BS EN 13984:2013

Comprehensive Waterproofing Standard for Building Construction

BS EN 13984:2013 is the essential standard for flexible sheets used in building waterproofing applications. This British Standard provides a robust framework of requirements, test methods, and terminology to ensure the quality and performance of these critical construction materials.

Detailed Specifications for Waterproofing Sheets

Developed by the British Standards Institution (BSI), this standard covers a wide range of specifications for flexible sheets, including:

• Material Composition: Polymeric sheets, bitumen-based sheets, and other flexible waterproofing materials.
• Physical Properties: Thickness, mass per unit area, tensile strength, resistance to tearing, and dimensional stability.
• Durability: Resistance to weathering, heat, and chemical exposure.
• Functionality: Water vapour transmission rate, water tightness, and compatibility with other construction materials.

Ensuring Compliance and Quality

By adhering to the requirements set forth in BS EN 13984:2013, construction professionals can be confident that the flexible waterproofing sheets they specify and use will:

• Provide reliable, long-lasting protection against water ingress.
• Maintain their physical and mechanical properties over the lifetime of the building.
• Comply with relevant building regulations and industry best practices.
• Integrate seamlessly with other construction materials and systems.

Key Benefits of Using BS EN 13984:2013

Improved Building Performance and Durability

Flexible waterproofing sheets that meet the stringent requirements of this standard will help to ensure the long-term integrity and performance of building envelopes. By preventing water penetration, these materials can protect against structural damage, mold growth, and other issues that can compromise the health and safety of occupants.

Compliance with Regulations and Standards

Compliance with BS EN 13984:2013 is often a mandatory requirement for construction projects, as it demonstrates that the waterproofing materials used meet the necessary performance and quality thresholds. This can help to streamline the approval process and ensure that buildings meet all relevant building codes and regulations.

Reduced Maintenance and Lifecycle Costs

The durability and reliability of flexible waterproofing sheets that conform to BS EN 13984:2013 can help to minimize the need for costly repairs and maintenance over the lifetime of a building. This can translate to significant cost savings for building owners and managers, as well as a reduced environmental impact from fewer material replacements.

By specifying and using flexible waterproofing sheets that meet the requirements of BS EN 13984:2013, construction professionals can ensure that their projects meet the highest standards of quality, performance, and compliance.
