN 564271:2021 mandates this verification, which is essential for compliance and audit readiness as well as long-term performance of waterproofing systems.
