Geotextiles and geotextile-related products - Characteristics required for use in the construction of tunnels and underground structures
This European Standard 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.
The intended use of these geotextiles or geotextile-related products is to protect geosynthetic barriers used in tunnels and underground structures.
This European Standard is not applicable to geosynthetic barriers, as defined in EN ISO 10318 1.
This European Standard provides for the assessment and verification of constancy of performance of the product to this European Standard and for factory production control procedures.
Particular application cases may contain requirements regarding additional properties and – preferably standardized – test methods, if they are technically relevant.
This European Standard may be used to derive design values by taking into account factors within the context of the definitions given in EN 1997 1 (Eurocode 7), e.g. factors of safety. The design life of the product should be determined, since its function may be temporary, as a construction expediency, or permanent, for the lifetime of the structure.

Overview
EN 13256:2016 is the CEN European Standard that defines the characteristics and test methods for geotextiles and geotextile-related products used to protect geosynthetic barriers in the construction of tunnels and underground structures. It prescribes how manufacturers should declare product performance, and it specifies procedures for assessment and verification of constancy of performance (AVCP) and factory production control (FPC). This standard is focused on protection products and is explicitly not applicable to geosynthetic barriers themselves (see EN ISO 10318-1).
Key topics and requirements
- Intended function: Protection of geosynthetic barriers in tunnel and underground works; additional functions (drainage, erosion control) are addressed by other standards where integrated.
- Declared characteristics: Manufacturers must provide relevant performance data for characteristics identified in the standard (e.g., tensile and seam strength, puncture resistance, friction, resistance to mechanical damage, resistance to weathering, oxidation and hydrolysis).
- Test methods: Reference to standardized tests (for example, wide‑width tensile test EN ISO 10319, static puncture CBR EN ISO 12236, dynamic perforation EN ISO 13433, weathering EN 12224, hydrolysis EN 12447, friction EN ISO 12957 series) to determine declared values.
- Durability and service life: Guidance on assessing product service life (temporary or permanent use) and repeat testing after durability exposures; Annexes provide detailed durability approaches for different service-life scenarios.
- AVCP and FPC: Procedures for product type determination (PTD), factory production control, initial inspection, continuous surveillance and verification of declared values. Annex A gives an FPC scheme and test frequencies.
- Regulatory linkage: Supports requirements under the EU Construction Products Regulation and provides guidance on Declaration of Performance (DoP) and CE marking (see informative Annex ZA).
- Design integration: Can be used to derive design values in the context of Eurocode 7 (EN 1997-1), taking into account factors of safety.

The EN 13256:2016 standard provides essential guidelines for geotextiles and geotextile-related products specifically utilized in the construction of tunnels and underground structures. Its scope is meticulously defined to encompass the characteristics required for these materials, along with the corresponding test methods necessary for their evaluation. This focus ensures that the geotextiles meet performance requirements critical for safeguarding geosynthetic barriers used in such environments. One of the key strengths of this standard is its clear demarcation of applicability, explicitly stating that it does not cover geosynthetic barriers as referenced in EN ISO 10318 1. By doing so, it delineates the specific role and requirements of geotextiles within the broader category of geosynthetic materials, preventing confusion and ensuring that stakeholders have a clear understanding of compliance needs. Moreover, EN 13256:2016 emphasizes the assessment and verification of the constancy of performance for products adhering to this standard, along with the establishment of factory production control procedures. This aspect is crucial for manufacturers, as it provides a framework for maintaining quality and consistency in the production of geotextiles, reinforcing reliability and safety in their application in tunnels and underground structures. The standard also recognizes the possibility of additional requirements based on particular application cases, which allows for flexibility and adaptation to specific project needs. This is significant, as it encourages the incorporation of technically relevant properties and standardized test methods that can be vital to the performance of geotextiles in diverse conditions. Furthermore, EN 13256:2016 facilitates the derivation of design values, integrating factors outlined in EN 1997 1 (Eurocode 7). This inclusivity is pivotal for engineering applications, as it allows for comprehensive risk assessment and the planning of safety factors directly related to the design life of the geotextiles, whether for temporary construction expediency or permanent structural integrity. In summary, the EN 13256:2016 standard stands out for its comprehensive approach to the characteristics of geotextiles used in tunnel and underground structure construction. Its detailed guidelines for testing, performance verification, and flexibility for additional requirements make it a vital reference for practitioners in the field, ensuring that safety, quality, and usability are prioritized in the use of these materials.
La norme EN 13256:2016, intitulée "Geotextiles and geotextile-related products - Characteristics required for use in the construction of tunnels and underground structures", se concentre sur les caractéristiques essentielles des géotextiles et des produits apparentés utilisés dans la construction de tunnels et d'ouvrages souterrains. L'une des forces majeures de cette norme est qu'elle définit les méthodes d'essai appropriées pour évaluer ces caractéristiques, assurant ainsi que les matériaux répondent aux exigences spécifiques nécessaires pour protéger les barrières géosynthétiques. Le champ d'application de cette norme est particulièrement pertinent, car elle précise que les géotextiles visés ne s'appliquent pas aux barrières géosynthétiques comme défini dans l'EN ISO 10318-1. Cela garantit une spécialisation et une clarté qui sont indispensables dans le domaine de la construction souterraine, où les conditions d'utilisation peuvent varier considérablement. En incluant des dispositions concernant l'évaluation et la vérification de la constance des performances, la norme renforce la confiance des utilisateurs en la durabilité et l'efficacité des produits. Une autre force de la norme réside dans sa capacité à s'adapter aux exigences particulières des cas d'application, ce qui est essentiel pour les projets variés rencontrés dans le secteur. Cela permet non seulement d'intégrer des propriétés supplémentaires, mais également d'exiger des méthodes d'essai, lorsqu'elles sont techniquement pertinentes, renforçant ainsi le niveau de standardisation tout en permettant une certaine flexibilité. De plus, la capacité à dériver des valeurs de conception à partir de cette norme, tout en tenant compte de facteurs relatifs à la sécurité mentionnés dans l'EN 1997-1 (Eurocode 7), ajoute une couche de sophistication dans la planification et la mise en œuvre des projets de construction souterraine. Le fait que la durée de vie du produit puisse être temporaire ou permanente, selon la fonction requise, souligne également l'importance d'une approche réfléchie à la conception et à l'application des géotextiles. Dans l'ensemble, la norme EN 13256:2016 se révèle être un instrument vital pour les professionnels de la construction souterraine, car elle fournit un cadre robuste pour l'utilisation et le contrôle des performances des géotextiles, tout en tenant compte des exigences techniques spécifiques du secteur.
