TS EN 13969

TS EN 13969 is the standard for flexible reinforced bitumen sheets used as damp proofing in buildings. It focuses on the technical definition and characteristic properties of these products, including sheets intended for basement tanking and other below-ground moisture-control applications. In practical terms, it helps define how this type of waterproofing material is identified, assessed, and compared within building envelope and substructure use.

What the standard covers

The document covers definitions and characteristics for flexible reinforced bitumen sheets intended for damp proofing of buildings. That distinction matters because these products are not just generic bituminous membranes: they are designed for moisture control in construction, where continuity, compatibility with the substrate, and resistance to water-related exposure are central technical concerns. Basement tanking sheets are included within the intended use, reflecting their role in protecting underground structures against damp ingress.

Requirements, test methods, and conformity

According to the scope, the standard specifies requirements and test methods and provides for evaluation of conformity with those requirements. From a general technical perspective, that means the product family is assessed through defined characteristics rather than by appearance alone. In the waterproofing field, reinforced bitumen sheets typically combine a bituminous waterproofing layer with a reinforcement carrier, so the balance between flexibility, mechanical stability, and moisture resistance is a key part of product performance.
