A new national standard for concrete canvas will take effect in Kazakhstan on November 1, 2026. It sets unified quality requirements for material used to reinforce canals, slopes and water-management structures.
The standard, ST RK 4051-2026, “Concrete Canvas. Technical Specifications,” was approved by the chair of the Committee for Technical Regulation and Metrology of Kazakhstan’s Ministry of Trade and Integration.
The Kazakhstan Institute of Standardization and Metrology developed the document at the request of Kazakh Industrial Stroi LLP. It is intended to support domestic manufacturers and establish common requirements for producing, testing and using concrete canvas.
Concrete canvas is a geosynthetic composite made with a dry cement mixture. It gains strength and rigidity when wetted. The material is used to build, repair and restore hydraulic and other water-management structures.
Applications include reinforcing surfaces, slopes and embankments, and building drainage canals, irrigation and land-reclamation structures, artificial reservoirs and concrete channels. The standard does not cover materials for public highways or temporary roads.
The standard specifies properties including flexural and tensile strength, compressive strength of the cement mortar, resistance to static puncture, water impermeability, frost resistance and water absorption.
It also sets out product acceptance procedures and acceptance and periodic testing. Each batch must include a quality document listing the manufacturer, batch details, number of rolls and relevant test results.
