TS EN 13967+A1

TS EN 13967+A1 is a standard for the definitions, characteristics, requirements and test methods for flexible plastic and rubber sheets used for damp proofing in buildings, including basement tanking. It provides the technical basis for describing these products and for assessing whether they meet the stated performance criteria.

The technical purpose of flexible damp proof sheets

In general technical terms, plastic and rubber sheets act as continuous barriers that limit the passage of moisture and water through the building envelope. For such products, properties such as thickness, tensile behaviour, watertightness, resistance to handling damage and the ability to maintain continuity at joints are particularly important. In basement tanking, these sheets are used in contact with below-ground structures, where protection against ground moisture and water influence makes material continuity and detailing especially critical.

Product group and conformity framework covered by the document

• Flexible plastic and rubber sheets intended for damp proofing in buildings
• Plastic and rubber basement tanking sheets
• Definitions and characteristics for these product types
• Requirements and test methods stated in the standard
• Technical basis for evaluating product conformity

As a result, the document is more than a material description: it establishes a shared technical language for a family of sheet products. For design, material selection, installation and quality assurance, consistent understanding of terms and characteristics helps support reliable comparison, detailing and application in the field.
