Clay Geosynthetic Barriers - Characteristics required for use in the construction of underground structures (other than tunnels and associated structures)
This document specifies the characteristics of clay geosynthetic barriers (GBR-C) as well as multicomponent geosynthetic clay barriers (e.g. a GBR-C with a polymeric or bituminous geosynthetic barrier attached to it), when used as fluid barriers and separation layer in the construction of underground structures (other than tunnels and associated structures), and the appropriate test methods to determine these characteristics.
If in a multicomponent GBR-C, the GBR-P or GBR-B is the predominant hydraulic barrier then the appropriate standard should be used.
The intended use of these products is to control the leakage of fluid through the construction wall.
This document 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 document defines characteristics to be considered with regard to the presentation of performance.
This document does not cover applications where the geosynthetic barrier is to 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.
Geosynthetische Tondichtungsbahnen - Eigenschaften, die für die Anwendung beim Bau von Tiefbauwerken (andere als Tunnel und damit verbundene Tiefbauwerke) erforderlich sind
Dieses Dokument legt die Eigenschaften von geosynthetischen Tondichtungsbahnen (GBR-C), sowie geosynthetischen Tondichtungsbahnen aus Verbundwerkstoffen (z. B. eine GBR-C mit einer angebundenen Kunststoff- oder Bitumendichtungsbahn), die als Abdichtung und Trennschicht beim Bau von Tiefbauwerken (mit Ausnahme von Tunneln und verbundenen Strukturen) eingesetzt werden, sowie die geeigneten Prüfverfahren zur Bestimmung dieser Eigenschaften fest.
Wenn bei einer GBR-C aus Verbundwerkstoffen, die GBR-P oder GBR-B die überwiegende, hydraulische Dichtungsbahn darstellt, dann sollte die entsprechende Norm für diese angewendet werden.
Die bestimmungsgemäße Anwendung dieser Produkte ist das Durchsickern von Flüssigkeiten durch die Bauwerkswand zu kontrollieren.
Dieses Dokument ist nicht anwendbar auf Geotextilien oder geotextilverwandte Produkte im Sinne der Definition von EN ISO 10318 1.
Dieses Dokument behandelt die Bewertung und Überprüfung der Leistungsbeständigkeit (AVCP) des Produkts nach dieser Europäischen Norm, einschließlich der Verfahren für die werkseigene Produktions-kontrolle.
Dieses Dokument legt Eigenschaften fest, die in Bezug auf die Darstellung der Produkteigenschaften berücksichtigt werden müssen.
Dieses Dokument umfasst nicht die Anwendungen, bei denen die geosynthetische Dichtungsbahn in Kontakt mit Trinkwasser kommt, das für den unmittelbaren menschlichen Gebrauch behandelt wurde.
ANMERKUNG Wo Trinkwasser in direkten Kontakt mit dem Produkt kommt oder kommen kann, können andere einschlägige Normen, Anforderungen und/oder Bestimmungen bei der Planung berücksichtigt werden.
Géosynthétiques bentonitiques - Caractéristiques requises pour l'utilisation comme barrière aux fluides dans la construction de structures souterraines (hors tunnels)
Le présent document spécifie les caractéristiques applicables aux géosynthétiques d'étanchéité incluant les géosynthétiques bentonitiques (GSB) et les géosynthétiques bentonitiques multicomposants (par exemple, GSB auquel est fixée une géomembrane polymérique ou bitumineuse), lorsque ces éléments sont utilisés comme barrières aux fluides dans la construction de structures souterraines (hors tunnels et structures associées), ainsi que les méthodes d'essai qui permettent de déterminer ces caractéristiques.
Si, dans un GSB multicomposants, la GMB-P ou la GMB-B est la barrière hydraulique à long terme prédominante, il convient d'appliquer la norme appropriée.
Ces produits sont destinés à contrôler les fuites de fluide à travers le mur de construction.
Le présent document ne s'applique pas aux géotextiles ou produits apparentés, tels que définis dans l'EN ISO 10318 1.
Le présent document permet d'évaluer et de vérifier la constance des performances du produit à la présente Norme européenne et les procédures de contrôle de la production en usine.
Le présent document définit les exigences que les fabricants et leurs représentants agréés doivent satisfaire concernant la présentation des propriétés du produit.
Le présent document ne couvre pas les cas où le géosynthétique bentonitique doit être en contact avec une eau traitée destinée à la consommation humaine.
Si de l'eau potable est ou peut être en contact direct avec le produit, il convient que le concepteur se réfère également aux normes, exigences et/ou règlements applicables.

The functions and conditions of use, corresponding with the S-coded characteristics in Table 1, are specified in 4.4. The performances of the characteristics are given on basis of the results of tests specified in this document and, where relevant, in accordance with 5.1. Information on how functioning joints can be made should be provided. Where products are jointed in the factory the liquid tightness and if relevant the strength of the joints shall be tested and data presented.

This should be restricted to a consideration of the substrate onto which the material is laid and/or chemicals contained. 18 Wetting/drying S CEN/TS 14417 In accordance with Annex A To determine the property of wetting/drying the test method EN 16416 is required. 19 Freezing/thawing S CEN/TS 14418 In accordance with Annex A To determine the property of freezing/thawing the test method EN 16416 is required. a NOTE The 95 % confidence level corresponds to the mean value minus (and/or plus) a tolerance value (see Annex ZA, Table ZA.1 column Notes). Both the mean value and the tolerance value are defined by the manufacturer to be representative of the performance of the product for the corresponding characteristic (these two values are not necessarily based on a statistical calculation). Relevance of codes:
A: relevant to all conditions of use
S: relevant to specific conditions of use
“—”: indicates that the characteristic is not relevant for that product Particular site-specific application cases may contain requirements for additional properties and - preferably standardized - test methods, if they are technically relevant and not conflicting with European Standards. The design life of the product should be determined, since its function may be temporary, as construction expediency, or permanent, for the lifetime of the structure. 4.4 Characteristics relevant to specific conditions of use 4.4.1 General The necessary data based on the test requirements and test methods described in this document for the functions and conditions of use described as relevant (see Table 1) in the project specification shall be provided. The list of characteristics in Table 1 includes those relevant to all conditions of use (A) (essential characteristics are listed in Table ZA.1), and those relevant to specific conditions of use (S). These specific conditions of use (S) are listed from 4.4.2 to 4.4.5. If the product under consideration is a multicomponent barrier, the performance of the claimed GBR shall dictate the characteristics listed in Table 1. SIST EN 16994:2018
