TS EN 13967

TS EN 13967 is a standard concerned with flexible sheets used in waterproofing, specifically plastic and rubber damp proof sheets and plastic and rubber basement tanking sheets. In practical building terms, these products form a continuous barrier intended to limit the passage of moisture, and in below-ground applications they are also associated with resistance to water ingress in more demanding conditions. The topic is the product family itself and its defining characteristics, rather than a single installation method.

Where these membranes fit in building protection

From a general technical perspective, damp proof sheets are used to interrupt capillary moisture migration and reduce the upward or lateral movement of moisture through building elements. Basement tanking sheets are a more demanding category, typically considered where substructure walls or floors may be exposed to groundwater-related conditions. The distinction matters because moisture control, liquid water resistance, and pressure resistance are not the same performance problem, even though the products may look similar in form.

Why terminology and material class matter

Flexible sheets are membranes designed to accommodate movement in the substrate and detailing at laps, corners, and penetrations. Plastic- and rubber-based products differ in polymer composition, flexibility, ageing behaviour, and field handling, so naming the material class helps users understand the intended application envelope. The phrase “definitions and characteristics” signals a technical vocabulary framework for identifying the product types and their basic attributes, without implying that every test, limit value, or installation requirement is stated here.

This withdrawn TSE edition still represents a useful reference point for understanding how waterproofing membranes are categorised in building technology. It is especially relevant when reading specifications, comparing membrane families, or distinguishing damp-proof layers from basement waterproofing systems that must perform under more severe exposure conditions.
