GOST R 70090-2022 PDF

Full title and description

GOST R 70090-2022 — Geosynthetic bentonite roll waterproofing materials. General specifications (Russian title: Материалы геосинтетические бентонитовые рулонные для гидроизоляции. Общие технические условия). The standard establishes classification, technical requirements, safety measures, acceptance rules, test methods, and handling/transportation requirements for geosynthetic bentonite roll (bentonite mats / geosynthetic clay liners) used for waterproofing and anti-filtration barriers in civil, industrial and environmental engineering works.

Abstract

GOST R 70090-2022 specifies the terminology, product types, required physical and performance characteristics, and the methods to verify those characteristics for bentonite-based geosynthetic roll materials intended for waterproofing. It covers production and quality controls, criteria for acceptance, and instructions for packaging, transportation and storage. The document harmonises certain test methods with international references (ASTM/ISO) while setting national classification and application limits for use in tunnels, foundations, containment liners, road/rail embankments, hydraulic structures and waste containment.

Scope

The standard applies to geosynthetic bentonite roll waterproofing materials (commonly called geosynthetic clay liners or bentonite mats) intended for use in waterproofing of tunnels, foundations and underground parts of buildings and structures; construction of anti-filtration screens for disposal sites (municipal, industrial, radioactive waste) and their reclamation; anti-filtration screens for road and railway embankments; containment for oil & gas facilities and agricultural industry objects; and anti-filtration curtains in hydraulic engineering. It defines classification, manufacturing requirements, safety, acceptance rules, test methods, transportation and storage.

Key topics and requirements

• Definitions and classification of geosynthetic bentonite roll products (types of facing, bentonite mass per unit area, sodium vs calcium bentonite classes).
• Physical and performance requirements: surface mass, bentonite mass per unit area, moisture content, swelling index, fluid-loss (water‑loss) characteristics, tensile strength and elongation, filtration coefficient and flow intensity limits when used as anti-filtration barriers.
• Specified test methods and sampling procedures, with references to international and national test standards (e.g., ASTM D5891, ISO/EN test methods and relevant GOST/GOST R procedures).
• Rules for factory production control, acceptance inspection (including batch sampling and statistical acceptance), marking and documentation requirements.
• Requirements for packaging, transportation and storage to preserve bentonite properties and product integrity during handling and on‑site installation.
• Safety and environmental considerations for handling bentonite materials and geosynthetic components during manufacturing and installation.

Typical use and users

Primary users include geotechnical and civil engineers, waterproofing product manufacturers, quality and testing laboratories, construction contractors (tunnelling, foundation and landfill works), designers of containment and hydraulic structures, regulators and certifying bodies. Manufacturers and industry groups in the bentonite/geosynthetics sector used the standard to harmonise product specifications and testing after its introduction in 2022.

Related standards

The standard cross-references and aligns with multiple national and international documents and test methods, including (examples): ГОСТ EN 1928 (waterproofing membranes), ISO/EN and ASTM test methods for bentonite/geomembrane components, ГОСТ Р 50277 and other GOST/GOST R standards on geosynthetics and testing methods. Subsequent national standards (for example, newer Russian standards on bentonite profile seals and related products) reference and build on GOST R 70090-2022 for specific product classes.

Q: What does it cover?

A: It covers classification, required physical and performance characteristics, test methods, rules for acceptance, packaging, transportation and storage, and safety requirements for bentonite-based geosynthetic roll waterproofing products used in civil, industrial and environmental engineering.

Q: Who typically uses it?

A: Manufacturers of bentonite geosynthetic products, geotechnical and civil engineers, construction contractors (tunnels, foundations, landfills, embankments), testing laboratories, designers of containment systems and regulators.

Q: Is it current or superseded?

A: As published, GOST R 70090-2022 was approved in May 2022 and came into force on June 1, 2022. It is listed as an active national standard (first edition) and remains the current normative document for geosynthetic bentonite roll materials unless officially amended or replaced by a later Rosstandart order. For the latest status or amendments beyond 2022, consult the national standards registry or Rosstandart publications.

Q: Is it part of a series?

A: It belongs to the body of GOST R standards related to waterproofing and geosynthetics; specific product or application standards (for example, profile bentonite seals or sectoral technical conditions) may reference it or provide more detailed requirements for particular product types. Subsequent standards in the GOST R series have cited GOST R 70090-2022 as a reference for bentonite characteristic testing.
