Geotextiles and geotextile-related products - Characteristics required for use in earthworks, foundations and retaining structures
This European Standard specifies the relevant characteristics of geotextiles and geotextile-related products used in the construction of earthworks, foundations and retaining structures, and the appropriate test methods to determine these characteristics.
The intended use of these geotextiles or geotextile-related products is to fulfil one or more of the following functions: filtration, separation, and reinforcement. The separation function will always occur in conjunction with filtration or reinforcement, and hence will not be specified alone.
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 13251:2016 (CEN) defines the characteristics required for geotextiles and geotextile-related products used in earthworks, foundations and retaining structures. The standard specifies which product properties are relevant for intended functions - filtration, separation and reinforcement - and references the appropriate test methods to determine those properties. It also sets out procedures for assessment and verification of constancy of performance (AVCP) and factory production control (FPC) so manufacturers can declare performance consistently and comply with EU Construction Products Regulation requirements (see Annex ZA).
Key topics and requirements
- Intended functions: filtration, separation (always with filtration or reinforcement), and reinforcement.
- Scope exclusions: not applicable to geosynthetic barriers (see EN ISO 10318-1).
- Declared characteristics: includes stiffness (at 2%, 5%, 10%), tensile strength of seams/joints, static puncture (CBR), dynamic perforation, friction characteristics, tensile creep/creep rupture, resistance to damage during installation, and water permeability normal to plane.
- Durability and service life: Annex B addresses weathering, hydrolysis, oxidation and guidance for service lives (temporary or permanent) and required durability testing.
- Testing framework: normative references to international test standards (EN/ISO series) for sampling, tensile tests, puncture tests, permeability, friction tests, mechanical damage, and durability screening.
- Quality & conformity: procedures for Product Type Determination (PTD), FPC, initial inspection, continuous surveillance, Declaration of Performance (DoP) and CE marking (Annex ZA).
Practical applications
EN 13251:2016 is used when specifying, manufacturing, testing or approving geotextiles for:
- earthworks (embankments, road subgrades)
- foundation systems and ground improvement
- retaining structures and slope stabilization
- filtration/separation layers in drainage and soil‑reinforced systems
The standard helps derive design values in conjunction with geotechnical design codes (e.g. EN 1997‑1 / Eurocode 7) by clarifying characteristic properties and expected service life.
Who uses this standard
- Manufacturers for product specification, FPC and DoP preparation
- Designers and geotechnical engineers to select appropriate materials and derive design values
- Contractors and specifiers to ensure correct product performance on site
- Testing laboratories and certification bodies for AVCP and conformity assessment
- Regulators and procurement teams managing CE marking and construction product compliance
