Geosynthetic barriers. Characteristics required for use as a fluid barrier in the construction of tunnels and associated underground structures
| Published By | Publication Date | Number of Pages |
| BSI | 2013 | 44 |
This European Standard specifies the relevant characteristics of geosynthetic barriers, including polymeric geosynthetic barriers, clay geosynthetic barriers and bituminous geosynthetic barriers, when used as fluid barriers in the construction of tunnels and associated underground structures, and the appropriate test methods to determine these characteristics.
The intended use of these products is to control the leakage of water through the construction wall.
This document is not applicable to geotextiles or geotextile-related products.
This document provides for the evaluation of conformity of the product to this document.
This document defines requirements to be met by manufacturers and distributors with regard to the presentation of product properties.
This document does not cover applications where the geosynthetic barrier is to be in contact with water that has been treated for human consumption.
Where potable water is or may be in direct contact with the product the designer should also refer to other relevant standards, requirements and/or regulations.
