SIST EN 13967:2005/oprA2:2008

Overview

SIST EN 13967:2005/oprA2:2008 is a European standard developed by CEN that defines and specifies the characteristics of flexible sheets for waterproofing, specifically focusing on plastic and rubber damp proof sheets, including those used for basement tanking. The amendment prA2 updates definitions and requirements to facilitate consistency and reliability in waterproofing solutions across Europe. This standard is essential for manufacturers, designers, contractors, and regulatory bodies involved in the specification, installation, and quality assurance of waterproof membranes in construction.

Key Topics

• Scope and Definitions: Clarifies terminology around damp proof sheets, basement tanking, and waterproofing layers made from plastic and rubber, including polyolefin-based materials.
• Product Characteristics: Outlines essential properties that flexible waterproofing sheets must meet, such as:
  • Resistance to impact
  • Durability against chemical exposure
  • Compatibility with bitumen
  • Joint strength
  • Water vapor transmission properties
  • Reaction to fire
• Testing and Evaluation: Details standardized approaches for testing these characteristics, including references to related EN test methods and criteria for regulatory compliance.
• Regulatory Requirements: Specifies when certain characteristics must be evaluated, supporting both mandated regulatory oversight and voluntary quality assurance.

Applications

Flexible waterproofing sheets addressed by SIST EN 13967:2005/oprA2:2008 are vital in modern construction for maintaining the integrity and longevity of buildings. Typical applications include:

• Basement Tanking: Ensures the watertightness of below-ground structures by preventing water ingress through walls and floors, which is critical for both residential and commercial foundations.
• Damp Proof Courses (DPC): Installed in ground-level and below-ground masonry to block capillary rise of moisture, protecting building fabric and indoor environments from damp-related damage.
• Vapour Control Layers: Used in combination with insulation and structural layers to manage moisture within walls and floors, preserving structural performance and indoor comfort.
• General Waterproofing: Shields concrete slabs, walls, and other construction elements against ground moisture, making these sheets suitable for civil engineering, industrial, and infrastructure projects.

These applications help prevent structural deterioration, improve indoor air quality, and comply with building regulations concerning moisture and damp protection.
