TS EN 13967/A1

TS EN 13967/A1 is the A1 amendment to TS EN 13967, which addresses flexible plastic and rubber sheets used for damp proofing in buildings. The subject includes sheets intended for basement tanking, so the document sits within the technical area of building moisture protection, where product definitions, characteristics, and conformity assessment are central. In other words, it establishes the common technical language used to describe this type of membrane and the performance attributes by which it is assessed.

The technical role of damp proofing sheets

Flexible plastic and rubber sheets are continuous barrier layers used to limit the passage of water and moisture through the building envelope. In general technical practice, they are applied in foundations, basements, and other moisture-sensitive parts of a structure to reduce the risk of damp ingress. “Basement tanking” refers to a waterproofing arrangement around or against the basement structure; in that application, continuity of the sheet, joint detailing, and material behavior are especially important.

What this document covers

• Flexible plastic and rubber sheets for damp proofing of buildings
• Products used for basement tanking
• Definitions and characteristics
• Requirements and test methods
• Evaluation of conformity of the product to the standard

The A1 designation identifies this record as an amendment to the base standard rather than a stand-alone product specification. It belongs to the EN 13967 framework, so it should be understood as part of the established technical vocabulary and performance structure for damp proofing membranes. For procurement and specification work, its value lies in aligning product description, testing, and declared characteristics within one recognized standard family.
