BS EN 13256 specifies the relevant characteristics of geotextiles and geotextile-related products used in the construction of tunnels and underground structures, and the appropriate test methods to determine these characteristics.
BS EN 13256 helps you improve the quality of tunnels and underground structures constructed using geotextiles and geotextile related products.
BS EN 13256 on geotextiles and geotextile related products — characteristics required for use in the construction of tunnels and underground structures is useful for:
The main function of geotextiles and geotextile-related products used in the construction of tunnels and underground structures is protection. If a drainage or erosion control system is integrated into the construction, the requirements of the appropriate standards shall also be fulfilled. BS EN 13256 allows manufacturers to describe geotextiles and geotextile-related products based on declared values for characteristics relevant to the intended use and if tested to the specified method. BS EN 13256 also includes procedures for the assessment and verification of constancy of performance and factory production control.
BS EN 13256 may also be used by designers, end-users and other interested parties to define which functions and conditions of use are relevant.
BS EN 13256 is part of a series of standards, addressing the requirements for geotextiles and geotextile-related products when used in a specific application. Annex C provides guidance on how to select the appropriate standard.
