scope:

This European Standard specifies the characteristics of geosynthetic barriers including polymeric geosynthetic barriers, clay geosynthetic barriers and bituminous geosynthetic barriers, used as fluid barriers and separation layer in infrastructure works, e.g. roads, railroads, runways of airports, and the appropriate test methods to determine these characteristics.

Tunnels and associated underground structures are addressed in EN 13491.

The intended use of these products is to control the pathway of fluid through the construction and to limit any contamination, e.g. by de-icing products, of groundwater or water sources.

This European Standard is not applicable to geotextiles or geotextile-related products, as defined in EN ISO 10318-1.

This document provides for the assessment and verification of constancy of performance (AVCP) of the product to this European Standard including factory production control procedures.

This European Standard defines characteristics to be considered with regard to the presentation of performance.

This European Standard does not cover applications where the geosynthetic barrier will be in contact with water that has been treated for human consumption.

NOTE Where potable water is or can be in direct contact with the product, other relevant standards, requirements and/or regulations can be considered for the design.
